Abstract
Proton-conducting non-porous nature of k-carrageenan-based flexible solid electrolytes was prepared by facile solution casting technique. Altering the composition of NH4COOH, free ion percentage (%) was improved significantly and contributed vital role on the proton conductivity to an utmost level of 8.54 × 10−4 Scm−1. Especially, increasing the composition of protonic carrier, electrochemical stability window was tuned tremendously and topmost value of 6.3 V was captured for the 0.4 (M wt%) NH4COOH added electrolyte. Also, interfacial adhesion energy of the electrolytes was enhanced to the maximum level of 96.27 Jm−2, inferred from contact angle measurements. The obtained significant electrochemical performance of k-carrageenan-based samples is an excellent substitute direction towards the cost-effective and eco-friendly wearable electrical applications.
