摘要

The use of radiation technique to process nanostructured materials or to produce nanostructured materials have been shown technically superior as alternative and viable techniques for further commercial exploitation. Research on radiation processing of nanocomposites have been initiated at the Radiation Processing Technology Division of MINT in the past three years. The main focus of this research is to utilize indigenous natural polymer for production of nanocomposites material. Natural rubber/clay composites and thermoplastic natural rubber/clay composites are the important materials that under studied. The natural rubber used in this work is of grade SMRL (Standard Malaysian Rubber) and the clay used was sodium montmorillonite modified with various types of cationic surfactants in order to make the galleries hydrophobic and thus more compatible with the elastomer. The natural rubber/clay nanocomposites were prepared by melt mixing. The compound was then irradiated using electron beam at optimum dose of 250 kGy. X-ray diffraction results indicated intercalation of the natural rubber into silicate interlayer. Upon irradiation at 250 kGy, the tensile strength of the NR/Na-MMT nanocomposites constantly reduced slightly with increasing clay loading, whereas the tensile strengths of NR/DDA-MMT and NR/ODA-MMT increases to optimum levels, 12.1 MPa and 9.5 MPa respectively at 3 phr clay contents. On the other hand, the elongation of NR/DDA-MMT nanocomposites is less affected with increasing clay content up to 3 phr.
