Polymer materials are vulnerable to damages, failures, and degradations, making them economically unreliable. Self-healing polymers, on the other hand, are multifunctional materials with superior properties of autonomic recovery from physical damages. These materials are suitable for biomedical and tissue engineering in terms of cost and durability. Schiff base linkages-based polymer materials are one of the robust techniques owing to their simple self-healing mechanism. These are dynamic reversible covalent bonds, easy to fabricate at mild conditions, and can self-reintegrate after network disruption at physiological conditions making them distinguished. Here we review self-healing polymer materials based on Schiff base bonds. We discuss the Schiff base bond formation between polymeric networks, which explains the self-healing phenomenon. These bonds have induced 100% recovery in optimal cases.

“…Biofouling of immersed artificial facilities is the accumulation and growth of unwanted biomolecules and organisms on surfaces through a dynamic process with considerable consequences [ 1 , 2 ], which is devastating for the ecological and economic status of the ocean industry [ 3 , 4 ]. Biofouling slows the speed of the ship hull with increasing fuel consumption and greenhouse gas emissions [ 5 ].…”

Copolymers containing MQ silicone and acrylate were synthesized by controlling the additive amount of compositions. Subsequently, fouling release coatings based on the copolymer with the incorporation of non-reactive phenylmethylsilicone oil were prepared. The surface properties of the coating (CAMQ40) were consistent with that of the polydimethylsiloxane (PDMS) elastomer, which ensured good hydrophobicity. Moreover, the seawater volume swelling rate of all prepared coatings was less than 5%, especially for CAMQ40 with only 1.37%. Copolymers enhanced the mechanical properties of the coatings, while the enhancement was proportional to the molar content of structural units from acrylate in the copolymer. More importantly, the adhesion performance between the prepared coatings and substrates indicated that pull-off strength values were more than 1.6 MPa, meaning a high adhesion strength. The phenylmethylsilicone oil leaching observation determined that the oil leaching efficiency increased with the increase in the structural unit’s molar content from MQ silicone in the copolymer, which was mainly owing to the decrease in compatibility between oil and the cured coating, as well as the decrease in mechanical properties. High oil leaching efficiency could make up for the decrease in the biofouling removal rate due to the enhancement of the elastic modulus. For CAMQ40, it had an excellent antifouling performance at 30 days of exposure time with more than 92% of biofouling removal rate, which was confirmed by biofilm adhesion assay.

“…Recently, self-healing coatings which consist of a shape-memory epoxy (SME) and microspheres containing self-healing agents are intensively researched in corrosion prevention. − The SME is a smart material that has the ability to recover from a temporary deformation to its original permanent shape because of entropically driven processes assisted by an external thermal stimulus. , Microspheres are purposely used as a carrier to control the release of self-healing agents contained inside. − Several reports demonstrated that microsphere carriers made from polycaprolactone (PCL) have dominant advantages such as high strength, slow degradation, high compatibility, high elasticity, and inexpensiveness. − In addition, cerium(III) nitrate (Ce(NO 3 ) 3 ) is a well-known corrosion inhibitor, especially for aluminum alloys . This is due to the fact that cerium(III) cations (Ce 3+ ) are capable of passivating any scratches or marks on the substrate by the formation of cerium hydroxide. − …”

“…The self-healing coating has an ability to recover from any light superficial damage or suppress any corrosion initiations of metal substrates. In turn, self-healing coatings reduce the degradation of coating materials, prolong service life of coating materials, and reduce the repair cost of coating materials in industries that encounter corrosion. ,− Even if this concept seems to be promising, the key achievement in smart coatings is the stability of carriers that contain self-healing agents, which depends on the preparation techniques. − Among those techniques, a double emulsion evaporation (DEE) technique is of interest because it can be used to encapsulate the corrosion inhibitors with high efficiency. − …”

The shape-memory epoxy (SME) mixed with 10 wt % polycaprolactone (PCL) microspheres containing 5% cerium(III) nitrate (Ce(NO 3 ) 3 ) (PCL5Ce) was coated on an aluminum plate 2024-T3 to investigate the self-healing property. The coating was scratched and heated at 80 °C for 30 min to activate the self-healing mechanism and compare with a nonscratched coating. Surface morphology was investigated by scanning electron microscopy. The scratch was completely healed by the PCL5Ce via a thermally assisted self-healing process. Based on electrochemical impedance spectroscopy, the postheated scratched coating had shown impedance values close to the nonscratched coating, which indicated that corrosion resistivity was restored. Ce(NO 3 ) 3 content at the scratched area was analyzed by focused ion beam–scanning electron microscopy. The scratch width was healed and filled with Ce(NO 3 ) 3 . Therefore, PCL5Ce is capable of being used as an enhancing additive for the self-healing performance in SME coating.
