Evaluation of Bactericidal Action of 2-vinylpiridine Copolymers Containing Quaternary Ammonium Groups and Their Charge Transfer Complexes

Abstract: Abstract:We report the development of copolymers based on 2-vinylpyridine with different porosity degrees. The copolymers were quaternized with methyl iodide and acrylonitrile to introduce quaternary ammonium groups on pyridine units. To prepare charge transfer complexes, the unmodified copolymers and their derivatives quaternized were impregnated with iodine. The antibacterial properties of all the polymers were evaluated ranging from of the Escherichia coli strain. The unmodified copolymers did not have anti… Show more

“…A capacidade desinfetante de iodo e de seus derivados é reportada por diferentes autores, assim como o uso de materiais catiônicos com propriedades bactericidas [10][11][12][13][32][33][34][35][36][37][38][39][40][41][42][43][44][63][64][65][66] . O iodo é conhecido como agente antimicrobiano, pois apresenta facilidade em penetrar na parede celular dos micro-organismos, inibindo a sua síntese vital.…”
