“…The chemical changes in the near-surface area of the samples were observed by attenuated total reflectance Fourier transform infrared spectra (ATR-FTIR) for the mid-IR range of 4000–400 cm −1 , and the collected data are shown in Figure 4. The major peaks of PET were observed at the wavenumbers of: 720 cm −1 related to CH 2 rocking vibrations; 795 cm −1 in the plane vibration of C–H; 850 cm −1 and 872 cm -1 corresponding to wagging vibration of O–CH 2 and out-of-plane C–H vibration, respectively; 975 cm −1 due to stretching of O–CH 2 ; 1015 cm −1 related to in-plane C–H vibration; 1095 cm −1 and 1243 cm −1 corresponding to asymmetric stretching vibration of C–O; 1340 cm −1 referring to CH 2 wagging; 1410 cm −1 related to C–H bending vibration; 1471cm −1 related to CH 2 bending; 1511 cm −1 referring to C–H bending vibration; 1718 cm −1 due to C=O stretching band [48,49,50]. The absorption peaks observed between 2850 and 3000 cm −1 were attributed to aliphatic C–H stretching vibrations [47,50].…”

Anticoagulant Polyethylene Terephthalate Surface by Plasma-Mediated Fucoidan Immobilization

Biomaterial-based blood clot formation is one of the biggest drawbacks of blood-contacting devices. To avoid blood clot formation, their surface must be tailored to increase hemocompatibility. Most synthetic polymeric biomaterials are inert and lack bonding sites for chemical agents to bond or tailor to the surface. In this study, polyethylene terephthalate was subjected to direct current air plasma treatment to enhance its surface energy and to bring oxidative functional binding sites. Marine-sourced anticoagulant sulphated polysaccharide fucoidan from Fucus vesiculosus was then immobilized onto the treated polyethylene terephthalate (PET) surface at different pH values to optimize chemical bonding behavior and therefore anticoagulant performance. Surface properties of samples were monitored using the water contact angle; chemical analyses were performed by FTIR and X-ray photoelectron spectroscopy (XPS) and their anticoagulant activity was tested by means of prothrombin time, activated partial thromboplastin time and thrombin time. On each of the fucoidan-immobilized surfaces, anticoagulation activity was performed by extending the thrombin time threshold and their pH 5 counterpart performed the best result compared to others.

“…The graft copolymerization involves the activation of the surface in the plasma of inert gas, as a result of which free radicals are created. They can be used as graft copolymerization centers by contacting (without plasma) the surface prepared in this way with an appropriate monomer, e.g., allylamine [ 21 , 22 , 23 ]. The antimicrobial agent molecules can then be anchored in the polymer “brush” thus produced, by intermolecular forces, for example, dipole–dipole interactions [ 22 , 23 ].…”

Anti-Mold Protection of Textile Surfaces with Cold Plasma Produced Biocidal Nanocoatings

The permanent anti-mold protection of textile surfaces, particularly those utilized in the manufacture of outdoor sporting goods, is still an issue that requires cutting-edge solutions. This study attempts to obtain antifungal nanocoatings on four selected fabrics used in the production of high-mountain clothing and sleeping bags, and on PET foil as a model substrate, employing the cold plasma technique for this purpose. Three plasma treatment procedures were used to obtain such nanocoatings: plasma-activated graft copolymerization of a biocidal precursor, deposition of a thin-film matrix by plasma-activated graft copolymerization and anchoring biocidal molecules therein, and plasma polymerization of a biocidal precursor. The precursors used represented three important groups of antifungal agents: phenols, amines, and anchored compounds. SEM microscopy and FTIR-ATR spectrometry were used to characterize the produced nanocoatings. For testing antifungal properties, four species of common mold fungi were selected: A. niger, A. fumigatus, A. tenuissima, and P. chrysogenum. It was found that the relatively best nanocoating, both in terms of plasma process performance, durability, and anti-mold activity, is plasma polymerized 2-allylphenol. The obtained results confirm our belief that cold plasma technology is a great tool for modifying the surface of textiles to provide them with antifungal properties.

“…Afterward, they coupled these particles with cyclodextrin for controlled release of menthol with the purpose of the treatment of cutaneous diseases [31]. In another study, Mrácek and coworkers firstly treated the polyester fabric surface with plasma, then grafted it with allylamine to obtain a wound healing biomedical material [32]. Joseph and Rajeev coated woven PET fabric with polyvinylidene fluoride and evaluated it in possible usage as sewing ring of prosthetic heart valves.…”

Propolis has biological activity due to its wide variety of phenolic compound content. Propolis usage in many areas such as cosmetics, food, medicine, and biomedicals is becoming widespread day by day due to its antibacterial, antifungal, antiviral properties. In this study, phenolics extracted from propolis were covalently bonded and immobilized on the surface of polyethylene terephthalate (PET) fabric with the aim of developing a technical textile for biomedical applications. To do so, PET fabric was aminated, and then the phenolics were immobilized using polyethylene glycol diglycidyl ether (PEGDGE) as the crosslinking agent. Formation of amine groups in PET structure and immobilization of the phenolics were proved by ATR-FTIR spectrums. Water contact angle of PET being 121° decreased to 110° and 97° after the amination and the immobilization, respectively. Optical microscope images were taken to monitor morphological changes after the processes. DSC results revealed a new endothermic peak at around 40 °C for modified PET. Tensile tests showed that tensile strength of the fabric weakens upon modification, while a healing effect occurs during immobilization. Antibacterial tests revealed that propolis extract immobilized fabric has an antibacterial activity against gram negative (E. coli) bacteria.
