Mechanical, water uptake properties, and biodegradability of polystyrene‐coated sisal fiber‐reinforced high‐density polyethylene

In this study, composites of high‐density polyethylene (HDPE) with uncoated sisal fibers (UF) and that coated (CF) with polystyrene (PS) and vinyltrimethoxysilane (VTMS) copolymers (PSV) were fabricated. The prepared copolymers containing 2.5% VTMS (PSa) and 5% VTMS (PSb) were used to coat the sisal fiber with a thin layer of hydrophobic polymer to make coated fibers CFa and CFb, respectively. The coating process was verified by...
