In this work, Mg2+ modified chitosan (Mg2+/CS) is proposed and successfully designed. By investigating the effects of CS interaction on hydrogen bonding, dipoles, charge density, surface potential, roughness, coordination between verified mechanism improving tribological properties elucidated. The Mg2+/CS structure enhances intermolecular interactions, promoting formation new bonds increasing dipoles. Compared to CS, relative dielectric constant increased by 76%, potential 70 mV, root mean square roughness 39.4 nm. open-circuit voltage, short-circuit current, density triboelectric nanogenerator (TENG) fabricated from were 100%, 94%, 75%, respectively, compared CS-TENG pure CS. Mg2+/CS-TENG, significantly enhancing its transfer capability. Mg2+/CS-TENG provided power for photodetectors LEDs. exhibited excellent flexibility skin adhesion, converted mechanical energy generated human joint motion into electrical signals. with performance providing light research chitosan-based TENGs.
