초록/요약
Multi-walled carbon nanotube (MWNT) nanocomposites with poly(methyl methacrylate) were prepared via both an in situ bulkpolymerization and a suspension polymerization using a radical initiator of 2,2-azobisisobutyronitrile (AIBN). Prior to the syn-thesis, the MWNT was puried in an acidic solution to remove impurities such as metallic catalysts and amorphous carbons. TheAIBN induced PMMA was grafted on the MWNT, which was conrmed by a Fourier transform infrared spectrometer (FT-IR).The composite morphology of the MWNT was observed by scanning electron microscopy (SEM). Electrical characteristics werefurther examined via both a four-probe method and a rotational rheometer equipped with a high voltage generator..
