溶胶-凝胶法制备多孔TiO2薄膜的研究
Study on the Preparation of Porous Ti02 Film by Sol-Gel Method
摘要
Abstract
Porous TiO2 thin films deposited on glass substrates were prepared by sol-gel method. The influence of pH value, template agent and adding amount of ethanol on the properties of the sol and the porous film were studied. Experimental results show that in the process of sol-gel, the steady and trans- parent sol was obtained when pH=3 and polyethylene glycol-1000 was used as template agent, and the sol with the smallest particles and the least aggregation was obtained when n(PEG-1000)/n(Ti) was 0.05. The porous films with uniform structure and none cracking were prepared by the above sol. The in- tegrity film was formed from the sol with n(CH3CH2OH)/n(Ti)=24 : 1, with the decomposition of poly- ethylene glycol and the escaping of CO2 and H20 during sintering, the integrity orderly porous TiO2 film with many tiny pores was prepared.关键词
