Microstructure and crystallographic orientation of anatase coatings produced from chemically modified titanium tetraisopropoxide

Poly(ethylene glycol) was coordinated to a structure formed by the controlled hydrolysis and polycondensation reactions of titanium tetraisopropoxide chelated with diethanolamine, From the resulting chemically modified precursor solution, anatase coatings consisting of nanometer-sized pores and grains with diameters of similar to 30 nm and a preferred orientation along the c-axis were prepared on quartz-glass plates by a dip coating method, In contrast, anatase coatings consisting of submicrometer-sized pores and randomly orientated grains mere prepared from the solution in which the poly(ethylene glycol) had been isolated.
