Abstract Microcapsules containing linseed oil were synthesized by in situ polymerization method and benzotriazole was entrapped between polyelectrolytes layers assembled outside the microcapsules, using the Layer-by-Layer technique. The prepared microcapsules presented mean number diameter of 2.08 μm and released greater amount of benzotriazole in slightly acidic NaCl solution. The corrosion protection effect of the microcapsules was evaluated using a carbon steel substrate coated with an epoxy resin loaded with the microcapsules (4.8 wt%). Electrochemical impedance spectroscopy demonstrated the best performance of the loaded coating when compared to a control due to the stimuli-responsive release of linseed oil and benzotriazole.

基于含有亚麻籽油和苯并三唑的双刺激响应微胶囊的智能涂层，用于主动腐蚀保护

摘要 采用原位聚合法合成了含有亚麻籽油的微胶囊，并采用逐层技术将苯并三唑包裹在微胶囊外组装的聚电解质层之间。制备的微胶囊平均数径为 2.08 μm，在微酸性 NaCl 溶液中释放出更多的苯并三唑。使用负载有微胶囊（4.8wt%）的环氧树脂涂覆的碳钢基材来评估微胶囊的腐蚀保护效果。由于亚麻籽油和苯并三唑的刺激响应性释放，电化学阻抗谱证明负载涂层与对照相比具有最佳性能。
