Abstract:
A new kind of organic-inorganic hybrid nanomaterial Polymer/MS/SiO2(M=Pb,Cd) have been prepared by incorporating sol-gel process and hydrothermal crystallization technique. The as-prepared polymer matrix and Si-O network can successfully control the morphology of semiconductor nanoparticles and prevent aggregation. The existence of polymer can reinforce the thermal stability of composites. X-ray powder diffraction was used to characterize the nanoparticles, and transmission electron microscopy was used confirm that semiconductor nanoparticles were dispersed homogeneously in the silica and polymer matrix.

摘要:
采用溶胶-凝胶结合水热结晶技术,可成功把高聚物引入MS-SiO2网络结构,合成一种新型的有机-无机硫化物即Polymer/MS/SiO2(M=Pb,Cd)复合纳米材料,其中聚甲基丙烯酸甲酯或聚丙烯酰胺等高聚物的引入将有效地防止无机粒子团聚,控制粒子尺寸,前者还能形成核-壳结构复合粒子.作者还详细讨论了该复合纳米材料的热分析,结果表明,聚合物的存在提高了原有MS-SiO2(M=Pb,Cd)材料的热稳定性.
