FIELD: polymer materials.
SUBSTANCE: invention relates to the field of polymer materials, specifically to biodegradable polymer composite materials with antibacterial properties and can be used to impart bactericidal properties to surfaces, for the manufacture of bactericidal packaging materials and medical items with antibacterial properties. A bactericidal polymer composite material based on polylactide, including as an antibacterial agent a derivative of tetraphenylporphyrin, which is 5,10,15,20-tetrakis (4-n-hexyloxyphenyl) porphyrin, is proposed. The material can be made in form of a bactericidal film or in form of a bactericidal non-woven fiber material.
EFFECT: similar or higher antibacterial activity with a lower quantitative content of the antibacterial agent, high elasticity and a lower degree of crystallinity.
