Preparation of polyaniline/graphene composites with excellent Anti-Corrosion properties and their application in waterborne polyurethane anticorrosive coatings
RSC Advances, 2016Co-Authors: Liu Wenjie, Ma Jianfeng, Zhongyu LiAbstract:Polyaniline, a novel conductive polymer, has been widely used as an anti-corrosive filler. In order to further improve the Anti-Corrosion performance, polyaniline/graphene (PANI/RGO) composites were prepared by in situ polymerization. And PANI/RGO composite Anti-Corrosion coatings were also prepared using PANI/RGO as anti-corrosive filler and waterborne polyurethane (WPU) as matrix. The Anti-Corrosion properties were proven by potentiodynamic polarization curves (Tafel polarization curves), electrochemical impedance spectroscopy and salt spray test analysis of the WPU anti-corrosive coatings. The results showed that the obtained composite coatings reinforced by 0.75 wt% of PANI/RGO composites possessed superior anti-corrosive performance when the graphene content of the filler was 4 wt%.

Fabrication of low-temperature curing PES coatings with excellent Anti-Corrosion properties by introducing the crosslinking agent
Corrosion Science, 2019Co-Authors: Bo Zhang, Hongyue Wang, Yizeng Di, Ye Tian, Ningning Song, Shaowei GuanAbstract:Abstract Low-temperature curing polyethersulfone (PES) coatings (LTCC-PES and LTCC-PES/PTFE) with excellent Anti-Corrosion properties have been successfully fabricated by introducing crosslinking agent. Water absorption of LTCC-PES is far lower than the common neat epoxy coatings, indicating LTCC-PES can display higher Anti-Corrosion properties. To further enhance the Anti-Corrosion properties of LTCC-PES, polytetrafluoroethylene (PTFE) is incorporated into LTCC-PES as filling agent to decrease the defects within LTCC-PES. Results show that LTCC-PES/PTFE exhibits lower water absorption and LTCC-PES/PTFE still possesses high Anti-Corrosion properties after long-term exposure to corrosive environment due to the further enhancing physical shielding effect of LTCC-PES/PTFE.

Efficient protection of Mg alloy enabled by combination of a conventional Anti-Corrosion coating and a superamphiphobic coating
Chemical Engineering Journal, 2020Co-Authors: Jinfei Wei, Lingyun Jing, Ning Tian, Xia Zhao, Junping ZhangAbstract:Abstract Magnesium (Mg) alloys have many unique properties but suffer from poor corrosion resistance. Effective Anti-Corrosion strategies are highly desirable for widespread applications of Mg alloys. Bioinspired super anti-wetting coatings are promising for metal protection, but are limited by some issues. Here, we report a bi-layer superamphiphobic coating for efficient protection of Mg alloy by sequentially spray-coating a conventional epoxy Anti-Corrosion coating and a superamphiphobic coating (perfluorodecyl polysiloxane modified SiO2). The coating showed excellent Anti-Corrosion performance owing to high superamphiphobicity and “synergistic effect” of the bi-layer structure. The coating retained excellent Anti-Corrosion performance even after 70 d immersion and 35 d neutral salt spray tests. The long-term Anti-Corrosion performance is superior to a superhydrophobic coating with similar initial Anti-Corrosion performance, and better than reported and commercial Anti-Corrosion coatings. This is because the coating maintained high superamphiphobicity in the corrosion tests owing to high chemical stability of the C-F groups and easy roll off of small NaCl drops. Hence, the contact area and contact time of NaCl on the coating are limited. So, the coating could effectively block diffusion of corrosive substances, providing long-lasting efficient protection. We believe that the strategy will shed a new light on designing novel Anti-Corrosion coatings.
