Surface Modification of Carbon Fiber via Atom Transfer Radical Polymerization (ATRP)

Abstract:

This study demonstrates the surface modification of carbon fiber by grafting polyglycidyl methacrylate (PGMA) using atom transfer radical polymerization (ATRP). Firstly, the surface of carbon fiber was modified by using 3-aminopropyltriethoxysilane and 2-bromoisobutyryl bromide to immobilize ATRP initiators on the surface. Then the glycidyl methacrylate was initiated and propagated on the carbon fiber surface by ATRP. Characterization of these modified carbon fibers included Fourier transform infrared (FT-IR), Thermal gravimetric analysis (TGA) and 1H nuclear magnetic resonance (NMR). The results indicated that the grafting of PGMA from the carbon fiber surface was successful.
