| Research Abstract |
Wood-plastic composites (WPCs) are one of the effective uses of unutilized woody biomass such as forest residues. However, characteristics of WPCs such as lower impact strength and lack of weatherability restricts expansion of WPCs for the long term exterior use. To improve these characteristics, it is important to improve the compatibility between hydrophobic plastic and hydrophilic wood flour. In this study, we prepared natural compatibilizers which have hydrophobic chains or hydrophilic chains by solvolysis reaction of wood, and investigated compatibilizers' effects on impact strength and weatherability of WPCs. Results of Charpy impact test and accelerated weathering test revealed that the solvolysis products of wood with hydrophobic chains clearly improve the impact strength and weatherability of WPCs.
