摘要:
本文通过静电纺丝和喷涂工艺制备了含导电纤维网络的石墨烯(G)/热塑性聚氨酯(TPU)/聚二甲基硅氧烷(PDMS)导电复合材料,并对其拉伸敏感性能进行了详细研究。在拉伸应力场中,该导电复合材料具有大的断裂伸长率(165%)。随拉伸应变的增加,复合材料拉敏响应度先缓慢上升,当应变大于50%时,发生突变,整体表现出正的应变电阻响应行为。基于PDMS的封装作用,材料在循环应力场中表现出较弱的滞后效应和稳定的电阻响应行为。在电阻响应循环曲线中,复合材料在不同的应变幅度下均表现出良好的响应稳定性。本文报道的G/TPU/PDMS导电复合材料在柔性可穿戴电子设备领域具有良好的应用前景。
Abstract:
In this paper, the graphene (G) /thermoplastic polyurethane (TPU) /polydimethylsiloxane (PDMS) conductive polymer composites(CPCs) with conductive fibrous network s were prepared by the electrostatic spinning and spraying technology, and their strain sensing behaviors were studied in detail. The CPCs possess large elongation at break (165%). With the strain increasing , the sensitivity increases gently at first , and when the strain is greater than 50%, the sensitivity increases sharply, which shows a positive response between strain and sensitivity. Meanwhile, the CPCs exhibit weak hysteresis effect and stable resistance-strain sensing response behavior during the cyclic stretching, which is attributed to the encapsulation of PDMS . For the cyclic resistance-strain sensing curve s, the CPCs show good response stability under different strain amplitudes. The G/TPU/PDMS CPCs reported in this paper have brilliant application prospects in the field of flexible wearable electronics.
