Fig. 11: High-resolution field emission scanning electron microscopy (HR-FESEM) images and energy dispersive X-ray spectroscopy (EDX) mappings of protrusion patterns observed in SET1-ZnMM-RH%.
From: Early degradation mechanisms at the interface between acrylic grounds and oil paint films
a close-up of the protrusion with lipid medium separation visible on the paint layer surface; b elemental mapping of all detected elements in a specific area of the examined cross-section; c distribution mapping of calcium ions across the selected area; d distribution mapping of zinc ions across the selected area; e distribution mapping of sodium ions across the selected area; f distribution mapping of titanium ions across the selected area; g color legend of elements in maps; h elemental spectrum acquired at the protrusion site with lipid medium separation; i elemental spectrum acquired from the paint layer region. SET1 (commercial primed cotton canvas + oil paint film.). Zn zinc paint layer, MM brand Maimeri, RH% subjected to artificial ageing with % relative humidity variations.
