The main directions of creating new forms of anti-fouling coatings for hulls of sea vessels lie in the field of obtaining an optimal biocide or mixture of biocides. Copper (I) oxide and copper-containing compounds are currently used as the main biocide in such compositions. To obtain competitive biocides containing copper (I) oxide, it is necessary to use relatively cheap inert fillers. The authors proposed a method for producing pigments based on titanium (IV) phosphate and copper compounds that have toxic effect on marine microorganisms for use in coatings that prevent biofouling of ship hulls in seawater. It is shown that by varying the initial ratio of Cu (II) : Ti (III) in the composition of the pigment, the order of mixing, and the temperature of heat treatment of the pigment, it is possible to change the content of various copper compounds in the polymer matrix of titanium phosphate. The obtained samples were studied using the X-ray diffraction, differential scanning calorimetry, scanning electron microscopy methods and other. Thermal transformations of titanium (IV) phosphate samples containing copper in different oxidation states were studied by thermal synchronic analysis in air and nitrogen.
The conditions for obtaining a pigment with a maximum content of copper (I) oxide, necessary for prolonged inhibition of fouling, were found. The ability of the compositions to leach copper and phosphate ions in distilled water and in water similar in composition to seawater, depending on the conditions of heat treatment, was studied. Evaluation tests of the biocidal activity of the obtained pigments in relation to ciliates Tetrachimena piriformis and test cultures of bacteria Staphylococcus aureus, Bacillus subtilis were carried out.
