Abstract:   The multi-walled carbon nanotubes（MWNTs）was treated by acid oxidation，and then processed by acyl chlorination. The carbonyl chlorides groups reaction with epoxy acrylic acid resin was applied to get carbon nanotubes grafted epoxy resin，and then free radical polymerization is conducted with acrylic acid. Consequently，the waterborne epoxy acrylate resin grafted with carbon nanotubes is obtained. The resin as main film-former is used to prepare waterborne carbon nanotubes grafted epoxy acrylic resin coating. The structure of the resin is analyzed by IR. Results show that carbon nanotubes can be grafted with epoxy resin by introducing carbonyl chlorides groups.
