    摘要:

    采用紫外輻照法成功合成了CdS-聚丙烯酰胺(CdS-PAM)、Ag-聚丙烯酰胺(Ag-PAM)等無機-有機聚合物、納米復(fù)合材料。在紫外輻射過程中,無機相納米粒子的生成和聚丙烯酰胺(AM)單體的有機聚合反應(yīng)同步發(fā)生。使得生成的無機相納米微粒均勻分散在有機聚合物基質(zhì)中,實驗發(fā)現(xiàn),無機離子的存在可促進(jìn)有機單體的聚合,而有機單體的聚合又可阻止無機相納米粒子的團聚,這同時為制備其它無機-有機聚合物納米復(fù)合材料提供了一條有效的新途徑。

    Abstract:

    Inorganic (CdS, Ag ) - polyacrylamide (PAM ) nanocomposites were prepared successfully using a convenient ultraviolet irradiation technique. It was found that the inorganic nanoparticles could be well homogeneously dispersed in the polymer matrices as the result from the fact that polymerization of organic monomer and formation of inorganic nanoparticles were simultaneous. It is very interesting that the presence of inorganic ions may be favorable for the Polylnerization of organic monomer, meanwhile the organic polymer matrices can efficiently prevent producing inorganic nanoparticles from aggregation. This technique is also applied to the fabrication of other inorganic-polymer hybrid nanocomposites.
