The influence of thermal treatment and treatment by the liquid nitrogen of cocoons, on electric properties of the natural silk fibroin has been studied. It Is Installed that when treatment cocoon by liquid nitrogen is saved, correlation amorphous and crystalline parts of fibroin and concentration submicrocracks in them little changes, than when heated by air and UHF field. Growth of degree crystallinity polymer brings to some to increase their aggressive voltage.
