T1 - Electrochemical study of polyaniline/silicon dioxide containing coatings in geothermal solution N2 - Polyaniline/Silicon Dioxide containing coatings were electrochemically investigated in a saline geothermal solution. With the increase of exposure time, impedance values of coated specimens decreased at low frequency, which could be caused by the decrease of pore resistance due to electrolyte or water uptake. Coating system needs further optimization work.
