I want to prepare a cellulose-based biopolymer solid electrolyte by solution casting technique. However, choosing the right cellulose derivative has been my major challenge. Among the many factors to consider are amorphousness, mechanical stability, solubility in water etc of the cellulosic material. Is carboxy methylcellulose the right choice for me?
For your aim, it seems CMC is a good candidate. But please, note that there is another factor in the electrolyte property occurring - the degree of substitution in cellulose derivative. I would recommend you try also sulfated cellulose derivative. The main problem of this ester is stability in the water solution. But we have solved this problem by regulating its substitution pattern location along with cellulose AGU.

Thank you for your answer and suggestion (@ Nodirali S. Normakhamatov ). Is CMC soluble in water? I read that it is quite difficult to dissolve CMC in water. MC, on the other hand, dissolves quite easily in water.
The solubility of CMC also depends on its MW and DS. The sodium salt form of carboxymethyl cellulose is water-soluble from its DS
