Study on the properties of nanocomposite based on high density polyethylene, polypropylene, polyvinyl chloride and wood

Montmorillonite (MMT) was modified by cetyl trimethyl ammonium bromide (CTAB) and verified by X-ray diffractometer. Wood polymer composite (WPC) was prepared by solution blending of high density polyethylene (HDPE), polypropylene (PP), polyvinyl chloride (PVC), wood flour, modified MMT and glycidyl methacrylate (GMA). The composites were characterized by transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). Mechanical properties of modified MMT treated WPC were found better compared to either WPC or unmodified MMT treated WPC. Thermal stability, flammability, hardness and water absorption values of WPCs were improved due to inclusion of modified MMT to WPC.
