通过溶胶-凝胶法将硅烷染料dr1ASd、含硅氧烷PMMA和TEOS在酸催化条件下共水解-缩合制备了新型非线性光学杂化材料PMMA/SIO2/dr1,并运用fT-Ir、SEM、uV-VIS、dSC/Tg和uV-VIS等测试方法对其结构和性能进行表征。测试结果表明:杂化材料中有机相和无机相之间通过共价键结合,无相分离出现;杂化材料的玻璃化转变温度(Tg)和热分解温度(Td)分别达到165℃和405℃;电晕极化后杂化材料具有较高的生色团取向有序度(Ф=0.238),并表现出良好的取向稳定性,80℃条件下3H后依然有初始值的79%。A novel nonlinear optical(NLO) hybrid material PMMA/SiO2/DR1 was successfully prepared through hydrolysis and co-condensation of alkoxysilane dye(DR1ASD),polymethyl methacryate(PMMA) containing alkoxysilane,and tetraethoxysiliane(TEOS) together via sol-gel route.The structure and properties of the hybrid samples were characterized by fourier transform infrared spectra(FTIR),scanning electron microscopy(SEM),differential scanning calorimetry(DSC),thermogravimetric analysis(TG) and UV-vis spectra.The results showed that the organic phase was connected with inorganic phase by covalent bond without phase separation.The Tg and Td of hybrid material reached 165℃ and 405℃ obtained from DSC and TG curves respectively.High ordering parameter(Φ=0.238) of the hybrid material after corona poling was investigated by UV-vis spectra and the hybrid material exhibited excellent orientational stability as the Φ was able to maintain about 79% of its initial value at 80℃ for 3h
