二茂铁表面活性剂在聚丙烯腈基炭纤维表面的可逆修饰
Reversible surface modification of PAN-based carbon fibers by a ferrocene-based surfactant
摘要
Abstract
The surface of carbon fibers(CFs)was modified by a surfactant(ferrocenemethyl)dodecyldimethylammonium brom-ide(FDDA)to enhance the interfacial ashesion between the CFs and surrounding matrix.Results showed that it could be electro-chemically desorbed by a potentiostatic electro-oxidation method.The FDDA adsorption isotherm was attributed to the formation of multi-molecular layers mainly by non-electrostatic interactions.The adsorption and desorption of FDDA on the CFs have little effect on their tensile strength.The effects of FDDA modification on the interfacial properties of CF/epoxy composites were evaluated by a single-filament fragmentation test.Compared with the un-modified CFs,the FDDA-modified ones had significantly improved inter-facial adhesion properties in the composites.This method provides a potential approach for preparing recyclable CF/resin compos-ites.关键词
