This study introduces a highly efficient and comprehensive strategy to engineer high-performance TENG(triboelectric nanogenerator) based on multifunctional polysuccinimide (PSI). With the ability of PSI to undergo facile nucleophilic addition with amines, sodium sulfate and quaternary ammonium chlorides having opposite charged groups are conjugated to PSI in varying densities. The resulting Sulfo-PSI and TMAC-PSI, respectively, processed into nanofibrous films, demonstrate highly enhanced and variable triboelectric properties based on the charge type and density. To further enhance the mechanical toughness and biocompatibility necessary for wearable applications, these PSI nanofibers are processed into alginate aerogel. The sustained triboelectric performance of this nanofiber-AG TENG as a wearable energy harvester and biosensor is examined and validated in detail. |
