以PEO-PS-PEO三嵌段共聚物为模板剂，采用良-贫溶剂对诱导相分离和溶胶-凝胶化学方法制备了大孔TiO 2薄膜。大孔TiO 2在高达至少1000 °C下表现出不寻常的热结构稳定性。
Macroporous crystalline TiO2thin film is achieved by using an amphiphilic triblock copolymer of PEO-PS-PEO as a templating agent, coupled with a good-poor solvent pair induced phase separation process and sol−gel chemistry. The macroporus TiO2exhibits unusual thermal structural stability up to at least 1000 °C.
