Preparation of a high-performance chitosan-based triboelectric nanogenerator by regulating the surface microstructure and dielectric constant

Abstract

The rapid development of electronic technology has put forward higher requirements to find a more suitable energy source. The development of triboelectric nanogenerators (TENGs) has revealed widespread success in converting...

Enhanced Energy Harvesting Performance of Triboelectric Nanogenerators via Dielectric Property Regulation

“…Thus, metal materials and some polymers are widely used as friction-positive materials because they are rich in free electrons and can provide electrons during friction. However, such materials are usually expensive or nondegradable. − Many biodegradable and renewable materials are promising candidates to be TENG’s friction materials for sustainable energy collection. , Chitosan is the product of N-deacetylation of chitin. It contains a large number of −OH and −NH 2 groups, and the −OH and −NH 2 groups can easily produce chemical reactions. , Thus, it can composite with other functional materials to enhance the output performance .…”

Enhanced Triboelectric Nanogenerator Based on a Hybrid Cellulose Aerogel for Energy Harvesting and Self-Powered Sensing

“…These nondegradable materials significantly compromised the overall sustainability of the TENGs. Therefore, it is vital to build a biobased TENG with excellent performance. , Cellulose with biocompatibility, biodegradability, and thermal stability is the most prevalent natural polymer on earth. Bacterial cellulose (BC) produced by Acetobacter xylinum under a particular environment has high crystallinity and excellent manufacturability.…”

Natural bioproducts’ hybridization creates transient dynamic electret nanogenerators

“…3–5,8–14 In particular, the transient energy harvesters are able to convert environmental physical energy into electricity using materials such as piezoelectrics, photovoltaics, and triboelectrics. 3–5,8–16 But so far, there have been a limited number of available transient energy materials, and obstacles continue to prevail in constructing transient energy harvesters with desired operational characteristics. 3–5,8–16…”
