“…The presence of oxygen in the Ar plasma might be from eventual leak on the plasma chamber, from the chamber walls and mainly from the adsorbed oxygen on the NBR5080 surface. Moreover, the oxygen functionalities also might be created after the samples were contacted with air …”

In this study, first the acrylonitrile-butadiene rubber (NBR5080) was modified by argon (Ar), air, and oxygen plasma at low temperature, and the effect of plasma process (power, time, and pressure) on the surface properties of NBR5080, the interfacial properties, physical properties, and the mechanical properties of NBR5080/polytetrafluoroethylene (PTFE) composites were investigated. The state contact angle and the surface free energy were applied to characterize the surface wettability of NBR5080. The scanning electron microscope and the atomic force microscope were used to observe the surface morphology of the NBR5080. The chemical changes on the NBR5080 surface were verified by X-ray photoelectron spectroscopy. The average water contact angle the NBR5080 declined obviously when NBR5080 was treated by Ar (100 W/600 s/30 Pa). The active oxygen groups were introduced onto the surface of NBR5080 by cold plasma treatment and more active group containing oxygen were observed on the samples treated by Ar plasma. The peel strength between the NBR5080 and the PTFE was increased obviously, which increased from 0 to 44.2 N•m −1 for Ar plasma treatment. The mass and the dimension of NBR5080 increase sharply after immersing in kerosene, whereas the NBR5080/PTFE composites changed a little. The mechanical properties of NBR5080 and NBR5080/PTFE composites decreased as the immersion time in kerosene increased, but the decreased degree of NBR5080 is higher than NBR5080/PTFE composites.

“…[5][6][7][8]. The advantages of surface modification of elastomers include the preservation of useful volumetric properties of rubber along with improvement of the surface characteristics (antifriction properties, resistance to aggressive media, and ultraviolet radiation) [9][10][11]. Coatings on the rubber surface are produced in various ways: Plasmochemical treatment of elastomer surface [12,13], ion-plasma application of a metal layer [14], application of durable and wear-resistant polymers [15,16], and production of hybrid materials [17,18].…”

Two-Layer Rubber-Based Composite Material and UHMWPE with High Wear Resistance

The aim of the study is the development of two-layer materials based on ultra-high-molecular-weight polyethylene (UHMWPE) and isoprene rubber (IR) depending on the vulcanization accelerators (2-mercaptobenzothiazole (MBT), diphenylguanidine (DPG), and tetramethylthiuram disulfide (TMTD)). The article presents the study of the influence of these accelerators on the properties and structure of UHMWPE. It is shown that the use of accelerators to modify UHMWPE leads to an increase in tensile strength of 28–53%, a relative elongation at fracture of 7–23%, and wear resistance of three times compared to the original UHMWPE. It has been determined that the introduction of selected vulcanization accelerators into UHMWPE leads to an increase in adhesion between the polymer and rubber. The study of the interfacial boundary of a two-layer material with scanning electron microscopy (SEM) and infrared spectroscopy (FTIR) showed that the structure is characterized by the presence of UHMWPE fibrils localized in the rubber material due to mechanical adhesion.

“…Plasma treatment is believed to induce chemical changes such as the formation of oxygen-containing groups on the surface and changes in surface roughness [5,7,8]. These chemical reactions are very complex processes, requiring detailed and extensive experimental campaigns to optimize conditions for plasma treatment for every particular case of selected polymer and type of plasma [11]. The most studied factors impacting the effectiveness of plasma treatment are plasma power, velocity at which plasma treatment is applied, number of passes, distance between nozzle and surface and time between plasma and adhesive application [11][12][13][14].…”

In this research, Artificial Intelligence (AI) was used to support the optimization of six bonding process parameters for maximal joint strength and minimal production costs. Two industrial bonding processes were investigated, one from electronic potting and another from the manufacturing industry. The focus was on optimizing the plasma treatment of the substrate materials. Two approaches for optimization were compared, namely the traditional approach where the adhesive expert proposes experiments and interpret the results, and an AI approach with Bayesian optimization and Gaussian process models.Similar joint strengths could be achieved via the Bayesian optimization approach with 40% less budget to find the optimum compared to the traditional approach. Additionally, in the electronic potting process, the AI approach resulted in 18% reduction in production cost, while achieving a similar joint strength, compared to the traditional approach. Ageing of the samples did not result in a significant drop in joint strength nor changes in failure type or mechanism. This indicates that AI can support adhesive experts to find the optimal bonding process settings and manufacture robust and cost-efficient adhesive bonds.
