水热法制备Al2O3@ZnO颗粒微观形貌及其对环氧树脂基复合材料导热性能的影响
Influence of microstructure of Al2O3@ZnO on thermal conductivity of epoxy resin composite by hydrothermal method
摘要
Abstract
ZnO was coated on the surface of Al2O3 by hydrothermal method to prepare Al2O3@ZnO while different microstructures of ZnO coating layer grew on it by controlling the synthesis conditions. This paper focused on the pH in the growth solution which had a great influence on the coating results and microstructure of ZnO coating layer, then the thermal conductivity of epoxy resin filled with Al2O3@ZnO was studied. The research results show that with the increase of pH, the homogeneity and compactness of the coating layer is better which mean the coating effects of ZnO on Al2O3 are better. The microstructure of ZnO on the surface of Al2O3@ZnO changes from globular to starlike and then hedgehog-like, meanwhile, the thermal conductivity of epoxy resin filled with Al2O3@ZnO is also improved and the result is best when the pH is 10, which is 10.3% better than that of the epoxy resin filled with untreated Al2O3.关键词
