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。 Using sol-gel combined with hydrothermal crystallization technology, polymer can be successfully introduced into MS-SiO2 network structure to synthesize a new type of organic-inorganic sulfide polymer / MS / SiO2 (M = Pb, Cd) , Of which polymethylmethacrylate or polyacrylamide and other polymers will effectively prevent the agglomeration of inorganic particles to control particle size, the former can form core-shell structure composite particles. The author also discussed in detail the thermal analysis of the composite nanomaterials. The results show that the presence of the polymer improves the thermal stability of the original MS-SiO2 (M = Pb, Cd) material.
