Abstract

A multifunctional epoxy resin (EP) coating reinforced with nitrogen-doped carbon dots (N-CDs) anchored on Ti₃C₂T_x MXene nanosheets (CDs@Ti₃C₂T_x) was developed to address the rapid oxidation and limited functionality of conventional MXene. The hybrid filler, synthesized via a one-step hydrothermal process, imparted oxidation resistance, anticorrosion, lubricity, and enhanced barrier properties. As a result, the as-prepared CDs@Ti₃C₂T_x/EP coating could exhibit an outstanding long-term corrosion resistance, maintaining a low-frequency impedance of 1.38 × 10¹¹ Ω·cm² after 70 days in 3.5 wt% NaCl, along with excellent tribological performance, achieving a friction coefficient of 0.234 and ultralow wear rate (4.87 ×10⁻⁴ mm³/Nm). This strategy offers a promising route for durable protection of marine infrastructure.

通过cd锚定Ti3C2Tx MXene对CDs@Ti3C2Tx/EP复合涂层进行定制润滑和防腐

为了解决传统MXene快速氧化和功能受限的问题，在Ti3C2Tx MXene纳米片（CDs@Ti3C2Tx）上锚定氮掺杂碳点（N-CDs）增强多功能环氧树脂（EP）涂层。该杂化填料通过一步水热法合成，具有抗氧化、防腐、润滑和增强阻隔性能。结果表明，制备的CDs@Ti3C2Tx/EP涂层具有优异的长期耐蚀性，在3.5 wt% NaCl环境下，70天后保持1.38 × 1011 Ω·cm2的低频阻抗，同时具有优异的摩擦学性能，摩擦系数为0.234，磨损率为4.87 ×10−4 mm3/Nm。这一战略为持久保护海洋基础设施提供了一条有希望的途径。

期刊介绍： Tribology is the science of rubbing surfaces and contributes to every facet of our everyday life, from live cell friction to engine lubrication and seismology. As such tribology is truly multidisciplinary and this extraordinary breadth of scientific interest is reflected in the scope of Tribology International. Tribology International seeks to publish original research papers of the highest scientific quality to provide an archival resource for scientists from all backgrounds. Written contributions are invited reporting experimental and modelling studies both in established areas of tribology and emerging fields. Scientific topics include the physics or chemistry of tribo-surfaces, bio-tribology, surface engineering and materials, contact mechanics, nano-tribology, lubricants and hydrodynamic lubrication.
