文摘

In this work, the water uptake of crosslinked urethane-based coatings in high humidity conditions as a function of crosslinking temperature was investigated. The water uptake values were measured using an electrochemical impedance spectroscopy technique by applying the Brasher–Kingsbury procedure. Water uptake values as high as 200% were observed in the current research. These anomalous results were explained based on capillary condensation of diffused water molecules in the nano-metrically (or nano-scale) rough hydrophilic surfaces of the pores formed by thermal degradation of the polyurethane network. The water uptake value is at its minimum when an effectively pore-free tight network formed at moderate crosslinking conditions.
