以氟碳树脂为基体,炭黑和石墨烯为导电填料,加上适量的助剂,共混制备了一种新型导电油墨并测试其导电性能和力学性能。借助电阻测试、万能试验机力学测试、铅笔硬度测试等分析手段,探讨了炭黑和石墨烯导电填料的添加量对导电油墨导电性能和力学性能的影响。结果表明:当炭黑和石墨烯用量分别为10%(wt,质量分数,下同)和7%时的混合导电填料制备的氟碳树脂基碳浆导电油墨性能最优,体积电阻率为0.28Ω·cm;当炭黑和石墨烯用量分别为10%和5%时,导电油墨材料的力学性能最好,拉伸强度达到14.3MPa,断裂伸长率达为192.7%。
Fluorocarbon resin was used as matrix,carbon black and graphene as conductive filler,a proper amount of additives then was added,after mixture,a new type of conductive ink was made.Also its electrical conductivity and mechanical property were tested.With the aid of resistance test,mechanical test of universal testing machine,pencil hardness test and other analytical methods,the effects of adding carbon black and graphene conductive filler on the conductive and mechanical properties were discussed.The results showed that when the used carbon black and graphene were 10% and 7%,the performance of conductive ink used fluorocarbon resin prepared by mixed conductive filler achieved the optimal.Volume resistivity was 0.28Ω·cm.When the carbon black and graphite were 10% and 5%,the ink had the best mechanical property,the tensile strength was 14.3MPa,the elongation after fracture was 192.7%.
