| Abstract: | In this paper the tetrabutyl orthotitanate(TBOT) was used as the inorganic precursor and congo red as the organic molecules.The organic-inorganic compound pyroelectric materials were prepared via the sol-gel process.The manufacturing technology of the hybrid materials was investigated and the optimum condition was also presented,the relevant property characterization of the materials and films under the optimum condition was carried out.The result shows that the TiO2 hybrid films containing the congo red made by sol-gel process possesses good pyroelectric property. |
