Metal-Free and Carbon-Free Flexible Self-Supporting Thin Film Electrodes

Conductive polymers are promising for application in the medical and sport sectors, e.g. thin wearable health monitoring systems. While many today’s electrodes contain either carbon or metals as electrically conductive filler materials, product design manufacturing has an increasing interest development of metal free free, purely polymer based electrode materials. conducting have generally rather low electrical conductivities compared to carbon, they offer broad options industrial processing, well dedicated adjustments final properties aspect, such colour, water repellence, mechanical flexibility addition their properties. The blends, on is thus timely high importance new attractive flexible electrodes. We developed material formulation processing techniques fabrication self-supporting film polyaniline (PANI) polyvinylidene fluoride (PVDF) blends. Electrical four-point probing was used evaluate conductivity different techniques. Optical microscopy atomic force measurements corroborate observed obtained even at PANI concentrations revealing nanoscale distribution within Our flexible, smooth, repellent were furthermore successfully tested under bending upon storage over a period several months. This opens perspectives medical, health, sports applications.
