摘　　要：以石墨烯粉体为填料,环氧E-44为基料研制了一种环氧复合防腐导电涂料,对比了不同石墨烯含量的复合涂料与纯环氧涂料、炭黑环氧涂料、环氧富锌涂料、玻璃鳞片涂料的导电和防腐等方面的性能。结果表明:石墨烯用量为0.5%时,涂层防腐性能优良,用量为1%时,涂层表面电阻率为106Ω,符合导静电要求。Conductive anticorrosive coatings using graphene as fillers in epoxy resin （E- 44） are prepared. The performance of graphene/epoxy coatings is compared with pure epoxy coatings, carbon black/epoxy coating, commercial zinc-rich epoxy coatings and glass flake/ epoxy coatings. The results reveal that a low addition of 0. 5% graphene can improve the an- ticorrosion performance of epoxy coatings and the addition of 1% graphene can enable the coating to show good anticorrosive and conductive performance, with its surface resistance approx. 10^6Ω, which can meet the requirement of antistatic coatings.
