Title: | Environment-resisted flexible high performance triboelectric nanogenerators based on ultrafast self-healing non-drying conductive organohydrogel | Authors: | Huang, LB Dai, X Sun, Z Wong, MC Pang, SY Han, J Zheng, Q Zhao, CH Kong, J Hao, J |
Issue Date: | Apr-2021 | Source: | Nano energy, Apr. 2021, v. 82, 105724 | Abstract: | Triboelectric nanogenerator (TENG), a promising energy harvesting technique, has attracted intense research interests in recent years for its applicability in portable and wearable electronics. Self-powered sensors with high sensitivity based on TENG have been widely reported. However, for practical applications, the survivability of TENG in harsh working environments is a vital issue which must be addressed. Herein, we report a hydrophobic, icephobic, and ultrafast self-healing TENG with outstanding non-drying and non-freezing properties for energy harvesting and self-powered sensor. Due to the excellent environment resistance and conductive capability of organohydrogel, the TENG shows much better electrical output stability in a wide temperature range than conventional hydrogel-based TENG which suffers from being frozen at low temperature and dried at high temperature. Moreover, the ultrafast self-healing function enables the electrical output performance of the TENG rapidly restore without delay. The TENG in this work demonstrates an open-circuit voltage of 157 V, a short-circuit current of 16 µA, and a short-circuit charge of 29 nC. The maximum output power density reaches up to 710 mW m−2. This research might pave a new road for novel applications of TENG in harsh environments with reliable output performance and self-healing capability for practical applications. | Keywords: | Environment-resisted Non-drying Organohydrogel Self-healing Triboelectric nanogenerators |
