Carbon fibers modified with silicone peroxide containing vinyl groups for silicone rubber reinforcement

A silicone peroxide, tris(tert-butyldioxy)-vinyl-silane (VTPS), was adopted for carbon fibers (CFs) surface modification to improve the mechanical properties of CFs reinforced polydimethylsiloxanes (PDMS) composites. FT-IR and XPS confirmed that the Si-CH=CH2 groups, which could generate covalent bonds between CFs and PDMS, were chemically bonded to CFs surface. And the method gave no obvious damage to CFs as shown by SEM and tensile strength...
