Abstract

The reinforcement efficacy of nano-silica particles for wood/plastic composites (WPCs) has been inconsistent in previous research. Accordingly, this systematic study was conducted to verify the reinforcement feasibility using silica particles. Micro- and nano-silica particles were incorporated into high-density polyethylene (HDPE) via direct compounding (dry dispersion) or by mixing in a solution (wet dispersion), to determine the effects of dispersion and particle size on the reinforcement efficacy of the resulting wood/HDPE composites. Compared with non-filled WPCs, dry dispersion reduced the WPCs’ mechanical strength for microsilica (> 30%), but increased it for nano-silica (
