  Abstract

In the present research, mechanical properties, water absorption, and thermal stability of wood-poly(vinyl chloride)/low-density polyethylene (wood-PVC/LDPE) composite were improved via nanoclay addition. The presence of LDPE and Cloisite 30B at variable contents was studied. The composites were prepared by melt compounding and then compression molding. The morphology, mechanical, physical, and thermal properties of the composites were investigated. The micrographs of scanning electron microscopy (SEM) confirmed an appropriate coherence existing between lignocelluloses filler and PVC/LDPE matrix. The results revealed that the composite with 30 phr (parts per hundred) LDPE showed the best impact strength as 2887.33 kJ/m2. Besides, adding 3 phr nanoclay to the composite improved the impact strength by about 14 % and decreased the water absorption by 61 % compared to the PVC/wood composite. Also, the linear thermal expansion coefficient of the nanocomposite was 4.5
