“…For example, mussels can survive in extreme conditions. The reason is that byssus can form multiple interactions as hard and soft phases to enhance its durability. , Inspired by this natural mechanism, extensive strategies that combine strong and weak bonds have been developed to obtain tough and self-healing polymer elastomers capable of healing at room temperature without any external stimuli. Yu et al fabricated a self-healable silicone elastomer based on coordination interactions and ionic bonds . Unfortunately, the silicone elastomer showed moderate mechanical properties (tensile strength of 0.73 MPa and elongation at breaking of 548%) and healing efficiency (80%).…”

“…The literature describing the use of self-healing materials for space applications is relatively scarce today. Mainly extrinsic systems based on microcapsules were developed to prevent microcracks induced by UV irradiations. , Additionally, few studies investigated the use self-healing performance of ionomers after ballistic tests that could simulate space debris impacts. Recently, we developed self-healing PDMS dual networks based on the combination of permanent hydrosilylation and reversible Diels–Alder reactions and showed their enhanced aging properties under proton irradiations . However, the optical properties of these materials were not optimal for our quest for transparent self-healing coatings for solar panel applications in space.…”

“…18−20 networks based on the combination of permanent hydrosilylation and reversible Diels−Alder reactions and showed their enhanced aging properties under proton irradiations. 21 However, the optical properties of these materials were not optimal for our quest for transparent self-healing coatings for solar panel applications in space. In this study, we will focus on a synthetic approach that promotes the production of transparent self-healing PDMS.…”

“…External requires the encapsulation of ‘healing’ agents that, when damaged, fill the formed microfracture [ 5 , 6 ]. Internal is caused by the presence of different types of reversible–destructive bonds (disulfide bonds [ 7 ] and Diels–Alder reactions [ 8 ] for covalent–reversible interaction; hydrogen bonds [ 9 ], π-π stacking [ 10 ] and cation-π interaction [ 11 ], ionic [ 12 ], host–guest [ 13 ] and metal–ligand (M–L) interactions [ 14 ] for non-covalent reversible interactions).…”
