AbstractIn this paper, the superhydrophobic poly(vinylidene fluoride)/fluorinated ethylene propylene/SiO2/CNTs-EDTA (PFSC-EDTA) composite coating was successfully fabricated and applied for anti-scaling performance. The deposition of CaCO3 on the surface of the superhydrophobic PFSC-EDTA composite coating reached 0.0444 mg/cm2 for 192-h immersion into the supersaturated CaCO3 solution, which was only 11.4% that of the superhydrophobic PFSC composite coating. At the interface between the CaCO3 solution and the PFSC-EDTA coating, the Ca2+ could be firstly chelated by EDTA that was benefit for improving the anti-scaling performance of the superhydrophobic PFSC-EDTA composite coating. In another hand, the addition of EDTA to the CNTs played an important role in fabricating the SiO2-centric and CNTs-EDTA-surrounded multilevel micro–nanostructure in the superhydrophobic PFSC-EDTA composite coating, in favor of maintaining the air film under the water and the stability of the superhydrophobic surface. The research supplies a new way of improving anti-scaling performance of superhydrophobic coating by incorporating the organic chelating agent at the interface and changing the traditional way of scale prevention.

Fluoropolymers have had a profound effect on all aspects of industry since their discovery during the 1930s. This review briefly describes the historical development of the fluoropolymer industry, with a focus on traditional fluoroplastics, and lists the major industrial and commercial materials currently in use. These include polytetrafluoroethylene (PTFE, Teflon), polychlorotrifluoroethylene (PCTFE), fluorinated ethylene propylene (FEP), the ethylene copolymer of tetrafluoroethylene (ETFE), the ethylene copolymer of chlorotrifluoroethylene (ECTFE), perfluoroalkoxy (PFA), polyvinylfluoride (PVF), polyvinyldifluoride (PVDF), Nafion, fluoroethylenevinylether (FEVE), a semicrystalline three component terpolymer of tetrafluoroethylene, hexafluoropropylene, and vinylidene fluoride (THV), Teflon-AF, Cytop, and Hyflon. The production, processing, and properties of these fluoropolymers are discussed, together with examples of the specific uses in chemical industry, manufacturing, electronics, architecture, energy, health and domestic sectors. Other related fluoropolymers such as fluoroelastomers, perfluoropolyethers, and fluorosurfactants are briefly mentioned. Environmental aspects of fluoropolymers are considered as is the current state of the fluoropolymer industry.

The study examined the wear resistance of Al2O3/epoxy resin composite coating including the composite curing agents and its ratio,fillers volume fraction and its particle size.The results show that, firstly, when the low molecular polyamide and phenolic amine composite curing agent were added into the epoxy resin system within a proper ratio ,it can improve the coating wear resistance property, especially the quality ratio is 1:1. Secondly, when the fillers particle size is fixed, its volume fraction ranges from 0 to 36.8%, when the volume fraction is 23.4%, the wear resistance property is better. Thirdly, when the fillers volume fraction is fixed, its particle size ranges from 28μm to 106μm, when the size within the range of 58-75μm, it can significantly improve the wear resistance ,the best wear resistance is about 3 or 5 times of the basal material Q235,having a higher cost performance. Besides, the coating resistance mechanism was investigated.
