Abstract

Epoxy resins are chemically attached to carbon nanotubes (CNTs), in a one-step process in which a reaction mixture comprising the epoxy polymer, the CNTs and a bridging agent which is a chemical compound capable of forming living polymers, e.g. styrene or MMA is formed and radical formation is initiated in the reaction mixture; the epoxy polymer or monomer grafts onto the CNTs through the intermediary block of the bridging agent.
