| Résumé : |
A study on the development of an effective composition of polymeric antifouling coating based on acrylic copolymer with microencapsulated extract of natural origin and superdispersed polytetrafluoroethylene was carried out. A Raman spectroscopy study of the bacterial extract composition showed that the main component was a polyene pigment with 5 conjugated bonds. Encapsulation of ethyl acetate extract of Pseudoalteromonas piscicida 2202 was carried out, two types of microcapsules containing the microbial extract were obtained, and their morphology and efficiency of antifouling action in the coating were studied. Comprehensive studies of antifouling, anticorrosion, and mechanical properties of the coatings allowed identification of the most effective composition providing long-term protection in combination with satisfactory mechanical properties. It is shown that the use of silica nanocapsules with microbial extract in the coating is more effective for enhanced antifouling and mechanical performance. |
