Abstract

A new method for the production of nanocomposites, composed of gold nanoparticles (AuNPs) and (vinylbenzyl)trimethylammonium chloride--,-methylene bisacrylamide (VBTAC--MBA) hydrogel, is described. Raw-AuNPs of defined optical and granulometric properties were synthesized using direct current atmospheric pressure glow discharge (dc-APGD) generated in contact with a solution of HAuCl₄. Different approaches to the polymerization-driven synthesis of Au/VBTAC--MBA nanocomposites were tested. It was established that homogenous dispersion of AuNPs in this new nanomaterial with was achieved in the presence of NaOH in the reaction mixture. The new nanocomposite was found to have excellent heat-transfer properties.

摘要

本文描述了一种制备纳米复合材料的新方法，该复合材料由金纳米颗粒（AuNPs）和（乙烯基苄基）三甲基氯化铵-亚甲基双丙烯酰胺（VBTAC-MBA）水凝胶组成。使用与HAuCl₄溶液接触产生的直流大气压辉光放电（dc-APGD）合成了具有确定光学和粒度特性的原始AuNPs。测试了不同的聚合驱动合成Au/VBTAC-MBA纳米复合材料的方法。结果表明，在反应混合物中存在NaOH的情况下，AuNPs在这种新型纳米材料中实现了均匀分散。发现这种新型纳米复合材料具有优异的传热性能。
