The energy crisis and the rise of flexible electronics call for a renewable and flexible energy source due to the inconvenience of the traditional power supply. A triboelectric nanogenerator (TENG) with high power density and flexibility can effectively harvest the mechanical energy in the environment and human body to form a self-powered unit. Carbon-based materials are widely used to fabricate a flexible and stretchable TENG. However, it is still needed to improve the output performance to meet the practical requirement. It is worth studying how to effectively introduce various dopants into carbon-based materials. Herein, we demonstrated a simple and effective method to enhance the performance of the flexible TENG based on AuCl3-doped crumpled graphene (CG). Instead of dangerous solvents, AuCl3 dissolved in deionized water was successfully introduced onto the surface of CG due to the crumple structure. Also, the performance can be greatly improved due to the dopants. The output voltage and current of the TENG based on doped CG with 1.2 mg/mL doping concentration can reach up to 80.6 V and 11.9 μA/cm2, respectively. Furthermore, the relationships between the output performance and environmental factors including working force, frequency, and temperature were investigated. This research introduces an easy fabrication and cost effective method to improve the performance of the TENG, which can be popularized to other material systems.

基于氯化金掺杂石墨烯的性能增强型柔性摩擦纳米发电机
由于传统电源的不便，能源危机和柔性电子的兴起要求可再生和柔性能源。具有高功率密度和灵活性的摩擦电纳米发电机（TENG）可以有效地收集环境和人体中的机械能，以形成自供电单元。碳基材料被广泛用于制造柔性和可拉伸的TENG。但是，仍然需要提高输出性能以满足实际需求。值得研究如何有效地将各种掺杂剂引入碳基材料。在本文中，我们展示了一种简单有效的方法来增强基于AuCl 3掺杂的皱纹石墨烯（CG）的柔性TENG的性能。AuCl 3代替危险溶剂由于其易碎结构，溶解在去离子水中的水已成功引入到CG表面。而且，由于掺杂剂，性能可以大大提高。基于掺杂浓度为1.2 mg / mL的CG的TENG的输出电压和电流分别可以达到80.6 V和11.9μA/ cm 2。此外，研究了输出性能与环境因素之间的关系，包括工作力，频率和温度。这项研究介绍了一种易于制造且具有成本效益的方法来提高TENG的性能，该方法可以推广到其他材料系统。
