摘要
采用紫外辐照法成功合成了ＣｄＳ－聚丙烯酰胺（ＣｄＳ－ＰＡＭ）、Ａｇ－聚丙烯酸胺（Ａｇ－ＰＡＭ）等无机－有机聚合物纳米复合材料。在紫外辐照过程中，无机相纳米粒子的生成和聚丙烯酰胺（ＡＭ）单体的有机聚合反应同步发生，使得生成的无机相纳米微粒均匀分散在有机聚合物基质中。实验发现，无机离子的存在可促进有机单体的聚合，而有机单体的聚合又可阻止无机相纳米粒子的团聚。这同时也为制备其它无机－有机聚合物纳米复合材料提供了一条有效的新途径。
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.
