摘要:

我们报道了一类新型的聚合物纳米复合材料,其由分散在聚合物基体中的有机纳米颗粒组成,粒径为30-120 nm。质子化聚(4-乙烯基吡啶)-r-聚丙烯腈与两亲性间胺黄染料分子在水溶液中通过静电相互作用自组装形成有机纳米粒子。一个强烈增宽的拉曼位移带被探测到,这表明存在增强的光电性能从聚合物纳米复合材料。本文以无规共聚物聚电解质和介晶两亲分子为设计的自组装结构单元,为有机纳米粒子的制备提供了一条新的途径。

英文摘要:

We report a novel class of polymer nanocomposite composed of organic nanoparticles dispersed in polymer matrix, with the particle sizes of 30-120 nm in radius. The organic nanoparticles were formed by the self-assembly of protonated poly(4-vinyl-pyridine)-r-poly(acrylonitrile) and amphiphilic metanil yellow dye molecules through electrostatic interactions in aqueous solution. A strongly broadened Raman shift band was probed, suggesting the presence of enhanced optoelectronic property from the polymer nanocomposite. Here, using random-copolymer polyelectrolytes and mesogenic amphiphiles as the designed building blocks for self-assembly, a new approach is acutally provided to fabricate organic nanoparticles.
