合成聚丙酰胺-硫属半导体复合纳米材料的新技术

摘要

Polyacrylamide(PAM)-MS(M=Cd,Pb,Zn)nanocomposites were prepared by a convenient in situ polymerization-hydrolysis technique(SPH).The so-called SPH technique is based on the mechanism of the simultaneous polymerization of organic monomer and formation of semiconductor nanoparticles.It was found that the semiconductor nanoparticles were well homogeneously dispersed in the polymer matrices.This SPH technique may provide a new method for fabrication of other metal sulfide-polymer hybrid nanocomposites.%在水溶液体系中采用同步聚合-水解技术（Simultaneous Polymerization-Hydrolysis）制备聚丙烯酰胺-半导体纳米复合材料。该SPH技术是基于丙烯酰胺单体的聚合和MS(M=Cd,Pb,Zn)纳米粒子的形成同步发生，使生成的半导体纳米粒子可均匀分散在聚丙烯酰胺基质中。该技术还为制备其它有机聚合物-金属硫化物纳米复合物提供了一种新途径。
