Đánh giá sự thấm nước của một số màng sơn lót thương mại bằng phương pháp tổng điện trở điện hóa

Electrochemical impedance spectroscopy (EIS) has been applied to study the water uptake for four primer paint films J1 - J4 on carbon steel surfaces exposed to seawater. Based on the Brasher-Kingsbury equation, the water uptake was estimated from CC values calculated by both EIS data treatments: one from the high frequency Nyquist semicircle and the other by using Fit and Simulation software.
