摘要
Abstract
As mcroelectronic devices often generate a lot of heat in the process of operation,improving the thermal conductivity of electronic packaging materials has become an urgent problem to be solved.Polymer materials are now the preferred substrates for electronic packaging materials,with the introduction of high thermal conductivity fillers effectively improving their thermal properties.However,it is still necessary to control the amount of filler to balance cost,process scalability,and product performance.In order to solve the above problems,submicron particles of ferroferric oxide(Fe3O4)are grown in situ on GNP by solvothermal method using graphene microsheets(GNP)as raw materials to obtain graphene-ferroferric oxide hybrids.The thermal GNP@Fe3O4/EP composites with vertical orientation of GNP@Fe3O4/EP are prepared by high temperature curing under magnetic field conditions after mixing the above hybrids as fillers with epoxy resin(EP).The thermal conductivity of the composites can reach 0.633 W/(m·K)when the filler content is 25wt%,which is 375%of the thermal conductivity of pure EP.This method effectively improves the thermal conductivity of epoxy resin matrix in the out-of-plane direction under low load.关键词
