为提高聚苯胺(PANI)/聚氨酯(PU)涂层对腐蚀介质的物理屏障性能,引入二维片层材料是有效方法之一。以2, 4-二异氰酸甲苯酯(TDI)和3,3′-二氯-4,4′-二氨基二苯基甲烷(MOCA)为原料合成聚氨酯(PU)涂层基体,将PANI与二维Ti_3C_2Tx进行插层反应制成MXene@PANI复合物,再将MXene@PANI添加到PU树脂中,得到MXene@PANI/PU防护涂层。结果表明:MXene/PANI质量比为1∶1时,经盐雾实验60天后MXene@PANI/PU涂层表面无明显腐蚀现象,腐蚀电流为3.709×10~(-9) A·cm~(-2),阻抗模值为1.93×10~8 Ω·cm~2。这归因于一方面MXene改善PANI的电化学活性,提高PANI的电化学防腐蚀性能;另一方面,Ti_3C_2Tx纳米片可作为二维屏障,抑制腐蚀性介质进入涂层内部,提高其长效防护性能。 |

In order to enhance the physical barrier performance of polyaniline(PANI)/polyurethane(PU) coating against corrosive medium, the introduction of two-dimensional material in the coating is one of the effective methods. PU coating matrix was synthesized from 2,4-diisocyanate (TDI) and 3,3′-dichloro-4, 4′-diamino diphenylmethane(MOCA),and MXene@PANI was synthesized by intercalation reaction of PANI with Ti_3C_2Tx.Then protective coating of MXene@PANI/PU was obtained by adding MXene@PANI into PU.The results show that when the mass ratio of MXene/PANI is 1∶1, no obvious corrosion occurs on the surface of the MXene@PANI/PU coating after 60 days of salt spraying.The corrosion current is 3.709×10~(-9) A·cm~(-2), and the impedance modulus is 1.93×10~8 Ω·cm~2.The reason is that MXene improves the electrochemical activity of PANI and thus enhances the electrochemical anticorrosion performance of PANI.On the other hand, MXene nanoplates as a two-dimensional barrier can prevent the corrosive medium from entering into the coating, which improves the long-term protective performance of the coating. |
