“…4, 5). As opposed to γ sterilization, autoclaving does not promote the retention of the regions of destruction obtained during the treatment in Amount of pores plasma [6], which affects the roughness parameters of the membranes.…”

“…It was earlier shown in [6] that the action of plasma leads to significant changes in the structure and properties of TMs, in particular, the roughness increases, regions of destruction are formed, and hydrophilicity of the surface increases. In addition, the treatment of the material in plasma leads to a change in the chemical composition of the surface, increase in the number of polar carbonyl and carboxyl groups, and, as a consequence, growth in the surface energy due to the growth in its polar component.…”

“…In addition, the treatment of the material in plasma leads to a change in the chemical composition of the surface, increase in the number of polar carbonyl and carboxyl groups, and, as a consequence, growth in the surface energy due to the growth in its polar component. It is interesting to note the action of the subsequent γ radiation on the TMs modified in plasma: both the roughness of the surface and number of the regions of destruction decrease [6].…”

“…A track membrane (TM) made of polyethylene terephthalate (PET) proved its worth as a material for glaucoma surgery [1][2][3] and has a strong potential in the use as a keratoimplant [4,5]. However, owing to the limited wettability of the surface of the membrane [6], there is a need for developing methods for modifying its physicochemical properties. One of the promising and modern methods for the modification of the surface of polymers is the action of low-temperature plasma [7][8][9], which changes only the thin near-surface layer of the polymer without affecting its bulk characteristics owing to the small penetration depth of the active particles into the material [10][11][12][13].…”

The influence of modification by low-temperature atmospheric-pressure plasma and steam sterilization on the properties of track membranes based on polyethylene terephthalate is studied. It is found that the action of hot steam under pressure changes the topography of the surface of the membranes with the formation of artifacts in the form of large oval-shaped protrusions with a height of 300-400 nm and a density of up to 0.007 protrusions/μm 2 on the surface, increases the surface roughness by 40% and the wetting angle by 9°-18° for the initial membranes and by 36.8°-39.6° for the membranes modified in plasma, and decreases their surface energy to the initial value of 33 mJ/m 2 . Despite the morphological and structural changes in the surface, sterilization by hot steam under pressure does not lead to any noticeable change in the surface charge and ζ potential of the track membranes. Hot steam under pressure does not promote further crystallization of the membrane, keeping the polymer with a crystalline phase of 40-42%. Thus, to preserve the properties acquired by the membrane after the plasma treatment, it is necessary to search for a different sterilization method (gamma radiation, ethylene oxide sterilization).

“…There are various surface modification techniques such as corona treatment, UV, flame, gamma ray, ion beam, electron beam irradiations, laser treatments and glow discharge plasma treatment [7][8][9][10][11]. Among these techniques, glow discharge plasma treatment technique is considered to be the most promising method for the modification of the surface properties of polymeric materials.…”

In this paper, the polystyrene (PS) film surface was treated using DC glow discharge nitrogen (N 2) and argon (Ar) plasma to improve the wettability and antibacterial properties. The untreated and plasma treated surfaces were characterized by contact angle, FTIR, XRD and SEM analysis. The antibacterial activity of untreated and plasma treated PS films was evaluated using optical density (OD) technique against Staphylococcus aureus bacteria. The results of the PS film surface treated in both N 2 and Ar showed a noticeable increase in the wettability due to the increase in the roughness and the introduction of oxygen-containing polar groups as corroborated with SEM, weight loss calculations and FTIR spectra. The results of antibacterial activity showed that the treated samples inhibit the bacterial growth. The Ar treatment created more oxygen-containing polar groups and increase roughness on the PS film surface and extensively modified the polymer surface than the N 2 treatment.
