Résumé : |
Defects in transparent, solvent-free vinyl ether, and allyl ether maleate-functional coatings have been studied using conventional optical microscopy, scanning electron microscopy, atomic force microscopy, scanning acoustic microscopy, and confocal laser microscopy. Vinyl ether films with different curing rates and allyl ether films with different crosslink densities were prepared, and the number and appearance of defects present in the films were compared. The varying curing rates were achieved by using different initiators, whereas the changes in crosslink density were obtained by using monomers with different functionalities. Defects, such as craters and surface crumpling, were observed. Higher curing rates and increased crosslink densities were both found to promote the formation of defects. Atomic force microscopy, scanning acoustic microscopy, and confocal laser microscopy proved to be useful techniques in the characterization of organic coatings, with the latter being particularly well suited for viewing the interior of transparent coatings. |
