A Ukrainian University offers a biocidal material based on polyurethane foam and iodine

A Ukrainian University since 2001 works on method of biocidal material based on polyurethane foam and iodine. It also develops methods of environmental, food, pharmaceutical and biomedical analysis. The proposed method of production of biocidal material is based on the modification of polyurethane foam with iodine. The intensity of sublimation of iodine from the surface of the sorbent, and therefore the degree of bactericidal nature of the material developed, is governed by the amount of pre-sorbed iodine under the special conditions. Tablets (diameter 10-15 mm, height 3-5 mm) and bandages (area - as needed, thickness (1-3 mm) of polyurethane foam, on which pre-sorbed milligrams of iodine are sorbed. Polyurethane foam is a soft, lightweight yet durable material that transmits air and moisture I2-PPU material is readily obtainable in laboratory and domestic conditions with PPU and crystalline iodine or iodine dissolved in alcohol or water (in KI3 form). Laboratory specimens of material based on polyurethane foam and iodine have been developed with varying degrees of sublimation of iodine from the surface of the carrier, and therefore with varying degrees of bactericidal activity. The proposed method of the polyurethane foam modification is simple and rapid. It can be fulfilled outside the lab. The material retains its bactericidal properties when stored in an airtight container indefinitely (at least three years) due to the establishment of an equilibrium between the gas and solid phases. The problems that it solves suggested method: - disinfection of drinking water of long storage; - dosed iodization of drinking water. The University is seeking companies which are interested in using the proposed biocidal material for the disinfection of the environment and food (water), as well as in the production of bactericidal dressings. Also of interest are companies that have experience in disinfection of drinking water and the production of antiseptics for medicine and household goals. The type of cooperation can include commercial agreement with technical assistance.
