摘要

本研究通过原位电化学聚合合成了掺杂氧化石墨烯、钼酸盐和水杨酸盐(PPy/GO/Mo/Sal)的聚吡咯基纳米复合材料,以提高聚合物涂层的防腐蚀保护性能。通过扫描电镜、电离辐射X、傅立叶变换红外光谱、拉曼光谱和 XRD 对涂层的形貌和结构进行了表征。在 0.1 M NaCl 溶液中通过 EIS 电位极化、盐雾试验和开路电位(OCP)测量研究了涂层的防腐蚀能力。结果表明,在 PPy 基体中同时含有钼酸盐/水杨酸盐和 GO 的情况下,纳米复合材料涂层对低碳钢的腐蚀具有优异的防护能力,优于仅以 GO 作为填料的涂层。与只掺杂水杨酸盐或水杨酸盐/GO 的纳米复合材料相比,同时掺杂钼酸盐/水杨酸盐和 GO 的纳米复合材料在 OCP 时间曲线上表现出最长的保护高原(约 100 小时),并伴有一些波动点,这就是钼酸盐掺杂剂的自修复作用。这还导致腐蚀电流减小(Tafel 图)、阻抗升高(Bode 图)以及在盐雾试验中具有更好的保护性能。在这种情况下,涂层的防腐蚀能力是通过屏障和自修复机制实现的。

Polypyrrole-based nanocomposites doped with both salicylate/molybdate and graphene oxide for enhanced corrosion resistance on low-carbon steel.

Polypyrrole-based nanocomposites doped with both salicylate/molybdate and graphene oxide for enhanced corrosion resistance on low-carbon steel.

In this work, polypyrrole-based nanocomposites doped with graphene oxide, molybdate, and salicylate (PPy/GO/Mo/Sal) were synthesized via in situ electrochemical polymerization to enhance the anti-corrosion protection performance of polymer coatings. The morphology and structures of the coatings were characterized by SEM, EDX, FTIR, Raman spectroscopy, and XRD. The protection abilities of coatings against corrosion were investigated in 0.1 M NaCl solution with EIS potentiodynamic polarization, salt spray test, and open-circuit potential (OCP) measurements. The results showed that with the presence of both molybdate/salicylate and GO in the PPy matrix, the nanocomposite coating exhibited an excellent protection ability against corrosion for low-carbon steel, better than that with only GO as filler. Compared to the nanocomposites doped with only salicylate or salicylate/GO, the one doped with both molybdate/salicylate and GO exhibited the longest protection plateau (ca. 100 h) on the OCP-time curves with some fluctuation points known as the self-healing action of molybdate dopant. It also resulted in a decrease in the corrosion current (Tafel plots), a higher impedance (Bode plot), and a better protection performance in salt spray tests. In this case, the anti-corrosion ability of the coatings was provided through a barrier and self-healing mechanism.

期刊介绍: Designed Monomers and Polymers ( DMP) publishes prompt peer-reviewed papers and short topical reviews on all areas of macromolecular design and applications. Emphasis is placed on the preparations of new monomers, including characterization and applications. Experiments should be presented in sufficient detail (including specific observations, precautionary notes, use of new materials, techniques, and their possible problems) that they could be reproduced by any researcher wishing to repeat the work. The journal also includes macromolecular design of polymeric materials (such as polymeric biomaterials, biomedical polymers, etc.) with medical applications. DMP provides an interface between organic and polymer chemistries and aims to bridge the gap between monomer synthesis and the design of new polymers. Submssions are invited in the areas including, but not limited to: -macromolecular science, initiators, macroinitiators for macromolecular design -kinetics, mechanism and modelling aspects of polymerization -new methods of synthesis of known monomers -new monomers (must show evidence for polymerization, e.g. polycondensation, sequential combination, oxidative coupling, radiation, plasma polymerization) -functional prepolymers of various architectures such as hyperbranched polymers, telechelic polymers, macromonomers, or dendrimers -new polymeric materials with biomedical applications
