This study aims to compare the resistance against subterranean termites of wood–polymer composites produced by in situ polymerization. The biological tests were carried out by choice and no-choice feeding tests. Poly (furfuryl alcohol), poly(styrene) and poly (methyl methacrylate) were studied here. They were impregnated into a Brazilian fast-growing pine wood using a vacuum:pressure method and then cured under simple heating. These treatments were evaluated using chemical (by infrared spectroscopy) and morphological (by scanning electron microscopy) analyses. The termite attack was evaluated by mass loss determination and photography. In general, all the treatments were effective in protecting the fast-growing pine wood. Results obtained by no-choice tests indicated that the treatment solution with 75% of furfuryl alcohol was less effective than the others, which indicates that both choice and no-choice tests may be important in a comprehensive study on the termites resistance of solid woods.

Wood Polymer Composite

A novel biomass composite, wood-polymer composite with potential good mechanical properties, durability and environmental characteristic capable of applying in fields of construction and traffic as structural material, was prepared by generating high-performance polymer from in situ polymerization of styrene in wood porous structure. The vinyl monomer, styrene, combing with 1wt% AIBN as an initiation, was first impregnated into wood porous structure under a vacuum/pressure condition, and then in situ polymerized through a thermal treatment. The structure of the resultant composite was characterized by SEM, FTIR and XRD. Results show that styrene polymerized into polystyrene through free radical polymerization, and the resultant polymer fully filled in wood porous structure in a column form, partly contacting wood matrix. FTIR analysis indicates that polystyrene generated into wood pores, indicating weak interaction between them. XRD analysis suggests that the polystyrene generated into wood pores mainly existed in an amorphous form.

Wood Polymer Composite

A novel Wood-Polymer Composite, Wood-PSt composite combining both advantages of wood and polystyrene was fabricated by determining the polymerization craft of monomer in wood porous structure through impregnating monomer into wood pores and followed by in-situ polymerization through a thermal-catalyst treatment. The performance was examined, and its structure was also characterized by SEM and FTIR. The results indicate that the optimum polymerizing craft is: 80oC, 8h and 3% AIBN. Under the optimum craft, the mechanical properties involving modulus of elasticity and compression strength were linearly increased with content of polystyrene. SEM and FTIR show that styrene polymerized under the employed polymerization craft, and the resultant polystyrene relatively full generated in wood cellular structure, in accordance with the results of the optimum polymerizing craft. Such composite having good mechanical properties and biomass features can be widely used in fields of construction, traffic and furniture.
