Abstract

Model paint materials were generated by adding a range of inorganic materials into an epoxy. The inorganic materials included inhibitors (Zn ₃(PO ₄) ₂ and SrCrO ₄) and a filler (rutile TiO ₂).The SrCrO ₄ system was characterized using SEM, TEM, PALS and Raman spectroscopy and found to have an even distribution of inhibitor in the polymer matrix. X-ray tomography was performed on the mixed SrCrO ₄/TiO ₂ and Zn ₃(PO ₄) ₂/TiO ₂ systems. A new technique called data constrained modelling was combined with the tomographic technique to produce a 3D distribution of the inorganic phases within the polymer matrix.
