摘　　要：三维(3D)打印是导电高分子材料的一种简单快捷的加工技术。以柔性热塑性弹性体(TPE)材料为基材,添加Cu粉作为导电介质,然后通过挤出成型制备一系列Cu/TPE复合材料,最后3D打印试样。测试Cu/TPE复合材料的微观结构以及拉伸和导电性能。结果表明,10%150目Cu/TPE试样的拉伸强度和断裂伸长率均达到最高值,分别是27.30 MPa和1152.08%,比纯的TPE材料分别提高13%和14%。20%的Cu粉制备的Cu/TPE可实现3D打印制造,但由于材料中Cu粉分布的不连续性,所制备的材料尚不具备导电性。Three dimensional(3D)printing technology about conductive polymer materials was a very simple and fast manufacturing technology.Thermoplastic elastomer(TPE)material was used as flexible substrate materials,and Cu powder was used as conductive additives.The Cu/TPE composites were prepared by extrusion and then by 3D printing.The microstructure,tensile and conductivity properties of Cu/TPE composites were tested.The test results show when Cu is 10%and 150 mesh,the tensile strength and breaking elongation rate of Cu/TPE samples could reach 27.30 MPa and 1152.08%,respectively.Comparing with pure TPE materials,the tensile strength and breaking elongation rate are improved 13%and 14%,respectively.The Cu/TPE materials added with 20%Cu powder could be used for 3D printing manufacturing,but it has not conductivity due to the discontinuous distribution of Cu powder in the material.
