摘　　要：功能高分子材料通常都制成薄膜,薄膜状的功能高分子材料的导电性测量需要采用直流三电极、惠斯通电桥法和直流四探针法,但这些方法都对样品的尺寸和厚度有一定要求。不同厚度下直流电流的流向和分布不可控会严重影响测试精度,而且使用四探针法测量薄膜材料比较繁琐,需要先制备方形膜并将其平整地固定在水平玻璃板上。对此,通过上述方法了解,提出一种原创的测量装置,通过接触分离式TENG搭建了一套测量功能Ecoflex薄膜材料的导电性测量装置。并使用静电检测仪进行数据提取,平均相对误差为9.272%,填补了Ecoflex材料导电性测量的空缺。该Ecoflex薄膜材料的导电性测量装置的创新型在于接触分离式TENG测量功能Ecoflex薄膜导电性的优点在于基于位移电流的交流测试对样品的几何尺寸无严格要求,而且无需特定形状,操作方便,可原位检测。除此之外,提供了一种足底能量收集方案,可以用于机械能对电能的转化。Functional polymer materials are usually made of thin films,and the conductivity measurement of thin-film functional polymer materials requires DC three-electrode,Wheatstone bridge and DC four-probe methods,but these methods have certain requirements on the size and thickness of the sample.The flow direction and distribution of DC current under different thicknesses are not controllable,which will seriously affect the test accuracy.Moreover,the four-probe method is complicated to measure thin film materials,and it is necessary to prepare square film first and fix it flat on the horizontal glass plate.Based on the above methods,an original measuring device is proposed,and a set of measuring device for measuring the electrical conductivity of functional Ecoflex thin film materials is constructed by using the contact separation TENG.The average relative error is 9.272%,which fills the gap in the measurement of electrical conductivity of Ecoflex materials.The innovation of the Ecoflex film material conductivity measurement device lies in the contact separation TENG measurement function The advantages of Ecoflex film conductivity are that the displacement current based AC test has no strict requirements on the geometry of the sample,and no specific shape is required,easy to operate,and can be in-situ detection.In addition,we provide a plantar energy harvesting scheme that can be used for the conversion of mechanical energy to electrical energy.
