通过修饰SiO2纳米颗粒（SNP）的表面功能来控制聚苯并恶嗪/SiO2纳米复合涂层中两相之间的界面相互作用。本工作制备了表面带有甲基、环氧基和苯并恶嗪基团的SNPs，并通过FTIR、TGA和元素分析对其进行了表征。在固化过程中，环氧基团或苯并恶嗪基团与苯并恶嗪分子发生反应，使纳米粒子与苯并恶嗪分子之间形成了较强的化学键合。采用SEM、EDS、水接触角测量和交流阻抗技术对复合镀层的表面性能和耐蚀性进行了研究。在3.5wt%NaCl水溶液中浸泡31 d后，其电荷转移电阻均超过1G Ω cm 2，是纳米复合涂层的3个数量级。
The interfacial interaction between the two phases in polybenzoxazine/SiO2 nanocomposite coatings was controlled through modifying surface functionalities of SiO2 nanoparticles (SNP). SNPs with methyl, epoxide, and benzoxazine groups on the surface were prepared in this work, which was characterized by FTIR, TGA, and elemental analysis. The strong chemical bonding between nanoparticles and polybenzoxazine was obtained because of the reaction between epoxide groups or benzoxazine groups and benzoxazine molecular during the curing process. Both surface properties and corrosion resistance of composite coatings were fully investigated with the assistance of SEM, EDS, water contact angle measurement, and EIS technique. SNP incorporation could reduce porosity of the coatings so significant that all SNP loading nanocomposite coatings exhibited excellent corrosion resistance with a charge transfer resistance of over 1 GΩ cm2 during 31 days’ immersion in a 3.5 wt % NaCl aqueous solution, which was 3 orders of magn...
