Madelat, Negin (author), Wouters, Benny (author), Visser, Peter (author), Jiryaeisharahi, Zahra (author), Marcoen, Kristof (author), Abrahami, S.T. (author), Hubin, Annick (author), Terryn, H.A. (author), Hauffman, Tom (author)In this work, the correlation between electrolyte transport properties and the variation of pigment volume concentration (PVC) in a series of organic coatings is explored. Using an odd random phase electrochemical impedance spectroscopy (ORP-EIS) approach, the diffusion of ions independent from water take-up is analysed. A higher PVC resulted...journal article 2024

Meeusen, M. (author), van Dam, J.P.B. (author), Madelat, N. (author), Jalilian, E. (author), Wouters, B. (author), Hauffman, T. (author), Van Assche, G. (author), Mol, J.M.C. (author), Hubin, A. (author), Terryn, H.A. (author)In this work, a new finite element modelling (FEM) approach is followed to model spatiotemporally resolved water uptake in organic coatings. To this aim, we start from a physical model, where not only Fickian diffusion of water is taken into account but also the adsorption/desorption reaction of water on the polymer matrix. Starting from a...journal article 2023
