STUDY OF THE PROPERTIES OF ACRYLATE LATEXES DEPENDING ON THE CONTENT OF POLYPYRROLE PARTICLES

Original language description

The thesis deals with the study of polyacrylate latexes in which polypyrrole particles (PPy) were incorporated in the phase of latex polymer synthesis and the possibilities of their crosslinking, with a focus on latexes crosslinked at room temperature since it is necessary to improve or modify the mechanical, thermal and chemical properties of acrylate latex-based coatings. The mechanism of keto-hydrazide crosslinking was based on the reaction of a carbonyl group, which was part of the polymer latex particles, and diamine dissolved in the aqueous phase of the latex. Diacetonacrylamide was used as the monomer bearing the carbonyl functional group, and adipic acid dihydrazide was used as the diamine. Latexes were prepared by semi-continuous emulsion polymerization using a „one-pot“ synthesis strategy in which emulsion polymerization of acrylate monomers and oxidative polymerization of pyrrole were carried out in one reactor to prepare polyacrylate latexes containing 0, 0.2, 0.4 and 0.6 wt.% of incorporated PPy particles (based on the theoretical PPy content relative to the acrylate polymer). The latexes were characterized, and the efficiency of incorporation of polypyrrole particles into the colloidal system was determined. Furthermore, the effect of PPy particles on the physico-mechanical and chemical resistance of coating films was studied using a series of standardized tests. Last but not least, the influence of protective latex paint films on antimicrobial performance was studied.
