主 题：graphene waterborne epoxy anticorrosion electrochemical property
摘 要：In this work,waterborne epoxy resin E44 and graphene were employed as the matrix and nanofiller,respectively,to construct composite coatings with enhanced anticorrosion *** pattern and TEM observation indicated that the obtained graphene had a stacked structure of few-layer graphitic sheets with numbers of *** observations revealed that no defects or microcracks existed on the surface of graphene/epoxy coatings and the internal micropores and microcracks were filled by *** spectra displayed that all the characteristic absorption peaks were attributed to the epoxy resin cured with *** Tafel polarization curves showed that,as the graphene addition amount increased,the corrosive potential increased and the corrosive current *** results proved that the addition of graphene into epoxy coatings could not only increase the impedance arc in Nyquist plots,but also increase the impedance modulus at low ***,the enhanced anticorrosion mechanism was proposed and discussed.
