RESEARCH AND SYNTHESIS OF CONDUCTIVE PPy/CNC POLYMER FOR FLEXIBLE ELECTRONICS APPLICATIONS

Abstract

A conductive polymer is a compound with the ability to conduct electricity and exhibit elasticity, with numerous applications in the research and fabrication of flexible sensors and soft robots. To synthesize a conductive polymer, it is necessary to combine conductive polymer materials with other suitable materials to provide durability and elasticity. In this study, we have combined conductive polymer polypyrrole (PPy), utilizing crystalline nanocellulose (CNC) as the substrate material, successfully creating a conductive and elastic composite material in the form of a hydrogel. Several experiments were conducted to verify the synthesis process and the material's conductive properties. The creation of CNC was confirmed by using the dynamic light scattering method and an electron microscope with the CNC’s particle diameter ranging from 50-650 nm. The electrical property of the hydrogel was verified in the form of a flexible strain sensor. The hydrogel material demonstrates the potential for applications in the fabrication of strain sensors, force sensors, flexible electronic applications, etc.
