摩擦电纳米发电机（TENG）是一种简单且经济有效的装置，它将环境机械能转化为基于薄膜表面接触通电的电能。有限的表面电荷密度可能会影响TENG的整体性能。本文提出了一种基于电晕充电的新型驻极体薄膜的TENG (E-TENG)，与接触充电的薄膜相比，该薄膜的有效表面电荷密度大大提高。在不同的电晕充电电压、精确的充电距离和充电次数下，研究了E-TENG的短路电流、转移电荷密度和开路电压，以探索最佳的实验条件。发现E-TENG的短路电流、转移电荷密度和开路电压约为普通聚四氟乙烯（PTFE）薄膜基TENG的7倍。在电晕充电的基础上，制备了多层e - teng，研究了不同层数e - teng的短路电流、转移电荷密度和开路电压，以获得最佳性能。这项工作为提高有效表面电荷密度从而提高TENG的输出能力提供了一种有效的方法，这将极大地促进TENG在自供电便携式电子和传感器网络中的应用。
A triboelectric nanogenerator (TENG) is a simple and cost effective device that converts ambient mechanical energy into electricity based on the surface contact electrification of thin films. The limited surface charge density may affect the overall performance of the TENG. In this paper, a novel electret film based TENG (E-TENG) fabricated by corona charging is proposed that greatly enhances the effective surface charge density of the thin films as compared to those subjected to contact electrification. The short-circuit current, transferred electric charge density, and open-circuit voltage of the E-TENG have been investigated, using different corona charging voltages, pinpoint distances and times in order to explore the optimum experimental conditions. The short-circuit current, transferred electric charge density, and open-circuit voltage of the E-TENG are found to be about seven times larger than those of the ordinary polytetrafluoroethylene (PTFE) film based TENG. Based on corona charging, several multilayered E-TENGs have been fabricated, and the short-circuit current, transferred electric charge density, and open-circuit voltage of the E-TENGs with different number of layers are studied for achieving optimal performances. This work offers an effective approach for improving the effective surface charge density and thereby increasing the output capability of the TENG, which would greatly promote TENG applications in self-powered portable electronics and sensor networks.
