“…По сравнению со стеклянной посудой, емкости из полиэтилентерефталата (ПЭТФ) для хранения и транспортирования жидкостей имеют меньшие массу и хрупкость [1][2][3]. Одним из основных недостатков ПЭТФ емкостей является относительно большая естественная убыль жидкостей при длительном хранении [4][5][6]. Возможный способ снижения диффузионной проницаемости ПЭТФ заключается в физической и химико-физической модификации поверхности готового изделия [7][8][9].…”

The effectiveness of surface modification of polyethylene terephthalate with a mixture of fluorine and oxygen to reduce the permeability to water and aqueous ethanol solutions has been studied. We obtained a decrease in the permeability coefficient of the modified fi lm for water and ethanol solutions, the degree of decrease in the permeability coefficient depends on the chemical composition of the liquid. Oxyfluorination leads to the production of a modified fi lm with an increased liquid diffusion coefficient compared to the original fi lm, which is associated with the formation of local defects which is confirmed by micrographs made with of an atomic force microscope and by measuring the surface roughness of the original and modified films.
