The Effects of Poly Dimethyl Siloxane on Water Absorption and Natural Degradation of Poly(lactic acid)/Oil Palm Empty Fruit Bunch Fiber Biocomposites

Composites were fabricated with poly(lactic acid) and oil-palm empty-fruit-bunch (EFB) fibers with extrusion; this was followed by an injection-molding technique. Before compounding, the surface of the fiber was modified through ultrasound and poly(dimethyl siloxane) (PDMS). The influences of the ul...
