Characterization of Wood-Polymer Composite Fabricated by Polymerization of Methyl Methacrylate and Styrene within Wood
Abstract:
The fast-growing poplar wood, Populus ussuriensis Kom, was prepared into wood-polymer composite by the in-situ polymerization of methyl methacrylate (MMA) and styrene (St) under vacuum/pressure and subsequent catalyst-thermal conditions. SEM observation, FTIR, XRD and DMA analysis indicated that the resulted polymer well filled up wood cell lumen in an amorphous form and physically reinforce wood matrix, which resulted in the improvement of glass transition temperature and storage modulus of wood. Such method could endow low-quality wood with potential value-added applications.
