Realizing rapid and stable bonding under humid conditions has remained a challenge in adhesion science and wound dressing. In this study, polyacrylate-based underwater tape with water-enhanced adhesion and antimicrobial performance was designed and synthesized. Good underwater adhesion performance is achieved through the reasonable selection of comonomers, among which 4-hydroxybutyl acrylate (4-HBA) and isobornyl acrylate (IBOA) provide rich hydrogen bond interactions and a rigid side chain stable structure, respectively. The former effectively increases the interface strength between the tape and the substrate, while the latter ensures that the tape can maintain a good cohesion strength under water. Besides, povidone iodine (PVP-I) as a reinforcing filler and germicidal factor endows the tape with tunable mechanical properties and impressive antimicrobial abilities. This work provides a facile approach to prepare a wet adhesive for medical and industrial fields which can be used as wound dressing and underwater adhesive materials.

Marine oil exploration is important yet greatly increases the risk of oil leakage, which will result in severe environment pollution and economic losses. It is an urgent need to develop effective underoil adhesives. However, realizing underoil adhesion is even harder than those underwater, due to the stubborn attachment of a highly viscous oil layer on target surface.

Instant and strong adhesion to underwater adherends is a big challenge due to the continuous interference of water. Mussel foot protein-bioinspired catechol-based adhesives have garnered great interest in addressing this issue. Herein, a novel self-made catecholic compound with a long aliphatic chain was utilized to prepare thin (∼0.

Conventional adhesives experience reduced adhesion when exposed to aqueous environments. The development of underwater adhesives capable of forming strong and durable bonds across various wet substrates is crucial in biomedical and engineering domains. Nonetheless, limited emphasis placed on retaining high adhesion strengths in different saline environments, addressing challenges such as elevated osmotic pressure and spontaneous dimensional alterations.
