We report herein a simple method for attaching vinyl groups onto the sidewalls of carbon nanotubes (CNTs) and the application of vinyl–carbon nanotubes (CNT–CC) in fabricating polymer composites. The synthesis of CNT–CC was monitored with IR spectroscopy, Raman spectroscopy, and thermogravimetric analysis. The obtained CNT–CC showed good compatibility with the in situ polymerization of poly(methyl methacrylate) (PMMA) and exhibited no tendency for phase separation in the final composite. A transmission electron microscopy study revealed a uniform coating on the CNT–CC tubes, indicating good grafting efficiency of PMMA. The uniform dielectric PMMA coating was responsible for the lower electrical conductivity of the CNT–CC/PMMA composites versus that of the CNTs without vinyl modification. © 2008 Wiley Periodicals, Inc.
