Description
Summary:Various steps of the formation of nanocomposite coatings using organic-soluble film-forming agents are accompanied by changes in the structure of the aluminosilicate nanofiller under the action of various factors. Taking these factors into account is necessary for the development of coatings of preset structure with optimum properties. Swelling of various organoclays in pure and technical solvents and in a solution of an alkyd oligomeric film-forming agent was studied. The stability of organoclay dispersions in these media, the nanostructure of organoclay tactoids in dispersions, and the nanostructure of films of cured composites based on the alkyd oligomer were correlated. Factors favoring the swelling of organoclays in a film-forming agent solution and the formation of an intercalated nanocomposite were revealed. The effect of water vapor on the nanofiller structure in the composite film was characterized to evaluate the moisture resistance of the composite.
