MICROSTRUCTURE AND CRYSTALLOGRAPHIC ORIENTATION OF ANATASE COATINGS PRODUCED FROM CHEMICALLY-MODIFIED TITANIUM TETRAISOPROPOXIDE

Poly(ethylene glycol) was coordinated to a structure formed by the con trolled hydrolysis and polycondensation reactions of titanium tetraiso propoxide 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 prefer red orientation along the c-axis were prepared on quartz-glass plates by a dip coating method, In contrast, anatase coatings consisting of s ubmicrometer-sized pores and randomly orientated grains mere prepared from the solution in which the poly(ethylene glycol) had been isolated .
