Microwave-assisted Graft Copolymerization of Methyl Methacrylate onto Wood Fibers and its Application in Wood Plastic Composites

The present research aims to investigate methods to improve the material properties of wood plastic composites (WPC). WPCs, like any other natural fiber reinforced polymer composite, have poor interfacial bonding between the hydrophilic natural fibers and hydrophobic polymer matrix. In this study, the graft copolymerization technique is successfully used as treatment on wood fibers prior to fabricating the polymer composite. The WPCs produced with grafted wood showed marginally improved tensile strength and reduced water absorption properties. In application, the improved material may be used as furniture or decking for enhanced durability especially in conditions of high humidity.
