摘要
纸基柔性传感器应用前景广阔,但其力学性能有待增强,易受到高湿度或水汽的影响,限制了其实际应用.本研究以环氧大豆油(ESO)和衣康酸(IA)为原料制备β-羟基酯动态聚合物预聚物,通过溶液浸渍法将其与MXene纸基传感材料复合,得到复合纸基柔性传感器.传感器的性能研究结果表明,所得到的复合纸基柔性传感器的力学性能显著增强,作为应变传感器灵敏度较高,应变指数GF=8.5,响应时间0.41s,稳定循环工作超过1000次.在90%湿度条件下放置24h,输出性能不受影响,表现出较强的耐水性.该传感器可用于人体手指、手腕等关节的运动监测,也可以用于包装运输过程中的受力监测,包括撞击、侧翻等.以上结果表明,该复合纸基柔性传感器在可穿戴设备、人机交互、智能包装等领域有广泛的应用前景.
Abstract
Paper-based flexible sensors have shown great potential for a wide range of applications.However,their practical use is currently limited due to their mechanical properties needing improvement and susceptibility to high humidity or water vapor.In this work,a composite paper-based flexible sensor was prepared by solution impregnation method to combine MXene paper-based sensing material with a hydroxyl-ester dynamic polymer prepolymer derived from Epoxidized soya bean oil and Itaconic acid.The results demonstrated a significant enhancement in the mechanical properties of the composite paper-based flexible sensor.As a strain sensor,it exhibited high sensitivity(GF=8.5),fast response time(0.41s),and excellent cycle stability(>1000 cycles).Moreover,even after being exposed to 90%humidity for 24 hours,the output performance remained unaffected,indicating strong water resistance.This sensor shows promise for monitoring human joint movements such as fingers and wrists,as well as force measurements during packaging and transportation,including impacts and rollovers.The findings suggest that the composite paper-based flexible sensor has extensive potential applications in wearable devices,human-computer interaction,intelligent packaging,and other related fields.
