摘要
As a widely used engineering polymer,epoxy resin has been successfully employed in high-performance components and setups.However,the poor thermal and friction properties of traditional epoxy resin greatly limit its application in many extreme environments.In this work,a new kind of epoxy-Ti3C2 with three-dimensional nanosheets(3DNS)composite which was designed by freeze-drying method showed up excellent thermal and friction properties.As a result,the coefficient of thermal expansion(CTE)of epoxy-Ti3C23DNS 3.0 composites was 41.9 ppm/K at 40℃,which was lower than that of the traditional epoxy resin(46.7 ppm/K),and the thermal conductivity(TC)was also improved from 0.176 to 0.262 W/(m-K).Meanwhile,epoxy-Ti3C23DNS 1.0 composites showed up the best friction property,with wear rate 76.3%lower than that of epoxy resin.This work is significant for the research of high-performance composite materials.
