摘要: 采用Sol-Gel技术制备了二乙醇胺/有机硅杂化涂料, 并用FTIR、UV-Vis、AFM、TGA及接触角等测试技术对涂料及其涂层进行了分析表征. 结果表明, 该杂化涂料具有良好的成膜性. 由于膜层中存在大量的亲水性羟基基团, 使膜层具有良好的亲水性能和防雾效果. 固化后的聚合物膜层中无机相形成了三维交联网络, 赋予了膜层优异的耐磨性和热稳定性.

Abstract: The TEOS-derived silica was modified with epoxy by copolymerization of TEOS with GPTMS. The epoxy sites have become anchors for cross-linking the nanoparticles of the skeletal backbone of the silica hybrids by attachment of DEA. The synthesis material was determined by FTIR, TGA and AFM . The hybrids have an excellent film-forming capability and possess a high thermstability. After addition of DEA, the inorganic-organic hybrid system containing abundant —OH group has a wettable surface and long antifogging time. The contact angles of the hybrid film for water were less than 31° and the coating meet the requirements for transparence. The existing silica gel network improved the scratch property. So the coating have an exce-llent mechanical property.
