Li M, Zhou S, Guan Q, Li W, Li C, Bouville F, Bai H, Saiz Eet al., 2022, Robust underwater oil-repellent biomimetic ceramic surfaces: combining the stability and reproducibility of functional structures, ACS Applied Materials and Interfaces, Vol: 14, Pages: 46077-46085, ISSN: 1944-8244

Robust underwater oil-repellent materials combining high mechanical strength and durability with superwettability and low oil adhesion are needed to build oil-repellent devices able to work in water, to manipulate droplet behavior, etc. However, combining all of these properties within a single, durable material remains a challenge. Herein, we fabricate a robust underwater oil-resistant material (Al2O3) with all of the above properties by gel casting. The micro/nanoceramic particles distributed on the surface endow the material with excellent underwater superoleophobicity (∼160°) and low oil adhesion (<4 μN). In addition, the substrate exhibits typical ceramic characteristics such as good antiacid/alkali properties, high salt resistance, and high load tolerance. These excellent properties make the material not only applicable to various liquid environments but also resistant to the impact of particles and other physical damage. More importantly, the substrate could still exhibit underwater superoleophobicity after being worn under specific conditions, as wear will create new surfaces with similar particle size distribution. This approach is easily scalable for mass production, which could open a pathway for the fabrication of practical underwater long-lasting functional interfacial materials.

Biological materials such as nacre have evolved microstructural design principles that result in outstanding mechanical properties. While nacre's design concepts have led to bio-inspired materials with enhanced fracture toughness, the microstructural features underlying the remarkable damping properties of this biological material have not yet been fully explored in synthetic composites. Here, we study the damping behavior of nacre-like composites containing mineral bridges and platelet asperities as nanoscale structural features within its brick-and-mortar architecture. Dynamic mechanical analysis was performed to experimentally elucidate the role of these features on the damping response of the nacre-like composites. By enhancing stress transfer between platelets and at the brick/mortar interface, mineral bridges and nano-asperities were found to improve the damping performance of the composite to levels that surpass many biological and man-made materials. Surprisingly, the improved properties are achieved without reaching the perfect organization of the biological counterparts. Our nacre-like composites display a loss modulus 2.4-fold higher than natural nacre and 1.4-fold more than highly dissipative natural fiber composites. These findings shed light on the role of nanoscale structural features on the dynamic mechanical properties of nacre and offer design concepts for the manufacturing of bio-inspired composites for high-performance damping applications.

Collett H, Bouville F, Giuliani F, Schofield Eet al., 2021, Structural monitoring of a large archaeological wooden structure in real time, post PEG treatment, Forests, Vol: 12, Pages: 1-13, ISSN: 1999-4907

Large archaeological wooden structures are potentially at risk of structural failure through deformation and cracking over time if they are left untreated and their structural health is not maintained. This could be in part due to, for example, the shrinkage of waterlogged wood as it dries, or time-dependent creep processes. These dimensional changes are accompanied by associated stresses. However, there are few studies analysing the movement of large wooden structures in real time as they dry, particularly after their conservation treatment. This paper follows the structural monitoring of the Mary Rose from after the conservation treatment, where it was sprayed with polyethylene glycol, through to the ship’s air-drying process and beyond to assess the effects that drying has had on the displacement of the timbers. A laser-based target system was used to collect displacement data between 2013 and 2020 and the data showed a significant slowing of displacement as the drying reached an equilibrium.

Materials that are transparent in the visible spectrum are useful in applications that range broadly from displays in portable devices to large-area panels and windows used in the construction industry. The high strength and hardness of silica-based glasses make them most suitable choice in many of these applications. However, such properties come at the cost of the low fracture resistance and low damage tolerance of glasses, which result in brittle and unpredictable failure with potentially dangerous and harmful outcomes. Strong and fracture resistant transparent materials are therefore in high demand in several structural applications. Inspired by the hierarchical structure of biological composites, researchers have been able to fabricate synthetic materials that combine high strength and toughness. Nevertheless, reconciling these mechanical properties with optical transparency does not constitute a trivial task. In this review article, we describe and discuss some of the most promising biologically templated and biologically inspired composite materials that have been proposed to combine optical transparency, strength and fracture toughness. The replication of some of the hierarchical features of biological materials within their structure allows these composites to take advantage of synergistic toughening mechanisms that act at different length scales and provide high resistance against fracture. Understanding how they are fabricated and which mechanisms contribute to their toughness is key to draw guidelines for the synthesis of future transparent, strong and tough composites that are safer and more reliable than state-of-the-art silica-based glasses.

