“…In comparison with the measurement results found in the literature search, it can be said that in our work we managed to almost triple the strength in a shorter plasma treatment time [ 33 ]. This result is unique and testing on HIPS for plasma jet surface treatment has not been analysed.…”

The development of bonding technology and coating technologies require the use of modern materials and topologies for the demanding effect and modification of their wetting properties. For the industry, a process modification process that can be integrated into a process is the atmospheric pressure of air operation plasma surface treatment. This can be classified and evaluated based on the wettability, which has a significant impact on the adhesive force. The aim is to improve the wetting properties and to find the relationship between plasma treatment parameters, wetting, and adhesion. High Impact PolyStyrene (HIPS) was used as an experimental material, and then the plasma treatment can be treated with various adjustable parameters. The effect of plasma parameters on surface roughness, wetting contact angle, and using Fowkes theory of the surface energy have been investigated. Seven different plasma jet treatment distances were tested, combined with 5 scan speeds. Samples with the best plasma parameters were prepared from 25 mm × 25 mm overlapping adhesive joints using acrylic/cyanoacrylate. The possibility of creating a completely hydrophilic surface was achieved, where the untreated wetting edge angle decreased from 88.2° to 0° for distilled water and from 62.7° to 0° in the case of ethylene glycol. The bonding strength of High Impact PolyStyrene was increased by plasma treatment by 297%.

“…Figure 2a,b show the photographs of the prepared inks and printed patterns on the fabric substrate. Other than the optimization of the printing ink, the print quality depends on the surface of the substrate 35 . Figure 2c shows the ink contact angle with the fabric substrate, which is ~ zero due to the high absorption rate of the raw bamboo fabrics.…”

Electronic textiles have garnered significant attention as smart technology for next-generation wearable electronic devices. The existing power sources lack compatibility with wearable devices due to their limited flexibility, high cost, and environment unfriendliness. In this work, we demonstrate bamboo fabric as a sustainable substrate for developing supercapacitor devices which can easily integrate to wearable electronics. The work demonstrates a replicable printing process wherein different metal oxide inks are directly printed over bamboo fabric substrates. The MnO 2-nico 2 o 4 is used as a positive electrode, rGO as a negative electrode, and LiCl/PVA gel as a solid-state electrolyte over the bamboo fabrics for the development of battery-supercapacitor hybrid device. The textile-based MnO 2-nico 2 o 4 //rGO asymmetric supercapacitor displays excellent electrochemical performance with an overall high areal capacitance of 2.12 F/cm 2 (1,766 F/g) at a current density of 2 mA/cm 2 , the excellent energy density of 37.8 mW/cm 3 , a maximum power density of 2,678.4 mW/ cm 3 and good cycle life. Notably, the supercapacitor maintains its electrochemical performance under different mechanical deformation conditions, demonstrating its excellent flexibility and high mechanical strength. The proposed strategy is beneficial for the development of sustainable electronic textiles for wearable electronic applications. Smart electronic textiles have recently gained a lot of attention as a viable solution for the upcoming wearable electronics era 1,2. The electronic textiles/ garments have demonstrated enormous potential in various applications such as; healthcare monitoring devices, environmental monitoring devices, military applications, entertainment, fashion technology etc 2-4. Recently, the development of different textile-based electronic devices (like; wearable displays, wearable sensors, memory devices, and wearable transistors) have received greater attention from the scientific and engineering community, and their development is carried out on a rapid pace 4-6. However, one of the major challenges for commercialization and further growth of wearable electronics is the lack of a compatible power supply that may possess the same level of flexibility, durability, weight, biocompatibility, and strength as the device itself 7,8. The conventional energy storage devices fail to address these needs due to their rigid and bulky nature and also their inability to mount/perform on moving surfaces as is a critical need of wearable devices mounted on human and other beings 1,9-11. Therefore, there exists a strong need for the development of flexible and high-performance energy storage devices which can be easily integrated with wearable electronics. Among the various energy storage devices, thin and flexible supercapacitors are gaining more consideration for wearable electronics due to their salient features, such as excellent lifetime, lightweight, high power density, and their ability to deliver under mechanical deformation co...

“…Many authors found large differences in plasma parameters upon a slight change of discharge parameters due to non-linear effects, and mainly due to the influence of gaseous impurities on the plasma parameters. The interaction of gaseous plasma with polymer materials has been a subject of numerous scientific studies, and the results were found useful in the optimization of industrial-size reactors [ 8 , 9 , 10 , 11 ].…”

Fluorinated polymers are renowned for their chemical inertness and thus poor wettability and adhesion of various coatings. Apart from chemical methods employing somewhat toxic primers, gaseous plasma treatment is a popular method for the modification of surface properties. Different authors have used different plasmas, and the resultant surface finish spans between super-hydrophobic and super-hydrophilic character. Some authors also reported the hydrophobic recovery. The review of recent papers is presented and discussed. Correlations between plasma and/or discharge parameters and the surface finish are drawn and the most important conclusions are summarized. The concentration of oxygen in the surface film as probed by X-ray photoelectron spectroscopy is inversely dependent on the concentration of oxygen in gaseous plasma. The predominant mechanism leading to hydrophilic surface finish is bond scission by deep ultraviolet radiation rather than functionalization with reactive oxygen species.
