Wood-Polymer Composite Prepared by Combined Two-Step Method and its Dimensional Stability
Wood-polymer composite was prepared by a novel combined two-step method with maleic anhydride (MAN) for the first treatment, and mixed monomers of glycidyl methacrylate (GMA)/ methyl methacrylate (MMA) (1:5 of molar ratio) for the second treatment. SEM and FTIR technologies were employed to characterize the interfacial compatibility between resultant polymer and wood matrix, and the dimensional stability of the resultant wood-polymer composite was also tested. The results indicated that polymers fully filled up wood cell lumina and chemically bonded to wood cell wall, resulting in the improvement of interfacial compatibility between polymer and wood matrix without obvious lacunae. The dimensional stability of poplar wood was significantly improved after the combined two-step treatment, and became more stable than that of PEG-1000 treated Poplar Wood.
