INFLUENCE OF N, N-DIMETHYLACETAMID ON THE THERMAL AND MECHANICAL PROPERTIES OF POLYMER-FILLED WOOD

Abstract

Mercerized wood species were impregnated with N, N-dimethylacetamid. The FT-IR showed enhanced absorption at 1419 cm-1(-C-/CH3), and the 1267 cm-1 (-N-/ CH3) stretching band confirmed the polymerization reaction. Differential scanning calorimetric analysis indicated that the decomposition temperature of polymer-filled wood gives a higher thermal stability compared to the raw material. Polymer-filled wood yielded higher MOE and MOR compared to the untreated wood. The Young’s modulus of Xylopia Spp Artocarpus Rigidus and Eugenia Spp were significantly different between raw wood and WPC. The increase in the stiffness and the thermal stability of the composites increased due to the crystallinity of polymer-filled wood as indicated by XRD analysis.
