Novel polyurethane thiazole(PUT)/SiO2 nanocomposite material was prepared by hydrolysis and condensation of alkoxysilane dye, polyurethane (PU) containing alkoxysilane, and tetraethoxysiliane (TEOS) together using the sol-gel process. The structure and properties were characterized by IR, SEM, TEM, UV-Vis, and DSC-TGA measurements. The result showed that the organic phase connected with the inorganic phase by covalent bond without separation of phase in the material, and the content of thiazole chromophore with od nonlinearity in the material, the glassy temperature, and decomposed temperature of the material increase remarkably; thus, the material can be used to manufacture second-order nonlinear apparatus having fine performance.
