In this work, various chain length of SAN was synthesized onto the surface of MWCNT via atomic transfer radical polymerization (ATRP) to investigate the compatibility of MWCNT with polycarbonate (PC). Fourier transform infrared spectroscopy (FT-IR) and thermogravimetric analysis (TGA) were used to characterize SAN-g-MWCNT. 20%, 50% and 80% weight loss of SAN-g-MWCNT can be obtained by controlling reaction period and it is designated as SAN20-g-MWCNT, SAN50-g-MWCNT and SAN80-g-MWCNT, respectively. PC/MWCNT nanocomposites were prepared by melt blending and various properties, such as mechanical, rheological and electrical properties, are measured. Effect of functionalization of MWCNT on the dispersion state of MWCNTs was investigated through rheological and morphological analysis. |
