Surface modification of vapor-grown carbon nanofibers in radio frequency plasma

摘要：

Vapor-grown carbon nanofibers (VGCNFs) were treated in radio frequency (RF) plasma to activate their surface and thus to improve the compatibility with the matrix in polymer composites. The surface of VGCNFs were modified in the atmosphere containing different ratio of O2 and Ar. FT-IR and TG measurement shows that when O2 content in mixture gases was 5％, -C-O and -O-H functional groups were produced greatly in the surface of VGCNFs. With O2 content increased to 8％, most surface of carbon fibers was severely oxidized, resulting in defected structures of the inner layers of VGCNFs.
