Summary: Polymer coatings have gained attention due to their low cost, ease of coating, low friction, and good anti-corrosion properties. Among various polymers, UHMWPE stands out for its excellent tribological properties, despite limitations such as low load-bearing capacity and low thermal stability. Researchers have developed various routes, including composite coatings, film systems, and dual film systems, to improve the tribological performance of UHMWPE coatings.

Summary: This study investigates the tribological performance of (Ta/ZrN)(n) multilayer coatings against ultrahigh molecular weight polyethylene (UHMWPE) material. The results show that (Ta/ZrN)(n) multilayer coatings exhibit improved wear resistance and low coefficient of friction under an applied load of 1 N. The multilayer coating with the thinnest ZrN as the topmost layer of 100 nm demonstrates high hardness, excellent biotribological properties, and low residual stresses.

Summary: In this study, wear resistant coatings, including hydroxyapatite (HAp) and reduced graphene oxide (rGO), were applied to polyetheretherketone (PEEK) sample through dip coating method. It was found that adding rGO enhanced the friction and wear resistance of the coating, with HAp+rGO composite achieving the best wear resistance. Furthermore, rGO acted as an interstitial bonding agent between PEEK and HAp, increasing bond strength.

Summary: This work investigates the microstructure, phase composition, mechanical and tribological properties of WN-based nanocomposite multilayers with a second MeN (Me = Zr, Cr, Mo, Nb) layer. WN/MoN multilayers were studied for the first time using cathodic-arc physical vapor deposition (CA-PVD). First-principles calculations were also performed to gain more insight into the properties of the deposited multilayers. Among the four studied systems, WN/NbN showed the best performance as a protective coating in challenging conditions.

Summary: Four novel bis-chalcone-based carbazole derivative photoinitiators were designed and synthesized in this study. Their maximum absorption wavelengths were determined and found to exhibit high molar extinction coefficients. Furthermore, a three-component photoinitiation system including bis-chalcone/iodonium/amine was successfully used to trigger the rapid and efficient photopolymerization of acrylates. The photoinitiators also showed good photo bleaching and biocompatibility, making them suitable for applications such as 3D printing and deep coating curing.

Summary: In this study, 2-amino-5 mercapto-1,3,4-thiadiazole (ATT) was used as an intercalating agent to prepare ATT/BNNS nanofillers via a liquid-phase assisted ultrasound method. TEM results showed that ATT successfully exfoliated BNNS and reduced agglomeration. The WEP ATT/BNNS coating exhibited the best protective performance under saline immersion due to the combined action of ATT inhibitor and BNNS physical barrier.
