Fluorescence microscopy images of UV irradiated monomolecular films of styrene-functionalized surfactants have complex domains without the fluorescence probe. We present the results obtained with one of these surfactants, di-n-octadecylmethy(p-vinylbenzyl)ammonium chloride (DOVAC), which suggests that these domains are clusters of polymeric molecules. The sizes of the domains were measured by an image analysis system and correlated with the relative surface viscosity of the film. When photopolymerization is performed at constant surface pressure, the mean area of the domains varies according to irradiation time and the value of the surface pressure. The relative surface viscosity of the polymerized films depends on the size of the domains and increases abruptly when the size of the polymerized domains reaches about 50% of the total film area.

Abstract

Fluorescence microscopy images of UV irradiated monomolecular films of styrene-functionalized surfactants have complex domains without the fluorescence probe. We present the results obtained with one of these surfactants, di-n-octadecylmethy(p-vinylbenzyl)ammonium chloride (DOVAC), which suggests that these domains are clusters of polymeric molecules. The sizes of the domains were measured by an image analysis system and correlated with the relative surface viscosity of the film. When photopolymerization is performed at constant surface pressure, the mean area of the domains varies according to irradiation time and the value of the surface pressure. The relative surface viscosity of the polymerized films depends on the size of the domains and increases abruptly when the size of the polymerized domains reaches about 50% of the total film area.
