“…SHSMs create more potential to increase the service life and reliability of protective coatings. Thus, SH silicone rubbers based on the covalent and non-covalent reversible interactions (imine, disulfide, boroxine, carbamate, hydrogen, ionic and coordination bonds) were utilized to prepare various types of protection coatings, including anticorrosion films [ 53 , 54 , 110 , 120 , 125 , 139 , 144 ], antifouling and antimicrobial coatings [ 20 , 100 , 104 , 106 , 120 , 145 ], insulators [ 44 , 60 , 154 ], films with SH ability after electrical breakdown [ 7 , 8 , 9 , 60 , 61 , 108 ], anti-icing [ 121 ], and superhydrophobic coatings [ 26 , 52 , 119 , 155 ]. Thus, there are no specific formulas related to protective coatings, as the composition and properties of the coating will vary depending on the specific application.…”

“…Special attention should be paid to obtaining superhydrophobic coatings [ 26 , 76 , 119 , 155 ] as well as to corrosion protection [ 117 ] and anti-icing [ 52 ]. Since superhydrophobic coatings are susceptible to stress due to the fragility of their structure, resulting in reduced superhydrophobic and anti-icing performance, in 2022–2023 some reports proposed a new insight to improve durability.…”

This review is dedicated to self-healing silicone materials, which can partially or entirely restore their original characteristics after mechanical or electrical damage is caused to them, such as formed (micro)cracks, scratches, and cuts. The concept of self-healing materials originated from biomaterials (living tissues) capable of self-healing and regeneration of their functions (plants, human skin and bones, etc.). Silicones are ones of the most promising polymer matrixes to create self-healing materials. Self-healing silicones allow an increase of the service life and durability of materials and devices based on them. In this review, we provide a critical analysis of the current existing types of self-healing silicone materials and their functional properties, which can be used in biomedicine, optoelectronics, nanotechnology, additive manufacturing, soft robotics, skin-inspired electronics, protection of surfaces, etc.

“…Microencapsulated lubricants filled with polymers are a promising solution. Microencapsulation technology has been widely used in the fields of selflubrication, 10,11 self-healing, [12][13][14] phase change mat erials, 15,16 and flame retardant materials, 17 etc. Filling the polymer with microcapsules loaded with liquid lubricant can effectively improve its tribological properties.…”

Cured epoxy resins have poor abrasion resistance, which shortens the service life of the material. This work aims to improve the tribological properties of epoxy resins by coupling self‐lubrication and auto‐healing. In this study, linseed oil microcapsules with an average particle size of 38.57 μm and good thermal stability were successfully prepared by in situ polymerization. The effects of microcapsule content on the tribological, mechanical, and self‐healing properties of the composite coatings were studied. It was demonstrated that the composite coating has outstanding self‐lubricating properties. The coefficient of friction reduced from 0.634 (pure epoxy resin) to 0.0459 (epoxy resin with 10 wt.% linseed oil microcapsules). Wear rate reduced from 7.16 × 10−4 mm3/(N m) to 1.74 × 10−5 mm3/(N m). The self‐lubricating mechanism of the coating was investigated by SEM and EDS, which indicated that the formation of uniform and continuous lubricating film on the surface of the friction pairs was the key to improving the wear resistance of the material. In addition, the linseed oil released after the microcapsules rupture can repair the abrasion marks by reacting with oxygen during the friction process. The dual‐functional effect of linseed oil microcapsules prolongs the life of epoxy resin coating and expands its application range.

“…Structural healing is to recover the mechanical properties of the load-bearing materials, 4,5 while functional healing mainly repairs the certain function of functional materials, 6 such as the barrier function to media like water, gas, solvents, and so forth, the electrical conductivity, 7 and the interface properties like the hydrophobicity. 8 Among the functional-healing materials, the selfhealing anticorrosion coating is the most studied and fastest-growing self-healing material. [9][10][11] Therefore, it is also considered to be a self-healing material that is most likely to be the first to realize practical application.…”

Attributed to the merits of excellent material compatibility, healing performance, and long‐term stability, the self‐healing system based on microencapsulated epoxy‐amine chemistry is a potentially practical self‐healing system for both structural and functional materials. Herein, based on the microencapsulated epoxy‐amine chemistry, a self‐healing anticorrosion coating was successfully developed. This self‐healing coating system was modeled theoretically to explore the factors that influence the crack filling and the self‐healing anticorrosion function. The established quantitative relationship shows that the filling depth of the crack in the coating is proportional to the microcapsule parameters and coating thickness, but inversely proportional to the crack width. Based on the above theoretical model, the effects of various parameters on the anticorrosion performance were experimentally studied. The actual filling of small in‐situ cracks (<100 μm) generated by impact damage was semi‐quantitatively characterized using scanning electron microscopy (SEM). The filling behavior is consistent with the theoretical modeling. After being healed at room temperature for 2 days upon impact damage, the formulated self‐healing coatings were subjected to accelerated corrosion tests in 10 wt% sodium chloride (NaCl) solution for 2 days to observe their anticorrosion behavior. Compared to the neat epoxy coating, all the formulated self‐healing epoxy coatings show evident anticorrosion function. Good self‐healing anticorrosion performance was achieved by adding 10.0 wt% microcapsules with a size of 100–150 μm to the coating with a thickness of 300 μm. The results of this investigation laid a theoretical and technical foundation for the further development of both the self‐healing chemistry and the self‐healing anticorrosion coating.
