I am working with PEO and gel polymers for electrolytes and I have been able to make a homogeneous casting but the gel that I make has a habit of sticking to itself if it rolls at all. During punching and subsequent use is coin cells if the gel rolls and touches itself during assembly it behaves much like two sticky sides of duct tape, making it impossible to get back apart and wasting the material.

Any one know of any additives or other techniques to make it easier during assembly that I could try that might make it less sticky? The control gel I am using is PEO+LiTFSI salt in solvent and cast then allowed to dry to evaporate the solvent.

PEO (Mw 1,000,000) in case that has anything to do with it.