Le Ferrand H, Bouville F, Studart AR, 2019, Design of textured multi-layered structures via magnetically assisted slip casting., Soft Matter

Multi-layered composites in nature often show functional properties that are determined by the specific orientation of inorganic building blocks within each layer. The shell of bivalve molluscs and the exoskeleton of crustaceans constitute prominent examples. An effective approach to artificially produce textured microstructures inspired by such complex composites is magnetically assisted slip casting (MASC). MASC is a colloidal process in which anisotropic particles are magnetically oriented at arbitrarily defined angles and collected at the surface of a porous mould to grow the material in an additive manner. Whereas a number of proof-of-concept studies have established the potential of the technique, the full design space available for MASC-fabricated structures, and the limits of the approach, have so far not been explored systematically. To fill this gap, we have studied both theoretically and experimentally the various torques that act on the particles at the different stages of the assembly process. We define the boundary conditions of the MASC process for magnetically responsive alumina platelets suspended in a low-viscosity aqueous suspension, considering the composition of the colloidal suspension and the dynamics of the particle alignment process under a rotating magnetic field. These findings lead to design guidelines for the fabrication of bio-inspired composites with customized multi-scale structures for a broad range of applications.

Grossman M, Bouville F, Masania K, Studart ARet al., 2019, Quantifying the role of mineral bridges on the fracture resistance of nacre-like composites

© CCM 2020 - 18th European Conference on Composite Materials. All rights reserved. The nacreous layer of mollusk shells holds design concepts that can effectively enhance the fracture resistance of lightweight brittle materials. Mineral bridges are known to increase the fracture resistance of nacre-inspired materials, but their role has been difficult to quantify. The challenge has been to isolate and control mineral bridge connectivity in a model composite with microstructures on the same scale as the biological material. In this study, we fabricate these tunable nacre-like composites from highly aligned alumina platelets, interconnected by titania mineral bridges and infiltrated with epoxy matrix phase, and experimentally quantify the influence of mineral bridge density on the fracture properties. Mineral bridge density from image analysis of composite cross sections was correlated with the fracture behavior in mechanical tests and a quantitative model was developed using the insight that shear lag describes the stress transfer through the mineral phase. This model quantitatively describes the relationship between the fracture strength of the composite, platelet strength, and mineral bridge density, which provides powerful guidelines for the design of lightweight brittle materials with enhanced fracture resistance. We illustrate this potential by fabricating nacre-like bulk composites with unparalleled fracture strength, 20% stronger than the previously reported materials.

Pelissari PIBGB, Bouville F, Pandolfelli VC, Carnelli D, Giuliani F, Luz AP, Saiz E, Studart ARet al., 2018, Nacre-like ceramic refractories for high temperature applications, Journal of the European Ceramic Society, Vol: 38, Pages: 2186-2193, ISSN: 0955-2219

High-temperature ceramics, so-called refractories, are widely used for the manufacturing of metals, for energy generation and aerospace applications. Refractories are usually strong and stiff but fragile due to the lack of plastic deformation and other intrinsic toughening mechanisms. This inherent brittleness limits their use in applications where catastrophic failure is not tolerated. The present work reports the design and fabrication of refractories with a bio inspired nacre-like microstructure comprising aligned alumina platelets, separated by an aluminium borate interphase, obtained through transient liquid phase sintering. The bioinspired composites exhibit high strength, 672 MPa, toughness, 7.4 MPa m1/2, and stable crack propagation at high temperatures, above 600 °C, due to the aluminium borate interlayer. This makes nacre-like ceramic refractories sintered with a transient liquid phase good candidate for high temperature applications, competing favourably with ceramic matrix composites and following a simpler and cheaper processing route.
