摘要：

The new roles of organic compounds in chemical processes for ceramic coatings are confirmed in this study. Organic compounds remained in a fixed position in the coating, which was prepared from the chemically-modified titanium tetraisopropoxide solution and heated at temperatures as high as 673 K. It was not until the organic compounds decomposed to carbon dioxide and the gas phase was left from the coating that the nanostructure, consisting of nano-sized pores and anatase crystallites with preferred orientation, developed at 723 K.
