제목 DextrinDADMAC Hydrogel Electrolytes ForSodium Energy Storage Devices​
초록 .Biopolymers are inherently renewable, abundant in nature, nontoxic,biodegradable, and cheap. Dextrin is a widely used material with a variety ofapplications like food industry, textiles and medical products. Dextrin hasether group. Ether groups are present in each dextrin molecule likePoly(ethylene oxide) (PEO). The ether oxygen atoms on the PEO chains coordinatewith the Alkali ions like lithium ions, resulting in the dissociation of bothcations and anions. And dextrin’s ether group will expected to interact like PEO’sethergroup. I used a double network system to make dextrin electrolytes. Thehydrogels have been characterized by Linear Sweep Voltammetry (LSV), andElectrochemical Impedance Spectroscopy (EIS). Confirming physical structure bySEM. The Dextrin hydrogel is found to have an ionic conductivity of 23.9 × 10-3 S cm−1 at25 °C.​
