Abstract

ABSTRACT Recently, the triboelectric nanogenerator (TENG) has been widely studied for the development of flexible and wearable electronics. Among the various methods for TENG modification, melting near-field direct writing is a new method to fabricate solid-liquid TENG. Here, the electrospun PCL was introduced with traditional polymers to fabricate the compound solid triboelectric layer, and water, dimethicone and GaIn were chosen as the liquid triboelectric layers. In this paper, the solid substrate effect, temperature gradient effect, and the liquid substrate effect were compared in terms of TENGs. A free-standing model of TENG is employed in this paper, and the charge generated by the PCL-PI composite solid triboelectrical solid layer is more than 10 times higher than the pristine one, showing the high charge generating ability to melt near-field direct written microfibers. Furthermore, detailed investigation will be discussed how we can get a high the out-circuit voltage and short-circuit current. GRAPHICAL ABSTRACT

固液接触TENG采用熔融近场直写PCL纳米纤维结构

近年来，摩擦电纳米发电机(TENG)在柔性和可穿戴电子产品的发展中得到了广泛的研究。在各种改性方法中，熔融近场直接刻写是制备固液型改性材料的一种新方法。本文将静电纺PCL与传统聚合物结合制备复合固体摩擦电层，并选择水、二甲基硅氧烷和GaIn作为液体摩擦电层。本文比较了固体衬底效应、温度梯度效应和液体衬底效应。本文采用独立的TENG模型，PCL-PI复合固体摩擦电固体层产生的电荷比原始固体层高10倍以上，显示出高电荷生成能力，可以熔化近场直写微纤维。此外，还将详细讨论如何获得高的输出电压和短路电流。图形抽象
