Summary Carbon fibers were found capable of initiating the cationic polymerization of N-vinylcarbazole (NVC) at 60∼80°C. The activation energy of the polymerization was estimated to be 13.4 kcal/mol. The carbon fiber lost the initiating activity of the polymerization upon the blocking of carboxyl groups on the surface by the treatment with potassium bicarbonate or diazomethane. Therefore, it was concluded that carboxyl groups on carbon fiber play an important role in the initiation of the polymerization. Furthermore, it was found that during the polymerization, poly-NVC was grafted onto the surface; the grafting ratio was determined to be 39.7% (60°C, 24 h).
