Abstract

Metal corrosion leads to structural degradation, safety risks, and economic losses, necessitating the development of advanced anticorrosion coatings. Conventional organic coatings often rely on fossil-based thermosetting resins and solvent-based processing, causing environmental concerns and coating defects. In this study, a bio-based, solvent-free, UV-curable smart anticorrosion coating was developed using a novel epoxidized soybean oil-based resin (IESO) with superior mechanical strength, thermal stability, and volatile organic compounds (VOCs) -free characteristic. To enhance anti-corrosion performance and thermal conductivity, hexagonal boron nitride (h-BN) was first hydroxylated to obtain hydroxylated boron nitride (OBN), which was then functionalized with tannic acid (TA) and Zn^2 + to form TA-Zn-OBN through synergistic hydrogen bonding and π–π* interactions. This functional filler improves dispersion, interfacial compatibility, and introduces a multi-responsive self-healing mechanism. Subsequently, a multifunctional coating (TA-Zn-OBN/IG40) was prepared using a mixture of IESO and diluted (GAGM) as the matrix (IG40) and TA-Zn-OBN as the filler. The developed coating exhibits multiple anti-corrosion mechanisms, self-healing capability, and advanced thermal management, providing a sustainable and effective solution for corrosion protection of electronic devices.

生物基环保涂料，具有多机制防腐设计和先进的导热性

金属腐蚀会导致结构退化、安全风险和经济损失，因此需要开发先进的防腐涂料。传统的有机涂料通常依赖于化石基热固性树脂和溶剂型加工，造成环境问题和涂层缺陷。本研究采用一种新型环氧大豆油基树脂（IESO）开发了一种生物基、无溶剂、可紫外光固化的智能防腐涂料，该树脂具有优异的机械强度、热稳定性和无挥发性有机化合物（VOCs）的特性。为了提高抗腐蚀性能和导热性，首先将六方氮化硼（h-BN）羟基化得到羟基化氮化硼（OBN），然后与单宁酸（TA）和Zn2 +进行官能化，通过协同氢键和π -π *相互作用形成TA- zn -OBN。这种功能性填料改善了分散性、界面相容性，并引入了多响应自修复机制。随后，以IESO和稀释后的混合物（GAGM）为基体（IG40）， TA-Zn-OBN为填料制备了多功能涂层（TA-Zn-OBN/IG40）。该涂层具有多种防腐机制、自愈能力和先进的热管理，为电子器件的防腐提供了可持续有效的解决方案。
