NOVELTY - A polypyrrole/polyacrylic acid composite gel electrolyte is prepared by dissolving pyrrole monomer in organic solvent to prepare mixed solution, and adsorbing mixed solution by polyacrylic acid polymer to form gel; dissolving iodine simple substance in mixed organic solvent; soaking gel in iodine initiating agent solution, and reacting to obtain polypyrrole/polyacrylic acid complex; drying the acid complex, and removing solvent to obtain composite conductive high molecular substance; and soaking the composite conductive high molecular substance in liquid electrolyte.    USE - Method for preparation of polypyrrole/polyacrylic acid composite gel electrolyte (claimed) for dye-sensitized solar cell, lithium ion battery, super capacitor, and photochromic material.    ADVANTAGE - The method provides gel electrolyte having high conductance and high stability.    DETAILED DESCRIPTION - Preparation of polypyrrole/polyacrylic acid composite gel electrolyte, comprises:    (A) dissolving pyrrole monomer (10-90 vol.%) in organic solvent to prepare mixed solution, and adsorbing the obtained mixed solution by the polyacrylic acid polymer for greater than or equal to 24 hours to adsorb and balance the polyacrylic acid polymer to form gel;    (B) dissolving iodine simple substance in mixed organic solvent comprising N-methylpyrrolidone, ethanol, methanol, and acetonitrile liquid;    (C) soaking the gel reaching adsorption equilibrium in the iodine initiating agent solution which is 1-10 times the volume of the gel, and reacting at - 20-30 degrees C for 24 hours to obtain polypyrrole/polyacrylic acid complex;    (D) drying the polypyrrole/polyacrylic acid complex, and removing solvent to obtain composite conductive high molecular substance; and    (E) soaking the composite conductive high molecular substance in liquid electrolyte that is 1-20 times the volume of the substance, the electrolyte comprising organic iodate (0.10-0.65 mol/L), inorganic iodate (0.10-0.65 mol/L), iodine (0.01-0.50 mol/L), pyridine (0-0.65 mol/L), and organic mixed solvent, and adsorbing for 24 hours to reach liquid absorbing balance.
