摘要

Utilizing smart materials sourced from bio-resources is essential in the context of the circular economy and the increasing societal desire for digitization. This work outlines the development of resistive sensor applications utilizing composites of gelatin and copper nanowires (CuNWs), aiming to replace synthetic polymers with natural alternatives in multifunctional composites. The physical interactions between the copper nanowires and the hydroxyl groups in gelatin have been demonstrated, and the copper nanowires are uniformly dispersed throughout the gelatin matrix. The incorporation of CuNWs into the gelatin matrix enhances the thermal stability of the gelatin, however, the amount of CuNWs did not alter triple helix configuration of polymer matrix. Composites containing 6 wt% CuNWs have optimal electrical conductivity of 0.98554 S cm− 1, although these electrical, mechanical and antibacterial characteristics are influenced by the concentration of Cu NWs. The differences in the composite’s bending resistance and optimal pressure facilitate the advancement of eco-friendly antibacterial multifunctional sensing composites characteristics, potentially applicable in advanced touch sensing electrical gadgets.
