摘要

The use of natural fibers and nanoclay as reinforcement materials in composites has proved the ability of providing several environmental and economical advantages. In this work, two groups of rice straw fibers (RSF) reinforced high density polyethylene (HDPE) nanocomposites were prepared in the presence of 3wt% maleated polyethylene (MAPE) as coupling agent. To the former group, nanomontmorillonite clay (n-MMT) was added after being treated with cetyltrimethyl ammonium bromide (CTAB), in order to enhance dispersiability, compatibility and interfacial bonding with the polymer. Calcium oxide (CaO) was added as a filler to the second group in fine powder form. These groups have been examined with regard to their mechanical properties and thermal stability. The interfacial adhesion has been also investigated by scanning electron microscopy(SEM). Results revealed that, significant improvement was attained for mechanical properties as the modified nanoclay %increases to similar to 2.5%. Maximum loaded amount of ca.10% CaO has found to be sufficiently required to enhance tensile strength with reasonable flexural strength.
