| Abstract | This research aimed to investigate the formation of thin porous TiO2 film prepared by sol-gel process with spin coating. Poly(ethylene glycol) with molecular weight of 6,000 g/mol (6kPEG) was used as a pore generating agent. The TiO2 film was calcinated at 450?C for 1 hour. at different heating rates, 1, 5 and 10?C/min. It was found that the heating rate strongly affectedthe morphology of TiO2 film due to grain coalescence as grain coarsening and increase in pore size was found at lower heating rate. At higher heating rate, film density increased due to lower number of pores. On the other hand, for dense TiO2 film without poly(ethylene glycol) (noPEG), the heating rate did not affect on film morphology. |
