Abstract
The invention is in the field of methods for preparing polymer films, and of such polymer films. The method involves phase separation and requires only aqueous solution, eliminating the need for organic solvents. The aqueous phase separation involves contacting a polymer solution comprising a trigger-responsive polymer with an aqueous coagulation solution in which the trigger-responsive polymer is not soluble.
