摘要
为提高微型纳米发电机的工作效率,采用分段浸渍的方法制备一种连续性分段式热电纱线;对热电纱线进一步编织,使其力学性能得到加强,同时具备摩擦电输出能力。对制备的热电纱线的最佳工艺条件、最佳浸渍次数和最佳编织截距进行探究,发现N型溶液中聚乙烯亚胺的最佳质量分数为6%,N型和P型纱线的最佳浸渍次数均为3次,智能纱线的最佳编织截距为1.0mm,在该条件下可以得到一种力学性能及输出电信号良好的热电-摩擦电智能纱线,且能够直接参与工业化织机的织造。研究结果为热电发电机与摩擦纳米发电机的结合提供了一种可行的方案。
To improve the working efficiency of micro-nano generators,a continuous segmented thermoelectric yarn was prepared using a segmented impregnation method.The thermoelectric yarn was further knitted to enhance its mechanical properties while imparting triboelectric output capability.The optimal process parameters,impregnation cycles,and knitting spacing for the prepared thermoelectric yarn were investigated.It is found that the optimal mass fraction of polyethyleneimine in the N-type solution is 6%,the optimal number of impregnation cycles for both N-type and P-type yarns is three,and the optimal knitting spacing for the smart yarn is 1.0 mm.Under these conditions,a thermoelectric-triboelectric smart yarn with excellent mechanical properties and electrical output signals can be obtained.Moreover,it can be directly integrated into industrial weaving machines.The research results provide a feasible approach for the combination of thermoelectric generators and triboelectric nanogenerators.
