【摘要】 采用sol-gel方法制备出了以钛酸正丁酯为无机前驱体,直接大红4B染料为有机小分子的有机/无机杂化热释电材料。对制得的杂化材料进行了红外、热性能、表面形貌、热释电等方面的性能分析。结果表明所制备的杂化材料热分解温度提高了近20℃、热释电系数较大,平均数值为1.05408×10-6C/cm2.K。更多还原

【Abstract】 In this paper the TBOT(tetrabutyl orthotitanate) was used as the inorganic precursor and congo red as the organic molecule. The organic/inorganic hybrid pyroelectric materials were prepared via the sol-gel process. The property characterization of the materials and films under the optimum condition was carried out, including the infrared, thermal TGA-DTA , surface properties and the pyroelectric properties ,etc. The result shows that the TiO2 hybrid films containing the modified congo red made by sol-gel process posses no phase separation, high thermal stability, and good pyroelectric property更多还原
