摘　　要：基于不同的可降解高分子材料作为摩擦层,铜片为电极层组装了系列摩擦纳米发电机(TENG),在相同摩擦层厚度及器件尺寸条件下,系统地研究了器件的输出性能,获得了这些可降解高分子材料的摩擦电极性排序,发现以海藻酸钠(SA)与聚丁二酸丁二醇酯(PBS)作为摩擦层的TENG表现出最佳输出性能,其最大输出电压达到46 V,电流0.7μA,转移电荷量4.68 n C.为进一步研究电极材料的影响,以SA与PBS作为摩擦层,石墨烯纸(GC-paper)作为电极构建了TENG器件,其输出电压达到88 V,电流1.25μA,转移电荷量14.6 n C.该TENG器件可以应用在能量收集与自供能传感等领域.本研究对环境友好型TENG器件的发展具有一定的参考价值.A series of triboelectric nanogenerators(TENG)devices were assembled using different degradable polymers as the friction layer and copper sheets as the electrode layer.Under the conditions of the same friction layer thickness and device size,the output performance of the devices was systematically investigated,and the friction electrode property ordering of these degradable polymer materials was obtained.It was found that the TENG with sodium alginate(SA)and polybutylene succinate(PBS)as the friction layer showed the best output performance,with the maximum output voltage reaching 46 V,current 0.7μA,and the transferred charge 4.68 nC.To further investigate the effect of electrode materials,a TENG device was constructed with SA and PBS as the friction layer and graphene paper(GC-paper)as the electrode,which achieved an output voltage of 88 V,a current of 1.25μA,and a transferred charge of 14.6 nC.TENG device can be applied in the fields of energy harvesting and self-supplied sensing.This study is of reference value for the development of environmentally friendly TENG devices.
