The benzotriazole (BTA)-driven graphene oxide (GO) encapsulation technique can significantly enhance the microcapsules’ overall properties, showing great potential in various fields. However, this BTA-driven GO encapsulation technique has been reported only for two-component microcapsule systems. Herein, its application in one-component microcapsule systems was studied. Three different one-component microcapsule systems have been successfully prepared by optimizing various parameters including temperature, core/wall ratio, emulsifier concentration, rotation speed, GO dosage, BTA/GO ratio, etc., by univariate experiments. Fourier transform infrared, Raman spectroscopy, X-ray photoelectron spectroscopy, scanning electron microscopy, particle size distribution, and thermogravimetric analysis demonstrated the successful preparation of the one-component microcapsules. The BTA/GO one-component microcapsules were further used in cardanol-based anticorrosion coatings. Compared with a pure biobased epoxy coating, the Z|_0.01 Hz of the composite coating has been significantly improved from 7.86 × 10⁵ Ω cm² to 3.47 × 10¹⁰ Ω cm², nearly 5 orders of magnitude. Our results demonstrated the great potential of the BTA-driven GO encapsulation technique in extrinsic self-healing.

苯并三唑驱动的氧化石墨烯包埋技术，用于具有超高性能的单组分微胶囊体系


苯并三唑 （BTA） 驱动的氧化石墨烯 （GO） 包埋技术可以显着增强微胶囊的整体性能，在各个领域显示出巨大的潜力。然而，这种 BTA 驱动的 GO 包埋技术仅报道用于双组分微胶囊系统。在此，研究了它在单组分微胶囊系统中的应用。通过单变量实验优化温度、核壁比、乳化剂浓度、转速、GO 剂量、BTA/GO 比等各种参数，成功制备了三种不同的单组分微胶囊系统。傅里叶变换红外、拉曼光谱、X 射线光电子能谱、扫描电子显微镜、粒度分布和热重分析表明单组分微胶囊的成功制备。BTA/GO 单组分微胶囊进一步用于腰果酚基防腐涂料。与纯生物基环氧涂料相比，Z|_0.01 Hz 的复合涂层已从 7.86 ×^{10 5} Ω cm² 显著提高到 3.47 ×^{10 10} Ω cm²，近 5 个数量级。我们的结果表明 BTA 驱动的 GO 封装技术在外源性自我修复中的巨大潜力。
