摘　　要：以环氧树脂(Epoxy)为基材、碳化钛(Ti_(3)C_(2)T_(x))为填料,通过溶液共混的方法制备复合材料。采用扫描电子显微镜(SEM)、X射线衍射(XRD)、红外光谱仪(FT-IR)表征材料的微观结构,采用同步热分析仪、激光导热仪测量复合材料的热学性能,采用阻抗分析仪测量复合材料的电学性能。结果表明,Ti_(3)C_(2)T_(x)填料质量分数为30%时,Ti_(3)C_(2)T_(x)/Epoxy复合材料的热导率达到0.414 W/(m·K),相较纯环氧树脂提高了 2.27倍。随着Ti_(3)C_(2)T_(x)含量的增加,复合材料的介电常数和介电损耗也有所增加。Ti_(3)C_(2)T_(x)/Epoxy composites were prepared by solution mixing and in-situ polymerization.Scanning Electron Microscopy(SEM),X-Ray Diffraction(XRD)and Fourier Transform Infrared(FT-IR)were used to characterize the material.Both thermal and dielectric properties of the composites were measured.The results showed that the thermal conductivity of Ti_(3)C_(2)T_(x)/epoxy composite reached 0.414 W/(m-K)for filler content of 30%(wt),2.3 times of that of pure epoxy resin.Besides,the dielectric permittivity and dielectric loss of the composite improved with the increase of Ti_(3)C_(2)T_(x) filler content.
