In this study, microspherical poly(methyl methacrylate)/multi-walled carbon nanotube (PMMA/MWCNT) composites were successfully and directly prepared by in situ dispersion polymerization using poly(N-vinylpyrrolidone) in methanol. The 0.03 wt% of MWCNT on the PMMA microspheres having 5 μm of diameter and 100,000 g/mol of molecular weight with 11.2 % of the Cv (the coefficient of variation) were synthesized. With increase of the MWCNT content, the colors of the products changed from white to dark black. The morphology of synthesized composite was investigated by using scanning electron microscopy and transmission electron microscopy, and the experimental results demonstrated that MWCNT is well dispersed and embedded in the final PMMA/MWCNT composites. |
