摘要
具有较大检测区域的纤维状柔性导电材料是可穿戴电子产品和电子纺织品等多种柔性器件的重要组成部分。通过在氨纶复丝表面涂覆碳纳米管(CNT)/RGO导电层,继而在导电层外部涂覆弹性聚氨酯(TPU)保护层来制备夹心结构的高度可拉伸和高灵敏度的柔性导电纤维。1D CNT和2D RGO组成的多维导电网络使纤维在具有较大可拉伸性的同时又拥有较大的相对电阻变化(ΔR/R0),将其用作传感器可用工作范围达465%(GF为215.0)。在与皮肤连接的可穿戴设备领域中具有广阔的应用前景。
A fibrous flexible conductive material with a large detection area is an important part of various flexible devices such as wearable electronic products and electronic textiles.Herein,a highly stretchable and sensitive flexible conductive fiber with a sandwich structure is prepared through coating a carbon nanotube(CNT)/RGO conductive layer on the surface of spandex multifilament,and then coating an elastic polyurethane(TPU)protective layer on the outside of the conductive layer.The multi-dimensional conductive network composed of 1D CNT and 2D RGO makes the fiber have a large tensile property and a large relative resistance change(ΔR/R0),it can be used as a sensor with a usable working range of 465%(GF is 215.0).It has broad application prospects in the field of wearable devices connected to the skin.
