摘要:
以热塑性弹性体苯乙烯-乙烯-丁烯-苯乙烯和多壁碳纳米管导电浆料为原料,采用熔融涂覆法将混合溶液均匀涂覆在丁苯橡胶弹性布上制备电阻式应变带,探讨基于碳纳米管柔性应变传感器的应用,研究电阻式应变带的力学性能及传感性能。结果表明:在1 000次循环拉伸后,应变带具有较低的不可逆伸长率,且导电成分不影响弹性布的弹性; 应变在0～60%时灵敏度为1.5,应变在60%～100%时灵敏度为5; 电阻变化率迟滞性小于20%; 在不同应变下,应变带具有良好的曲线特征; 在40%应变循环下,应变带表现出良好的重复性和稳定性。研究结果有助于准确测量人体肘关节和呼吸运动,在智能服装和运动健身方面具有良好的应用价值。
Abstract:
In order to explore the research and application of flexible strain sensors based on carbon nanotubes, thermoplastic elastomer styrene-ethylene-butylene-styrene and multi-walled carbon nanotubes conductive paste were used as raw materials. Then a resistive strain band was prepared by uniformly coating the mixed solution on a styrene butadiene rubber elastic cloth by a melt coating method. The mechanical properties and sensing properties of the resistive strain band were studied. The results show that the strain band has a small irreversible elongation after 1 000 cycles of stretching, and the conductive composition does not affect the elasticity of the elastic cloth. The sensitivity is 1.5 between the strain of 0～60% and 5 between the strain of 60%～100%. The resistivity hysteresis is less than 20%. The strain band has good curve characteristics under different strains and shows good repeatability and stability under 40% strain cycle. The results help to accurately measure human elbow joints and respiratory movements, and possess good application value in smart clothing and sports fitness.
