Preparation and characterization of modified polypropylene/ palm kernel shell (PP/PKS) biocomposites

The research on palm kernel shell (PKS) and polypropylene (PP) biocomposites consists of four parts. The first part is mainly to investigate the effect of incorporating PKS as filler on the mechanical, water absorption, morphology and thermal properties of PP. PKS (5-25 weight % filler loading) was...

The first part is mainly to investigate the effect of incorporating PKS as filler on the mechanical, water absorption, morphology and thermal properties of PP.
