Summary: Wet adhesion technology has potential applications in various fields, especially in the biomedical field. Mimicking the adhesion principles of aquatic organisms can address the wet adhesion issue and design artificial adhesive materials. The barnacle cement secreted by crustacean barnacles has attracted research interest as a novel model for designing biomimetic adhesive materials. However, there is a lack of systematic reviews summarizing the design strategies and research advances of barnacle cement-inspired adhesive materials.

Summary: In this study, a long chain polymer (PDDA) with hydrophobic backbone and hydrophilic group was synthesized using small molecule polyethylene glycol diacrylate (PEGDA-200) and dopamine (DA) as raw materials through the Michael addition reaction. By utilizing hydrogen bond interaction and solvent exchange, a viscous aggregate (PDDA-SiW) was successfully formed, exhibiting strong underwater adhesion to various substrates and high adhesion to fresh pigskins. Additionally, PDDA-SiW showed low hemolysis and cytotoxicity, strong antibacterial properties, making it an excellent material for underwater adhesion and wound hemostasis.

Summary: A chemically functionalized PSA (f-PSA) with enhanced and phototunable underwater adhesion has been developed by incorporating an underwater adhesion enhancer (mussel-inspired catechol) and a photo-responsive functionality (anthracene) into a standard acrylic PSA matrix. This synergistic coupling secures sufficient interfacial molecular interactions and leads to enhanced underwater adhesion, while the efficient dimerization of anthracene via light-triggered cycloaddition facilitates the viscoelastic property of f-PSA, rendering it phototunable. The f-PSA is envisioned to open up more opportunities for applications such as underwater manipulation, transfer printing, and medical adhesives.

Summary: This study developed a semitransparent wood-based gel patch that can achieve instant and robust adhesion to various substrates both in air and underwater. The gel, synthesized by in-situ polymerization in the absence of chemical cross-linkers, showed superior adhesion to various substrates such as plastic, metal, PTFE, glass, and wood. The presence of C-F bond endowed the gel with low surface energy, resulting in outstanding underwater adhesion. The tensile stress of the gel reached 6.10-9.34 MPa, which was significantly higher than that of pure gels without wood incorporation. The maximum adhesion strength of the gel was approximately 350 kPa in air and 345 kPa underwater. This research demonstrates the promising application of the gel in emergency repair engineering of broken pipelines both in air and underwater.
