摘要: A novel conductive anionic hydrogel was synthesized for use as a solid electrolyte electrochemical impedance spectroscopy (EIS) characterization of the barrier properties protective coatings on outdoor metalworks, such bronze sculptures. The AMPS-co-PAA soaked in variety aqueous salt solutions and characterized by swelling capacity conductivity order to determine most appropriate gel/liquid combination culturally significant objects. K2PIPES-equilibrated hydrogels were selected preferred electrodes this particular application used measure coated substrate, yielding spectra similar those from standard liquid cells.
