AB - Natural fibres have poor compatibility with polymers, which poses a problem when using them as reinforcement in green composites. We have successfully overcome this problem by attaching nano-size bacterial cellulose to the fibre surface using a strain of cellulose-producing bacteria, Gluconacetobacter xylinus. Natural fibre surfaces can be well covered by network of bacterial cellulose with our technique, which has changed the nature of the fibre surface and leads to an improvement in the interfacial shear strength (IFSS) between the fibres and the polymer. The potential of this novel technique in green composite fabrication was further investigated by incorporating the modified fibres into cellulose acetate butyrate (CAB) and poly-L-lactic acid (PLLA) matrices. Composites were manufactured and tested for tensile properties. The tensile strengths of the composites were found to increase significantly. Scanning electron microscopy (SEM) also confirmed the improved interaction between the fibre and the polymer matrix.
