Gelling point

Simple coacervation involves the use of either a second more-water soluble polymer or an aqueous non-solvent for the gelatin. This produces the partial dehydration/desolvation of the gelatin molecules at a temperature above the gelling point. This results in the separation of a liquid gelatin-rich phase in assocation with an equilibrium liquid (gelatin-poor) which under optimum separation conditions can be almost completely devoid of gelatin. 

Dissolution the creation of an aqueous solution containing two different polymers, generally a protein and a polysaccharide, usually at a temperature above the gelling point and pH that is above the isoelectric point of protein.

G.R. Mitchell The first thing is that there are very, very strong solvent dependent configurations that can be generated, which people have studied in gels. Obviously, when you dry out the films you get quite close to a gelling point. Have you done any scattering smdies on the films ...
