摘要
柔性电子器件由于其稳定、高导电性和高拉伸性等特点而受到广泛的关注。本文制备了一种由热塑性聚氨酯(TPU)线和铜(Cu)丝组成的双螺旋柔性导体(DHFC),导体初始电导率为5.71×10^(7) S/m。通过增大螺旋直径,使其拉伸性能增加,DHFC可恢复的最大形变量可达6706%。在弹性应变范围内,DHFC在重复形变(1000次循环的拉伸,应变为2200%)下表现出较高的稳定性,电阻的增加可以忽略不计。此外,由于导体外部涂有水性聚氨酯(WPU)而使其具有优异的防水性能,在水中所测的电阻值与在空气环境中所测的电阻值基本一致。
Flexible electronic devices are widely interested because of its stability,high conductivity,and great stretchability.A double-helix flexible conductor(DHFC)composed of thermoplastic polyurethane(TPU)and copper(Cu)wire is fabricated,the initial conductivity of the conductor is 5.71×10^(7)S/m.By increasing the helical diameter,tensile performance is increased,the maximum strain of the DHFC can reach 6706%.In the elastic strain range,DHFC shows high stability at repeated deformation(1000 cycles of stretching with a strain of 2200%)with a negligible increasing in resistance.In addition,due to the conductor is coated with waterborne polyurethane(WPU),it has excellent waterproof performance,and the resistance value measured in the water is basically the same as that measured in the air environment.
