The mechanism of the high frequency condensive complex plasma modification of polyurethane membrane coatings in air is investigated. The study revealed that after plasma modification in air, oxidation and hydrolysis of polyurethane membrane coatings occurs, which is expressed in an increase in the intensity of absorption bands corresponding to primary OH groups in the range of wave numbers 1005–1070 cm −1 , 1310 cm −1 and 1420 cm −1 , as well as in partial destruction of polyurethane chains with the formation of urea groups, which corresponds to the vibrations of CO-groups in the range of wave numbers 1590–1690 cm −1 .
