Wearable electronics – electronic devices in clothes- allows for online measuring, monitoring and influencing people’s health and comfort. Wearable applications put new demands on the softness, conformability and electrical performance of materials, which demands a set of material properties that are met well by conjugated polymers (CP’s). Due to their poor mechanical properties, CP’s are most often used as electroactive coatings on biopolymers such as cellulose or silk, forming a composite. Till so far, CP designs have been unable to unify green processability, mechanical robustness and separation from the biopolymer scaffold at end-of-life. This lack of recyclability, and the fact that many garments are quickly discarded after purchase, adds problems to the already environmentally important textile industry [1]. Aiming to produce a greener electroactive CP coating for cellulose, we designed and synthesized a functionalized polar polythiophene with reversible crosslinking capability– PCAT. This polymer was designed with tuneable electrical conductivity and solubility. By using acid-base chemistry the solubility of PCAT can be switched from water soluble to insoluble, making it a potential recyclable electroactive coating for wearable electronics. As compared to previously reported [2], we have developed a greener synthetic route for PCAT, reducing the number of synthetic steps and use of hazardous chemicals. PCAT can be applied as a coating to commercial Lyocell threads from water and reversibly fixated with citric acid in its semiconductor form. In our efforts to obtain electrically conducting PCAT coatings through oxygen-mediated acid-doping, we observed that PCAT irreversibly crosslinked and lost the possibility for recycling. We established that hydrogen peroxide (H2O2) is produced upon doping of PCAT. To prevent formation of H2O2, we took inspiration from the “elephant toothpaste” experiment. We found that an addition of potassium iodide to the doping protocol prevents formation of H2O2 and restores the recoverability of PCAT from the cellulose
