“…Further research should be carried out to explore the synergy between different components. In recent years, some new two-dimensional materials have been researched and prepared, such as T-type carbon [213] and phosphorene [214]. New two-dimensional materials can be explored as fillers to improve the friction and mechanical properties of composite materials.…”

Self-lubricating polymer composite coatings, with tailorable tribological and mechanical properties, have been widely employed on mechanical parts to reduce friction and wear, which saves energy and improves the overall performance for applications such as aerospace satellite parts, shafts, gears, and bushings. The addition of functional fillers can overcome the limitations of single-polymer coatings and extend the service life of the coatings by providing a combination of low friction, high wear resistance, high load bearing, high temperature resistance, and high adhesion. This paper compares the heat resistance, and the tribological and mechanical properties of common polymer matrices, as well as the categories of functional fillers that improve the coating performance. Applicable scopes, process parameters, advantages, and limitations of the preparation methods of polymer coatings are discussed in detail. The tribological properties of the composite coatings with different matrices and fillers are compared, and the lubrication mechanisms are analyzed. Fillers reduce friction by promoting the formation of transfer films or liquid shear films. Improvement of the mechanical properties of the composite coatings with fillers of different morphologies is described in terms of strengthening and toughening mechanisms, including a stress transfer mechanism, shear yielding, crack bridging, and interfacial debonding. The test and enhancement methods for the adhesion properties between the coating and substrate are discussed. The coating adhesion can be enhanced through mechanical treatment, chemical treatment, and energy treatment of the substrate. Finally, we propose the design strategies for high-performance polymer composite coating systems adapted to specific operating conditions, and the limitations of current polymer composite coating research are identified.

“…There are several surface modification methods employed in order to deposit a coating with strong adhesion onto polymer substrates. The effect of different types of surface treatments on polymeric surfaces such as mechanical (sand grit blasting), chemical (primer coating), and energetic treatment (UV/ozone radiation) on bonding strength were compared in a previous study [ 161 ]. The results showed that different surface treatments produced a variability in adhesion strength based on different polymeric systems and adhesives used.…”

The astonishing outbreak of SARS-CoV-2 coronavirus, known as COVID-19, has attracted numerous research interests, particularly regarding fabricating antimicrobial surface coatings. This initiative is aimed at overcoming and minimizing viral and bacterial transmission to the human. When contaminated droplets from an infected individual land onto common surfaces, SARS-CoV-2 coronavirus is able to survive on various surfaces for up to 9 days. Thus, the possibility of virus transmission increases after touching or being in contact with contaminated surfaces. Herein, we aim to provide overviews of various types of antiviral and antimicrobial coating agents, such as antimicrobial polymer-based coating, metal-based coating, functional nanomaterial, and nanocomposite-based coating. The action mode for each type of antimicrobial agent against pathogens is elaborated. In addition, surface properties of the designed antiviral and antimicrobial polymer coating with their influencing factors are discussed in this review. This paper also exhibits several techniques on surface modification to improve surface properties. Various developed research on the development of antiviral/antimicrobial polymer coating to curb the COVID-19 pandemic are also presented in this review.

In this study, the joining technique of two different materials such as polyvinyl chloride (PVC) and aluminum that can replace steel insertion in the PVC profile industry was investigated. The aim was to improve the interface structure for joining PVC and aluminum with different geometries on the aluminum surface. The effects of mechanical surface roughness were studied for the joining performance. Aluminum samples with mechanically deformed surfaces were prepared and joined with PVC strips. Lap-shear, interlaminar shear strength (ILSS), 3-Point (3P) bending, and coefficient of linear thermal expansion (CTE) tests were performed. Microstructural investigations were conducted with an optical microscope and scanning electron microscope. According to the results obtained, mechanical surface roughness on the aluminum improved the joining interface between PVC and aluminum. The side-punched and perforated samples achieved the best results in terms of geometrical variations on the aluminum surface. Improvement in surface roughness resulted in a 2-fold increase in lapshear shear strength and 45% reduction in 3-point bending test results. Optical microscopy was performed on the interface layer, the cavity structures were examined. In the samples with good adhesion results, it was observed that the desired locking mechanism was formed in joined structures as a result of the abrasion on the metal surface and the filling of holes with PVC.
