A novel electrochemical processing for immobilization of functional fine particles on various substrates has been investigated. The particles were dispersed in electrolyte solutions with the precursors of binder materials, and then electrolyzed with the substrates as the cathode. Titania photocatalyst particles could be immobilized on stainless steel plates with electroplated copper or palladium and showed superior catalytic activities. Alumina particles were successfully incorporated into silica coatings that : were deposited from silica sol by electrolysis, and the composite films had good electrical insulation and wear resistance.It was also conducted that development of new precursor solutions which could be used in this process for the precipitation of the binder materials. Optimized silica sol for silicate precipitation, titanium trichloride solutions and peroxy-titanium solutions for titania, and peroxy-zirconium solutions for zirconia were found to be applicable to the process.

研究了一种新的电化学方法将功能性微粒固定在各种基底上。将颗粒分散在具有粘合剂材料的前体的电解质溶液中，然后以基底作为阴极电解。采用电镀铜或电镀钯的不锈钢板作为载体，可以将TiO2光催化剂颗粒固定在不锈钢板上，并显示出良好的上级催化活性。采用电解法从硅溶胶中沉积出SiO2涂层，并成功地将Al2O3颗粒引入到涂层中，得到了具有良好电绝缘性和耐磨性的复合膜，同时还开发了新的前驱体溶液，用于该过程中粘结剂材料的沉淀。优化的硅溶胶的硅酸盐沉淀，钛溶胶的解决方案和过氧钛解决方案的二氧化钛，和过氧锆解决方案的氧化锆被认为是适用于该过程。
