“…PVC modication through the graing of acrylic acid represents an efficient route for materials properties enhancement, especially when considering membrane technologies or biomedical applications. [33][34][35][36][37] PVC -acrylic acid graing can be achieved by different routes such as plasma or electron beam facilitated graing of poly(acrylic acid), 14,27,33,35,38 photoinduced radical polymerization, 39 use of chemically induced physisorbed radical species, 36,40 in situ chlorinating gra copolymerization 41 and controlled polymerization reactions. However, in the case of controlled polymerization techniques for the fabrication of polyacrylic acid gras, the carboxyl functionality is usually obtained using a post-polymerization hydrolysis stage.…”

“…Noticeably, the infrared spectrum of the ETFE-2 membrane sample modified by AA/He plasma showed a significant change compared to that of ETFE-0, with the appearance of a distinct C=O stretching vibration peak at 1705 cm − 1 [ 11 , 15 ] and a broad peak in the range of 3700–2500 cm −1 containing OH stretching vibration peaks [ 17 , 18 ] and CH stretching vibration peaks [ 19 ]. These results indicate the appearance of some polyacrylic acid (PAA) on the surface of ETFE membranes after He/AA plasma treatment.…”

Fluorine resin membranes with excellent chemical resistance have great potential for the application of high-performance chemical protective clothing. However, it is difficult to integrate fluorine resins into other materials such as fabrics due to their lower surface energy and poor bondability, making the fabrication of composite fabrics and the further seal splicing challenging. In this study, atmospheric pressure dielectric barrier discharge (DBD) plasma in helium (He) and helium/acrylic acid (He/AA) mixture atmospheres were used to modify two kinds of fluorine resins, ethylene tetrafluoroethylene (ETFE) and polytetrafluoroethylene (PTFE) membrane. The surface chemical properties, physical morphology, hydrophilicity and adhesion strength of the fluororesin membranes before and after plasma treatments were systematically analyzed. The results showed that the plasma treatment can modify the membrane surface at the nanoscale level without damaging the main body of the membrane. The hydrophilicity of the plasma-treated membrane was improved with the water contact angle decreasing from 95.83° to 49.9° for the ETFE membrane and from 109.9° to 67.8° for the PTFE membrane, respectively. The He plasma creates active sites on the membrane surface as well as etching the membrane surface, increasing the surface roughness. The He/AA plasma treatment introduces two types of polyacrylic acid (PAA)—deposited polyacrylic acid (d-PAA) and grafted polyacrylic acid (g-PAA)—on the membrane surface. Even after ultrasonic washing with acetone, g-PAA still existed stably and, as a result, improved the polarity and adhesion strength of fluororesin membranes. This work provides useful insights into the modification mechanism of DBD plasma on fluorine resins, with implications for developing effective strategies of integrating fluorine resin membrane to chemical protective clothing fabrics.

“…Also the hydrophilic properties of paper are enhanced by the argon plasma treatments, plasma power and treatment time. Ar plasma normally does not etch as strongly as oxygen plasma but its irradiation and plasma particle may react with oxygen, when the sample is exposed to the ambient air and may occur the aromatic rings and hydrophilic groups on surface (Fahmy and Friedrich, 2013; Fahmy et al , 2019; Ražić et al , 2020).…”

Purpose The surface energy of the printing material can be increased to desired levels with different chemicals or methods. However, the important thing is that the surface properties of printing material are not affected negatively. In this way the aim of this paper provide that the surface properties of matte and glossy coated paper is improved by the argon containing atmospheric pressure plasma device because the plasma treatment method does not occur surface damaging on the papers. Design/methodology/approach In experimental studies, test samples cut from 160 mm × 30 mm in size from 115 g/m2 gloss- and matt-coated papers were used. The plasma treatments of paper samples were carried out with an argon containing atmospheric pressure plasma device of laboratory scale that produces plasma of the corona discharge type at radio frequency. The optimized plasma parameters were at a frequency of 20 kHz and plasma power 200 W. A copper electrode of length 12 cm and diameter 2.5 mm was placed in the centre of the nozzle. Findings Research findings showed that the surface energies of the papers increased with the increase in plasma application time. While the contact angle of the untreated glossy paper is 82.2, 8 second plasma applied G3 sample showed 54 contact angle value. Similarly, the contact angle of the base paper of matt coated is 91.1, while M3 is reduced to 60.4 contact angles by the increasing plasma time. Originality/value Plasma treatment has shown that no chemical coating is needed to increase the wettability of the paper surface by reducing the contact angle between the paper and the water droplet. In addition, the surface energies of all papers treated by argon gas containing atmospheric pressure plasma, increased. Plasma treatment provides to improve both the wettability of the paper and the adhesion property required for the ink, with an environmentally friendly approach.
