Preparation of agarose-based biopolymer electrolytes containing Calcium Thiocyanate: Electrical and electrochemical properties

CaSCN-agarose biopolymer electrolytes were prepared by infusing various amounts of CaSCN salts (0-40 wt.%) in 0.5 g of agarose. CaSCN-agarose biopolymer electrolytes had been prepared through a solution casting technique and had been kept in the oven for 36 h at the temperature range of similar to 8...
