Abstract

Preparing polymeric coatings with well corrosion resistance and high thermal conductivity (TC) to prolong operational life and ensure service reliability of heat conductive metallic materials has long been a substantive and urgent need while a difficult task. Here we report a multifunctional epoxy composite coating (F-CB/CEP) by synthesizing cerium methacrylate and ingeniously using it as a novel curing agent with corrosion inhibit for epoxy resin and modifier for boron nitride through "cation-π" interaction. The prepared F-CB/CEP coating presents a high TC of 4.29 W m⁻¹ K⁻¹, which is much higher than other reported anti-corrosion polymer coatings and thereby endowing metal materials coated by this coating with outstanding thermal management performance compared with those coated by pure epoxy coating. Meanwhile, the low-frequency impedance remains at 5.1 × 10¹¹ Ω cm² even after 181 days of immersion in 3.5 wt% NaCl solution. Besides, the coating also exhibits well hydrophobicity, self-cleaning properties, temperature resistance and adhesion. This work provides valuable insights for the preparation of high-performance composite coatings with potential to be used as advanced multifunctional thermal management materials, especially for heat conduction metals protection.

甲基丙烯酸铈辅助制备高导热防腐蚀多功能热传导金属防护涂料。

制备具有良好耐蚀性和高导热性的聚合物涂层，以延长导热金属材料的使用寿命和保证其使用可靠性，是一项现实而迫切的任务，也是一项艰巨的任务。本文报道了合成甲基丙烯酸铈并巧妙地将其作为新型固化剂，通过阳离子-π相互作用对环氧树脂具有抑制作用，并对氮化硼具有改性作用，制备了多功能环氧复合涂层(F-CB/CEP)。制备的F-CB/CEP涂层具有4.29 W m-1 K-1的高TC，远高于已有报道的其他防腐聚合物涂层，因此与纯环氧涂层相比，该涂层涂层的金属材料具有出色的热管理性能。同时，在3.5 wt% NaCl溶液中浸泡181天后，其低频阻抗仍保持在5.1 × 1011 Ω cm2。此外，该涂层还具有良好的疏水性、自洁性、耐温性和附着力。该研究为高性能复合涂层的制备提供了有价值的见解，具有作为先进多功能热管理材料的潜力，特别是在导热金属保护方面。

期刊介绍： Nano-Micro Letters is a peer-reviewed, international, interdisciplinary and open-access journal that focus on science, experiments, engineering, technologies and applications of nano- or microscale structure and system in physics, chemistry, biology, material science, pharmacy and their expanding interfaces with at least one dimension ranging from a few sub-nanometers to a few hundreds of micrometers. Especially, emphasize the bottom-up approach in the length scale from nano to micro since the key for nanotechnology to reach industrial applications is to assemble, to modify, and to control nanostructure in micro scale. The aim is to provide a publishing platform crossing the boundaries, from nano to micro, and from science to technologies.
