Tetra-tert-butylphthalocyanine and Its Copper Complex in Surface Modification of Nonwoven Polymer Materials

Immobilization of tetra- tert -butylphthalocyanine and its copper complex on a chemically activated surface of nonwoven polypropylene and Dacron materials was studied with the aim of creating new materials with antimicrobial properties. A method of the chemical activation of the surface of the studied materials by aminolysis was developed. It was shown that chemical activation leads to a change in the roughness of the polymer surface and formation of nitrogen-containing surface functional groups, which increases the sorption capacity of the studied materials. The modified non-woven materials exhibit a sustained antimicrobial activity.
