Microfluidics

The Polymers and Microfluidics group is centred on experimental soft condensed matter. We study complex fluids, often multicomponent systems, containing polymers, copolymers, (nano)-particles and surfactants.

Microfluidics provides unique opportunities to synthesise, formulate, process and analyse fluids and is therefore explored in our work.

Additionally, we employ extensively scattering (light, X-rays and neutrons), microscopy, calorimetry and spectroscopy - but we also develop our own measurement tools. Particularly, we resort to novel combinatorial and high-throughput techniques to address problems with large parameter space where conventional experimentation becomes unfeasible.

Current Research Projects

  • Thermodynamics and dynamics or polymer blends with a combination of real- and reciprocal-space techniques, including microscopy and AFM, and light and neutron scattering.
  • Local polymer dynamics in homopolymers, blends and nanocomposites, studied by calorimetry, spectroscopy and incoherent inelastic neutron scattering.
  • Microfluidics: both the fabrication of novel devices and applications in soft condensed matter and biology.
  • ‘Frontal photopolymerisation’ (FPP) theory and applications in rapid 3D microfluidic fabrication, particularly of solvent-resistant structures and microreactors.
  • Microfluidics applications include microchemical reactors, a fast "interfacial tensiometer", in-situ polymer/surfactant processing and inspection using scattering and microscopy, microfluidic manipulation and interrogation of motor neurons.
  • Fullerene association in model homopolymer matrices: bulk and thin film confinement, studied using microscopy, small angle scattering and reflectivity techniques.
