Adsorption, Mobility and Organization of Organic Molecules at Clay Surfaces Probed by Photophysics and Photochemistry.
Abstract
The purpose is to study the polymerization of the detergent (methacryloyloxyethylmethyldiodecylammonium chloride) on a clay surface, and to study the properties of clay particles coated with the obtained polymer. Such ionic polymers are used in a variety of industrial products as thickners, dispersants, flocculants, ion exchange resins, etc... Their suitability for these applications can be referred to the great hydrophilicity and especially to the highly polar character which enable these substances to adsorb other polar compounds, such as dye-stuffs, charged colloidal particles and ions. Before proceeding with this polymerization however, the properties of the monomer adsorption have been studied first. As fluorescent probe, 3-(1-pyrenyl)propyltrimethylammonium bromide (P3N) has been used (1). Three different clays are used in our study: Barasym, a synthetic montmorrillonite, Hectorite and Laponite, a synthetic Hectorite.
