Published on 2025-03-06 by Xiaoxiao Peng, Haiyan Jing, Lan Yu, Zongdeng Wu, Can Su, Ziyu Ji, Junjie Shu, Hua Tang, Mingzhu Xia, Xifeng Xia, Wu Lei, Qingli Hao @MDPI
Abstract: To significantly improve the tribological performance of epoxy resin (EP), a novel h-BN/MoS2 composite was successfully synthesized using spherical MoS2 particles with lamellar self-assembly generated through the calcination method, followed by utilizing the “bridging effect” of a silane coupling agent to achieve a uniform and vertically oriented decoration of hexagonal boron nitride (h-BN) nanosheets on the MoS2 surface. The chemical composition and microstructure of[...]
Our summary: A novel h-BN/MoS2 composite was synthesized to enhance the tribological performance of epoxy resin. The uniform decoration of h-BN enhances the chemical stability of MoS2, resulting in significantly reduced friction coefficient and wear rate in EP coatings.

Photocatalytically Induced Degradation of Nano-TiO2-Modified Paint Coatings Under Low-Radiation Conditions
Published on 2025-02-27 by Maciej Kalinowski, Karol Chilmon, Justyna Kuziak, Pawe? ?ukowski, Wioletta Jackiewicz-Rek @MDPI
Abstract: Photocatalytic coatings incorporating nano-TiO2 have emerged as effective solutions for air purification, utilizing solar radiation to degrade airborne pollutants. However, the long-term stability of such coatings, particularly those based on organic binders, remains a concern due to their susceptibility to photocatalytic-driven degradation. This study investigates the effects of low-intensity UV-A irradiation (1–10 W/m2) on acrylic-based photocatalytic coatings’ stru[...]
