Rheological Screening of PVA Solutions for Thin Film-forming Processes

It is well-known that the rheological properties of polymeric materials in solutions undergo a liquidsolid,liquid-glass or liquid (sol)-gel transition and render great impacts on their processing and finaluse. Regarding its good thin film formation capability, understanding the rheological properties ofpolyvinyl alcohol (PVA) at different concentrations is essential for the design of materials withsuitable characteristics on macroscopic and microscopic scales. In the present study, the rheologicalproperties of PVA solutions with different concentrations (۲.۲, ۲, and %۸ w/v) were investigated toobtain desired solutions for film-forming processes.
