Abstract:
1. A method of producing a basic polyelectrolyte film of blended polyvinyl alcohol (PVA) and quaternary amine, comprising the following steps: obtaining a polar organic solvent, and separating it into two reaction vessels; adding a polyvinyl alcohol into said polar organic solvent contained in one of said two reaction vessels, and allowing said polyvinyl alcohol to completely dissolve in said polar organic solvent in order to form a PVA-containing reactant solution; adding a quaternary amine into said polar organic solvent contained in the other of said two reaction vessels, and allowing said quaternary amine to completely dissolve in said polar organic solvent in order to form a quaternary amine-containing reactant solution; mixing said PVA-containing reactant solution and said quaternary amine-containing reactant solution to initiate a polymeric blending reaction and form a solution of the product of said polymeric blending reaction; pouring said solution of the product of said polymeric blending reaction onto a tray, and allowing said polar organic solvent to vaporize completely in order to form a polymeric film; and stripping off said polymeric film from said tray, and soaking said polymeric film in an alkali-hydroxide solution to obtain said basic polymer electrolyte film of blended polyvinyl alcohol and quaternary amine.
