Abstract

Studies on the physicochemical properties and applications of polymer coatings obtained from the dispersion of aqueous polyurethane cationomers modified with silsequioxanes functionalized with OH groups [(PHIPOSS) (Table 1)] have been presented. The obtained cationomers has been classified as possessing a nanocomposite structure and high, increasing with PHIPOSS content, thermostability (Fig. 1, Table 3). The coatings were studied with special emphasis on determining the influence of PHIPOSS on the interactions occurring in the rigid polyurethane-urea segments, on which the morphology of the obtained surfaces depend. The morphology was evaluated by microscopic analysis methods (Fig. 3,4, Table 5) and DSC (Fig. 2, Table 4). The surface energy (Table 2,6) and applicability of the coatings were also determined (Table 7). Preliminary studies indicate potential for application of the products obtained in the form of presented aqueous dispersions as environmentally friendly coatings on surfaces of hydrophilic character.
