Abstract
The occurrence of grafting between WF and MTIR through esterification, the processing conditions for production of the composites, and the effect of MAH concentration on some physical and mechanical properties as well as the biodegradability of the composites have been studied. The FTIR measurement demonstrated that grafting through esterification had been attained between OH-groups of WF and acid anhydride groups of MTIR during kneading. The optimum kneading conditions for preparing the composites were 120 °C, 30 ∼ 90 rpm for 10 min. The tensile properties of the composites with WF based filler are greater than those with CS (corn starch) based filler. Addition of 10% of MTIR•10 and 8% MAH prepared using the two-step and one-step process, respectively to the TIR-WF composites gave the best result of tensile properties. The presence of MAH in the TIR-WF composites also improved the dimensional stabilization of the resulting composites. The tensile strengh of the composites prepared using the one-step process was about 90% of the composite prepared using the two-step process. The composites of TIR-WF with MTIR compatibilizer had slightly less resistance against subterranean termite (C. formasanus), brown-rot fungus (T. palustris), and white-rot fungus (C. versicolor) and slightly more resistance against bacteria (Bacillus sp.), within the experimental conditioned adopted.
