Characterization of Laccase-Treated Kenaf Fibre Reinforced Recycled Polypropylene Composites

Raw and laccase-treated kenaf fibre (KF) were used individually to reinforce recycled polypropylene (RPP) using extrusion and injection moulding. Laccase was used to modify the surface of the fibre to improve the compatibility between fibre and matrix. Enzyme concentration and soaking time were cons...
