摘要

以卡双酚（CBP）为基的聚苯并恶嗪（CBPA-PBz）为基体，通过原位聚合酯化反应与酸酐、二羧酸等交联剂进行杂化，降低游离羟基。根据我们之前的报道，以腰果酚和苯甲醛为原料合成了CBP，然后以苯胺和多聚甲醛为原料，通过曼尼希缩合转化为苯并恶嗪（CBPA-Bz）单体。用等摩尔比的六种不同交联剂配制了CBPA-Bz，并在高温下进行了聚合。这提供了一个高度交联的聚苯并恶嗪网络以及CLs骨架，通过与苯并恶嗪单元在固化过程中产生的游离羟基形成酯键。6种CBPA-CL-PBz基体均具有超疏水（WCA≥150°）和良好的防腐性能，特别是CBPA-DSA-PBz对低碳钢表面的缓蚀效率达到99%以上。

A novel cross-linked card-bisphenol based polybenzoxazine approach: Enhanced superhydrophobic and anticorrosive coatings

To reduce the free hydroxyl groups of card-bisphenol (CBP) based polybenzoxazine matrix (CBPA-PBz), hybridized with various cross-linkers, such as anhydride and dicarboxylic acid through esterification by in-situ polymerization. The CBP was synthesized using cardanol and benzaldehyde as per our earlier report, then it was converted into benzoxazine (CBPA-Bz) monomer using aniline and paraformaldehyde through Mannich condensation. The CBPA-Bz was formulated with equal mole ratios of six different cross-linkers (CLs), and it was polymerized at high temperature. This offers a highly cross-linked polybenzoxazine network along with the skeleton of CLs via the formation of ester linkages with free hydroxyl groups generated by the benzoxazine unit during the curing process. All six CBPA-CL-PBz matrices possess superhydrophobic (WCA ≥150°) and good anticorrosion behaviors particularly the CBPA-DSA-PBz, which exhibits above 99 % corrosion inhibition efficiency towards the protection of mild steel surfaces.
