Preparation and Triboelectric Properties of Chitosan Conductive Gel
摘要
Abstract
Triboe nanogenerators(TENG)could effectively recover and utilize mechanical energy to generate electricity,which had great advantages in self-driven sensors.However,most triboelectric materials were petroleum-based,while the output performance of chitosan-based materials in biomass materials was low.Therefore,it was important to develop chitosan-based triboelectric materials with high output performance.In this study,phytate-chitosan/polyethylenimide(PA-CS/PEI)hydrogel was constructed using chitosan(CS),phytic acid(PA),and polyethylenei mine(PEI).This enabled the formation of a stable three-dimensional network structure with strong chemical cross-linking,and gold nanoparticles(AuNPs)was introduced to form a nanocomposite hydrogel system.When the mass fraction of chitosan in 25 mL chitosan-hydrochloric acid solution was 4%,the composite gel of PA-0.4%CS/PEI was prepared by adding 2 mL of 50%PA and 0.5 mL of 2%PEI,and its yield stress(1.6 MPa)was 4 times that of phytic acid chitosan gel(PA-2%CS,0.4 MPa).When the amount of AuNPs added in PA-CS/AuNPs/PEI hydrogel was 0.005 g,the conductivity of PA-0.4%CS/5AuNPs/PEI was 0.099 S/m,and the current value and power density were 11.1%and 23%higher than that of PA-CS/PEI,respectively,indicating that PA-CS/AuNPs/PEI had good electrical conductivity and triboelectric performance.This not only provided a new idea for energy harvesting,but also had a promising application prospect in flexible wearable sensors.关键词
