    Abstract: 本发明涉及涂料领域,公开了一种碳纳米管复合陶瓷网络改性水性不粘涂料的制备方法,包括:1)碳纳米管的预分散;2.1)将碳纳米管浆体与硅烷偶联剂反应,再与正硅酸四乙酯反应,得到陶瓷网络原位改性的碳纳米管;2.2)在碳纳米管表面包覆无定型氧化铝,再与正硅酸四乙酯反应,得到陶瓷网络原位改性的碳纳米管;3)将含氟乳液和正硅酸四乙酯预混合,再加入陶瓷网络原位改性的碳纳米管,升温搅拌反应后,加入其他组分。本发明方法可形成有机-无机的互穿网络结构,使得碳纳米管被锁定在该网络结构的孔隙中,并形成导电网络通道,对碳纳米管的性能影响小,可提升涂层的物理机械性能和防腐效果。

    Abstract: An electrically conductive adhesive composition, free of metals and metal salts comprising: - an adhesive component selected from the group consisting of polyethylene-vinyl acetate, elastomer polyolefins, polyvinyl butyral, polyacrylic acid, polyacrylates and poly(methyl methacrylate) in quantities of 5% to 40% by weight and - an electrically conductive component comprising acetylene or carbon black nanoparticles, carbon nanotubes and flakes or plates of graphene or graphene derivatives in quantities of 60 to 95% by weight, the percentages by weight being referred to 100 parts by weight of the adhesive component and electrically conductive component, wherein said electrically conductive component consists of: - acetylene or carbon black nanoparticies from 15 to 45% by weight, - carbon nanotubes from 5 to 25% by weight, and - flakes or plates of graphene or graphene derivatives from 35 to 70% by weight, the percentages by weight being referred to 100 parts by weight of said electrically conductive component, - a solvent compatible with the polymer component in quantities of 50% to 90% by weight referred to 100 parts of the composition consisting of polymer component, electrically conductive component and solvent. The adhesive composition is advantageously used in photovoltaic applications that require welding of components at low temperature and in power-supply or electronic applications that require the mechanical and electrical serial connection of electrodes in batteries, supercapacitors and multi-component electronic systems.
