摘　　要：将铈钛氧簇[Ti8O7(HOEt)(OEt)21Ce]和PEDOT低聚物的混合溶液通过滴涂–二次聚合成膜制得一种表面具有特殊纳米沟壑结构的无机/有机复合薄膜PEDOT:Ce@TiO2。PEDOT:Ce@TiO2具有很强的疏水性和对乙腈溶液较好的润湿性,能用作阴极电致变色材料和超级电容器电极材料。PEDOT:Ce@TiO2展现出较PEDOT薄膜更优良的电化学性能,在电流密度为1 A/g时,PEDOT:Ce@TiO2的质量比电容为71.2 F/g,是相同条件下PEDOT薄膜的质量比电容的1.7倍。采用PEDOT:Ce@TiO2进一步组装了全固态电致变色超级电容器原型器件,当充电完成时器件的变色区域呈现墨绿色,当放电完成时器件的变色区域呈现亮黄色。A new inorganic/organic composite film PEDOT:Ce@TiO2 was prepared through drop casting-secondary polymerization method using the mixture solution of PEDOT oligomer and cerium-containing polyoxotitanate cage[Ti8O7(HOEt)(OEt)21Ce].PEDOT:Ce@TiO2 exhibits a special nanostructure with gully-like rough surface,which shows strong hydrophobicity while good wettability to acetonitrile solution.PEDOT:Ce@TiO2 can be used as cathodically electrochromic film and supercapacitor electrode material.The mass specific capacitance of PEDOT:Ce@TiO2 is 71.2 F/g at a current density of 1 A/g,which is 1.7 times higher than that of the PEDOT film.An all-solid-state electrochromic supercapacitor prototype device was further assembled using PEDOT:[e-mail] charging completed the electrochromic area of this device shows dark green,and it turns bright yellow with discharging completed.
