“…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.

Surface modification of polylactide films was performed using a dielectric barrier discharge (DBD) with the aim of increasing proliferative activity of human fibroblasts on these films. It has been shown that during the plasma treatment of the polylactide film, nonlinear processes occur depending on the processing time. The effect of the dielectric barrier discharge on the modification of polylactide films was evaluated using IR spectroscopy, AFM, XPS, TSDC, and the wetting angle of the surface. The optimal processing time in DBD of polylactide films is 3 min for this installation, the proliferative activity increases by 10% compared to the original film. This treatment time provides an increased concentration of oxygen‐containing groups, optimal relief, and free surface energy of 55 mJ/m2 on the surface.Highlights The biocompatibility of the polylactide film was improved by 10% used DBD. The optimal processing time of PLA films in DBD is 3 min. The functionalization of the polylactide surface occurs non‐linearly.
