摘要
The energy crisis and environmental pollution have always been the main challenges facing the sustainable development of the world. The triboelectric nanogenerator is an efficient energy device with outstanding characteristics such as sustainability, high electrical output performance and unlimited material selection, and its unique self-driving system can ensure the continuous and reliable power supply for devices. Cellulose and its derivatives are a kind of renewable and easily degradable natural biological macromolecular materials with wide sources and environmental friendliness. Paper/cellulose-based triboelectric nanogenerator using natural cellulose-based materials as electrode material is a low-cost, abundant and renewable energy device. The use of the paper/cellulose-based triboelectric nanogenerator can alleviate the energy crisis and environmental pollution to a certain extent. Firstly, the four modes of the triboelectric nanogenerator and the effect of the electrode material on the triboelectric nanogenerator are described briefly. Then, the effects of the structural optimization and surface modification on the electrical output performance of paper/cellulose-based triboelectric nanogenerator are reviewed. And the application and research progress of paper/cellulose-based triboelectric nanogenerator in self-power sensor, wearable and medical fields in recent years are summerized. ? 2021, The Editorial Board of Materials China.
