| 摘 要： | 利用低温等离子体聚合的方法在超细ZrO2及SiC粉体表面聚合了聚乙烯、聚苯乙烯以及聚甲基丙烯酸甲酯等不同的聚合物层。透射电镜(TEM)、热重(TGA)及漫反射红外光谱的结果表明3nm～8nm厚的聚合物膜存在于超细陶瓷粉体的表面。经低温等离子体聚合处理过的ZrO2粉体在有机载体中的分散性显著提高。液体石蜡体系中，经低温等离子体聚合处理过的ZrO2粉体体系的粘度要远远小于未处理的ZrO2粉体体系。

| Abstract: | In order to prevent the agglomeration and improve the dispersion of ultrafine ceramic powders in liquid paraffin system etc. organic media, different kinds of polymer films were coated on the surface of ultrafine ZrO2 and SiC particles by low temperature plasma polymerization. The encapsulated powders were analyzed by TEM, TGA, and DRIFT. The results show that, the dispersion of plasma treated ZrO2 powders in the organic medium was better than that of untreated ZrO2 powders. The viscosity of liquid paraffin with same solid loading showed a significant difference between plasma treated and untreated ceramic powders. |
