How to dissolve cellulose to get a transparent film? kindly suggest me a chemical to convert dissolved polymer into a gel or recommend a plasticizer?
Hey there P. Saravana Kumari! Let's dive into it. To dissolve cellulose and create a transparent film, you P. Saravana Kumari can use an ionic liquid like 1-ethyl-3-methylimidazolium acetate ([EMIM][OAc]). It's known for its ability to dissolve cellulose effectively, resulting in a clear solution.
Now, for turning the dissolved polymer into a gel, you P. Saravana Kumari might want to consider using a gelling agent like gelatin or agarose. These substances can form a gel when the solution cools down or undergoes a change in pH.
As for plasticizers, you P. Saravana Kumari could go for something like glycerol or polyethylene glycol (PEG). These are commonly used to increase the flexibility and durability of the cellulose film while maintaining its transparency.
Hope this helps! Let me know if you P. Saravana Kumari need more details or have any other questions.

Dissolution of cellulose in Schweizer’s reagent (ammoniacal Cu hydroxide solution) is one of the most well-known methods for dissolving cellulose. The resulting dark-blue highly viscous cellulose solutions can be drawn into verythin threads to form fibers and films after fixing the spinning solution with acids, bases, or salts. These films provide aneven coating on the cotton fiber.

Dear professors,
Thanks for the solution to long running problem. we forgot to set the pH of the dissolved solution. Hence found difficulty in forming a sheet. Now we will proceed ahead with your valuable guidance and support. Thank you professors
