Hydrophilic coatings are realized by controlling the surface texture and chemistry using organic surfactants, polyelectrolytes and hydrogels. At here, we present SiO2-TiO2 based hydrophilic systems with ordered mesoporous structure was synthesized by a binary sol-gel reaction of TEOS-TiCl4 and the subsequent sulfonation by adopting a simple chelating chemistry between the catecholic group and surface Ti ion. Moreover, the hybrid resins consisting of PEG and a silane coupling agent exhibited the controlled wettability, excellent processibility, then extended to various applications such as acid catalyst SiO2-TiO2-SO3H, specific bioadsorption to fibrinogen protein, pathogen bacteria and HEp-2 cell and high temperature fuel cell membrane. In addition, we have used polysilazane, polycarbosilane, the derivatives and fluoropolymer to fabricate various functional 3D micro- and nano-structures, mainly for microfluidic device applications via lithographic techniques. |
