Abstract

Titanium dioxide was prepared by Polymer Complex Solution Method(PCSM) according to the mole ratio of Titanium (IV) isopropoxide(TTIP)/solvent and polymer(Poly Ethylene Glycol). Polymer electrolytes were usually made by dispersing preproduced ceramic nanoparticles in a polymer matrix. Using this method, pure and nano-sized TiO_2 powder was synthesized through a simple procedure and polymer entrapment route. At the optimum amount of the polymer, the titanium ions are dispersed in solution and a homogeneous polymeric network is formed. The maximum intensity of anatase phase of TiO_2 was achieved by calcining at 500°C for 2h. The synthesized TiO_2 powders were nano-sized and the average size was about 50nm. Anatase/Rutile ratio of the synthesized TiO_2 was 70%/30%.
