Abstract
The present disclosure generally relates chitosan-based biopolymers and chitosan biopolymer film based triboelectric nanogenerators generating voltage and current using the triboelectric effect. The chitosan-based biopolymer is a reaction product of at least a chitosan and an acid, and optionally one or more component selected from starch, lignin and/or glycerol.
Claims13
A triboelectric nanogenerator comprising a chitosan-based biopolymer, wherein the chitosan-based biopolymer comprises a reaction product of a mixture comprising at least a chitosan and an acid, and at least one additional component comprising glycerol, starch, lignin or any combination thereof, wherein the chitosan-based biopolymer is presented as a film, wherein the film has a 30-90 wt % of chitosan, and wherein the triboelectric nanogenerator has a tunable output power density of 150-250 nW/cm2.
A chitosan based biopolymer, wherein the biopolymer is a reaction product of a mixture comprising at least a chitosan and an acid, and at least one or more component selected from the group consisting of starch, glycerol, lignin, and any combination thereof, wherein the chitosan based biopolymer is presented as a film, wherein the film has a 30-90 wt % of chitosan, wherein the chitosan based film is capable of generating a tunable output power density of 150-250 nW/cm2 in a triboelectric nanogenerator.
A method of preparing a chitosan based biopolymer, wherein the method comprises reacting a chitosan with an acid, and at least with a starch, glycerol, or any combination thereof to form a chitosan based gel;
- preparing a chitosan based film with the chitosan based gel;
- and treating the surface of the chitosan based film with a laser beam, wherein the chitosan based film is capable of generating a tunable output power density of 150-250 nW/cm2 in a triboelectric nanogenerator.
