“…[38,39] Based on the characteristics of reversible repair and mild repair condition of disulfide bond, introducing reversible disulfide bonds with elastomers to prepare self-healing materials are widely used. Nevertheless, there are few studies on the self-healing properties of materials based on disulfide bond exchange reaction, especially on the self-healing kinetics of coatings under Ultra Violet (UV) light [40,41] and heating conditions. Recently, Zhao [42] introduced a disulfide bond between UV-Curable polyurethane acrylic resins, demonstrating that cracks in the cured resin material can be repaired to UV light.…”

Self-healing polymer is a kind of functional polymer materials that can repair scratches, cracks and other mechanical damage, whose unique self-healing ability is of great significance for prolonging the life of materials. Eigen self-healing polymers have become the focus of current research due to their advantages of mild healing conditions and repeatable healing. In this paper, the preparation technology and properties of self-healing elastomers were reviewed, which provided guidance for the preparation of polymers with high repair efficiency and pointed out its future development trend. The self-healing polymer materials based on Diels-Alder reaction, metal bond, hydrogen bond, ionic bond, disulfide bond, etc., are mainly introduced, and their preparation process, healing mechanism and healing properties are reviewed. Although much progress has been made in self-healing elastomers based on different dynamic bonds, the development of materials with high repair efficiency remains a huge challenge. In this paper, various repair pathways of self-healing elastomers were reviewed, which provided guidance for the balance between repair and mechanical properties. The development of inherently self-healing polymers was also prospected.

Various strategies have been developed to fabricate superhydrophobic surfaces with the guidance of adding rough micro-nano structure and decreasing surface energy. However, it is still a challenge to prepare a superhydrophobic coating with multifunction, eco-friendliness, and broad applicability to substrates. The mussel-inspired polydopamine (PDA) possessing superior material-independent adhesion was considered as the promising candidate material. Herein, a hierarchical superhydrophobic PDA coating was fabricated on Cu substrate via a facile self-assembly method. Thanks to PDA's selfroughening and self-adhesive effects, the coating obtains sufficient surface roughness and good interface adhesion. The superhydrophobic coating

“…However, there are still some problems for the reported photothermal self-healing superhydrophobic surfaces, which hinder their applications. For example, the self-healing area by near-infrared light irradiation is limited, and the self-healing time by ultraviolet irradiation is too long . Moreover, the existing photothermal self-healing superhydrophobic surfaces mainly use simulated light sources for self-healing, while those that use natural sunlight have not yet been reported.…”

Self-healing superhydrophobic coatings have a wide potential for practical applications by prolonging their lifespan, but still suffer from some shortcomings, for example, difficulty in repairing microstructure damage, limited self-healing cycles, and more importantly the inability to self-heal while in service. Herein, we present the fabrication of superhydrophobic coatings having photothermal self-healing chemical composition and microstructure for the high performance anticorrosion of Mg alloy. The coatings contain a shape-memory polymer (SMP) primer and an upper superhydrophobic coating composed of fluorinated polysiloxane-modified multiwalled carbon nanotubes (PF-POS@MWCNTs). The coatings have good superhydrophobicity, photothermal effect, and anticorrosion performance. The coatings show excellent self-healing performance in response to chemical and microstructure damage, such as rapid self-healing under 1 sun irradiation in 10 min, complete self-healing after serious damage (e.g., 10 damage and self-healing cycles and complex microstructure damage), and even self-healing under natural sunlight in 4 h. Moreover, the self-healed coatings show good corrosion protection for magnesium alloy in the neutral salt spray test. These are because of the combination of the SMP primer with good shape-memory effect and the PF-POS@MWCNTs coating with good superhydrophobicity, photothermal effect, and embedded PF-POS. The coatings are self-healable under natural sunlight while in service and thus may find applications in diverse fields.
