“…Furthermore, the disappearance of the peaks of the nitro ( NO 2 ) group can be attributed to the conversion of NO 2 to the NO group after photoreaction, leading to the shift of the peak to approximately 400 eV (Fig. 2d) [29,31].…”

“…[ 153 ] The combination of a self-polymerisable and a photocleavable site in a single molecule allowed the use of ND to generate underwater adhesives with phototriggerable debonding ability. [ 154 ] A star PEG end-functionalized with ND groups formed a sticky gel by catechol-mediated oxidative coupling to form covalently crosslinks, or by association of the catechol groups with Fe(III) cations to form a metal crosslinked polymeric network (Figure 17 b). Upon UV irradiation, the terminal ND residue group underwent photolytic cleavage, resulting in a degradation of the hydrogel on selective regions (Figure 17 c).…”

Photoremovable protecting groups (PRPGs) are applied to organic surfaces, thin polymer films, and hydrogels to achieve light-based remote control of their (bio)chemical and physical properties. These can be localized (i.e. patterned), tunable by exposure dose, and generated on-demand. Using PRPGs with independent response to different wavelengths, multifunctional materials with a number of individually addressable functional states can be generated. Light-triggered polymerization, crosslinking, and degradation processes as well as release of attached molecules can be realized. Light-responsive surfaces and materials based on PRPGs open interesting possibilities for the next generation of instructive materials for cell culture and tissue regeneration.

“…In the early stages of the field, all the reported underwater self‐healing materials were based on water‐insensitive dynamic chemistries that can be categorized into two main groups: [ 4 ] i) boronic acid derivatives that contain boronic ester or boroxine bonds [ 5 ] and ii) nature‐inspired and hydrogen‐forming catechol groups. [ 6 ] However, they both have limitations. Boronic acid derivatives suffer from severe hydrolysis, and they are very unstable under water.…”

Integrating self-healing capabilities into soft electronic devices increases their durability and long-term reliability. Although some advances have been made, the use of self-healing electronics in wet and/or (under)water environments has proven to be quite challenging, and has not yet been fully realized. Herein, a new highly water insensitive self-healing elastomer with high stretchability and mechanical strength that can reach 1100% and ≈6.5 MPa, respectively, is reported. The elastomer exhibits a high (>80%) self-healing efficiency (after ≈ 24 h) in high humidity and/or different (under)water conditions without the assistance of an external physical and/or chemical triggers. Soft electronic devices made from this elastomer are shown to be highly robust and able to recover their electrical properties after damages in both ambient and aqueous conditions. Moreover, once operated in extreme wet or underwater conditions (e.g., salty sea water), the self-healing capability leads to the elimination of significant electrical leakage that would be caused by structural damages. This highly efficient self-healing elastomer can help extend the use of soft electronics outside of the laboratory and allow a wide variety of wet and submarine applications.
