“…The results corroborate that the self-healing electrospun coating has lower corrosion current in comparison with control sample, resulting in 88% corrosion inhibition efficiency. A similar approach is presented in [69] where a pH-responsible self-healing core-shell electrospun nanofibres coating encapsulating oleic acid (OA) and benzotriazoles (BTA) is used for corrosion protection of carbon steel. In this work, the shell of electrospun nanofibres is PVA, whereas the healing agents OA and BTA are used as core materials to reseal a damaged region.…”

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.

An overview of recent advances related to self‐healing (SH) of materials and solution electrospinning (SEP) is provided. SH agents (SHAs) in electrospun form seems to be one of the most promising approaches for SH and exhibit an increasing trend for a wide range of applications. The aim of the current review paper is to report contributions and advances related to SH of materials by using SHAs in electrospun form and provide insights for further improvement of this promising technology. More specifically, this paper contains investigations in which the SHAs or the SHA containers were exclusively prepared by SEP.

Nanofibrous Patches for Repairing Cracked Surfaces

Crack repairing aims at reducing crack propagation to maintain the mechanical properties and extend the lifetime of materials. Self‐healing materials require the presence of fillers containing healing agents or a material's matrix with an intrinsic healing ability. A “patch‐and‐heal” strategy is proposed here to repair small cracks on existing materials. First, nanofibrous patches encapsulating photoinitiators or catalysts are fabricated by electrospinning. Then, small cracks are covered with flexible nanofibrous patches containing a photoinitiator or a photocatalyst. After dropping monomers on the patches, a polymer film and a foam are formed rapidly after UV‐irradiation or a thermal treatment, respectively. The “patch‐and‐heal” strategy is therefore a promising concept for repairing small cracks in a rapid and convenient manner.
