摘要：
The nanocomposite of nano rice husk powder (nRHP)-ethylene propylene diene monomer (EPDM) was prepared from modified nRHP and EPDM with different formulations containing 0-100 parts of modified nRHP per 100 parts of EPDM using curing process and laboratory size two roll mill. The surface of nRHP was modified by grafting MA-g-EPDM copolymer on its surface to enhance the compatibility between nRHP and EPDM. MA-g-EPDM copolymer was successfully prepared by melt method. The effect of filler (nRHP) loading on the mechanical and morphological properties of the modified nRHP-EPDM nanocomposites was investigated compared to the unmodified nRHP-EPDM nanocomposites (blank). Successive study was carried out on the nRHP-EPDM nanocomposites by means of human gingival fibroblast (HGF) as a fine source of human cell lines to test the cytotoxicity of the prepared nanocomposites by using 3-(4,5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT). The in vitro study indicated that the prepared nanocomposites were non-toxic for HGF and could be developed for future medical uses. POLYM. COMPOS., 39:E500-E507, 2018.
