Abstract
Here the authors report a versatile and strong underwater adhesive that was inspired by the chemical features of mussel foot proteins. A random copolymer (poly(N-(3,4-dihydroxyphenethyl)methacrylamide-co-methacryloxyethyltrimethyl ammonium chloride-co-acrylamide) (PDMA)–Tf2N) was prepared that contained side-chain catechol groups and quaternary ammonium cations that were ion-paired with bis(trifluoromethane-sulfonyl)imide anion (Tf2N−). After dissolving PDMA–Tf2N and poly(acrylic acid) in dimethyl sulfoxide, a polyelectrolyte complex coacervate adhesive (P2) could be formed, which could be triggered through solvent exchange. P2 exhibited outstanding underwater shear strength to various substrate surfaces. After a critical curing time (ts = 10 min), the adhesion strength of P2 to glass increased sharply up to 187.298 kPa (ts = 40 min).
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
