- Аннотация: For the first time, a pronounced biocidal activity of modified polymers with a porphyrin content of 21.4 μM(0.002 wt%) against Staphylococcus aureus was demonstrated. In order to develop new biocidal polymer coatings,a study was carried out on diglycidyl ether of bisphenol A (DGEBA) and porphyrin-modified oligomeric diaminesystems. The study investigated the solubility of porphyrins in oligomers through experimental and theoreticalmeans, using Van Krevelen’s approach of additive group contributions. Fully cured epoxy-amine polymer materialsmodified with varied free-base tetraarylporphyrins were obtained. The materials were studied by means ofthermogravimetry, differential scanning calorimetry, UV–Vis and fluorescence spectroscopy. The proposedapproach to the formation of modified epoxy-amine materials allows preservation of the photophysical propertiesof porphyrins, including their photostability. The addition of modifiers in 4.28–21.4 μM range of concentrationsmakes it possible to keep the thermophysical and thermochemical properties of the polymer matrix.
