聚合物/Al2O3导热绝缘复合材料研究进展

摘要

Alumina is a kind of important heat conductive filler to prepare high thermal conductive composites due to its low price and excellent comprehensive properties,such as superior electrical insulation and high thermal conductivity. In this paper,the authors discussed the research progress in insulting thermal conductive polymer/alumina composites,the influences of content,shape,particle size and surface modification of alumina,hybrid fillers and processing methods,etc. on the thermal conductivity and other properties were emphasized to supply references for preparing polymer/alumina composites with good comprehensive properties.%Al2O3以其优越电绝缘性及良好导热能力、价格低廉等综合性能成为目前制备导热绝缘复合材料的一类重要填料.综述了聚合物/Al2O3导热绝缘复合材料的研究进展,重点阐述了氧化铝的用量、形状、粒径、表面改性、混杂填充及加工方法等对聚合物/Al2O3复合材料热导率及其他性能的影响,为制备综合性能优良的聚合物/Al2O3复合材料提供有益参考.
