“…Polyvinylidenefluoride (PVDF) is a well-known polymeric precursor with highly hydrophobicity which also has excellent antioxidation and anticorrosion properties, favourable thermal stability and good mechanical behaviour [54]. Work [55] describes the fabrication and deposition of polyvinylidenefluoride (PVDF)/stearic acid (SA) nanofibres onto aluminium sheets for long-term anticorrosive protection. Pure PVDF nanofibres show a highly hydrophobic behaviour (WCA of 130 ± 1 • C), whereas the incorporation of stearic acid (SA) into the PVDF nanofibrous coating produces an enhancement in water repellence behaviour with a superhydrophobic surface (WCA of 151 ± 1 • C).…”

The use of surface engineering techniques to tune-up the composition of nanostructured thin-films for developing functional coatings with advanced properties is a hot topic within the scientific community. The control of the coating structure at the nanoscale level allows improving the intrinsic properties of the surface compared to bulk materials. A nanodeposition technique with increasing popularity in the field of nanotechnology is electrospinning. This technique permits the fabrication of long and continuous fibres on the micro-nano scale. The good control over fibre morphology combined with its simplicity, cost-effectiveness, easy exploitability and scalability make electrospinning a very interesting tool for technological applications. This review is focused on the use of the electrospinning technique to protect metallic surfaces against corrosion. Polymeric precursors, from natural or biodegradable to synthetic polymers and copolymers can be electrospun with an adequate control of the operational deposition parameters (applied voltage, flow rate, distance tip to collector) and the intrinsic properties of the polymeric precursor (concentration, viscosity, solvent). The electrospun fibres can be used as an efficient alternative to encapsulate corrosion inhibitors of different nature (inorganic or organic) as well as self-healing agents which can be released to reduce the corrosion rate in the metallic surfaces.

“…Among these versatile processes, electrospinning is a currently low‐cost, simple and effective technique providing the synthesize fibers with well‐controlled size distribution, morphology, surface chemistry, and average diameter within submicron‐micrometer range. The technique is applied to not only polymeric (with natural or synthetic origins) but also inorganic (metals, ceramics, and glasses) materials, in particular textiles, medicine, environmental remediation, electronics, sensor technology, filtration, and anticorrosion coating fields. There is a serial variable to be noted in the electrospinning process; (1) process parameters (feed rate, accelerating voltage, tip‐to‐target distance, and needle diameter), (2) solution parameters (solvent, molecular weight, viscosity, polymer concentration, and solution conductivity), and (3) environmental parameters (temperature, pressure, and relativity humidity).…”

Uniform beadless fibers of chlorinated polypropylene (PP-Cl) are prepared by electrospinning of PP-Cl solutions in tetrahydrofuran at different concentrations, feed rates, applied voltages, and tip-to-collector distances (TCDs) under ambient conditions for the first time. Average fiber diameter and morphology of the electrospun PP-Cl fibers are determined by scanning electron microscopy. On the other hand, the wettability of the fibers is examined by water contact angle (WCA) measurements. Furthermore, thermal behavior of fibers is investigated by differential scanning calorimetry and thermogravimetric analyses, respectively. Obtained results show that the higher concentrations and feed rates of polymer solutions not only enhance the average diameter of the electrospun fibers ranging from 2.2 AE 0.5 to 2.8 AE 0.3 μm but improve the hydrophobicity of the fiber surfaces from 128 AE 1.1 to 141 AE 1.0 as well. On the other hand, when applied voltage is increased or TCD is decreased, diameters of achieved fibers are enhanced. It is suggested that PP-Cl is an useful material for solution electrospinning process at under ambient conditions, exhibiting great scientific merit and good industrial expectation in the potential PP applications.

“…Other aspect to be remarked is that the implementation of superhydrophobic surfaces also can be used as a great potential for applications of anticorrosive protection and, due to this, several research papers are focused on the fabrication of superhydrophobic electrospun fiber-coated metal substrates with a long-time corrosion resistance [21,22]. More recent research has been based on the immobilization of corrosion inhibitors into the electrospun fibers for improving the corrosion resistance.…”

A Comparative Study of Multifunctional Coatings Based on Electrospun Fibers with Incorporated ZnO Nanoparticles

In this work, polymeric fibers of polystyrene (PS) with incorporated ZnO nanoparticles have been deposited onto an aluminum alloy substrate (6061T6) by using the electrospinning technique. In order to optimize the deposition process, the applied voltage and flow rate have been evaluated in order to obtain micrometric electrospun fibers with a high average roughness and superhydrophobic behavior. Thermogravimetric analysis (TGA) has also been employed in order to corroborate the amount of ZnO incorporated into the electrospun fibers, whereas differential scanning calorimetry (DSC) has been performed in order to determine the glass transition temperature (T g ) of the polymeric electrospun fibers. In addition, a specific thermal treatment (T g + 20 • C) of the synthesized electrospun fibers has been evaluated in the resultant corrosion resistance. A comparative study with previously reported results corresponding to polyvinyl chloride (PVC) fibers is carried out along this paper to show the changes in behavior due to the different compositions and fiber diameters. The coating has produced an important reduction of the corrosion current of the aluminum substrate in two orders of magnitude, showing also an important enhancement against pitting corrosion resistance. Finally, this deposition technique can be used as an innovative way for the design of both superhydrophobic and anticorrosive surfaces in one unique step over metallic substrates with arbitrary geometry.
