Аннотация: A linear polycation, poly(diallyldimethylammonium chloride), electrostatically interactswith anionic latex particles from a carboxylated butadiene–styrene copolymer in aqueous solutionthus forming an interpolyelectrolyte complex. A mutual neutralization of oppositely charged latexand polycation groups occurs at W = latex/polycation = 50 w/w ratio. At W = 27, an ultimatepolycation adsorption is reached, resulting in the formation of positive polycomplex particles, whileat W < 27, two-component systems are formed composed of positive polycomplex particles and freepolycation. A film created from the W = 12 formulation shows a high toxicity to Gram-positive andGram-negative bacteria and yeast. Repeated washing the film leads to partial removal of polycationand a 50% decrease in the activity of the film only towards Gram-negative Pseudomonas aeruginosa.The results indicate the potential for use of the mixed polymer formulations for the fabrication ofantimicrobial films and coatings.
