FIELD: medicinal engineering. SUBSTANCE: invention relates to technology of preparing material based on Carbyne finding use in medicine as a material for manufacturing prostheses being in close contact with blood, for example, those for heart valve, blood vessels, etc. Method consists in treating fibers or film based on vinylidene fluoride-tetrafluoroethylene (1-6 wt %) copolymer with potassium hydroxide in mixture of ethanol with 20-90 wt % 1,4-dioxane in presence of excess solid potassium hydroxide. Dehydrofuoridizing solution of invention may be used for greater by an order of magnitude amount of polyvinylidenefluoride as compared to that in known method. EFFECT: intensified process. |
