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 (t _s = 10 min), the adhesion strength of P2 to glass increased sharply up to 187.298 kPa (t _s = 40 min).

灵感来自贻贝:仿生聚电解质复合物凝聚胶通过水交换启动连接

在这里，作者报告了一种多功能和强大的水下粘合剂，其灵感来自贻贝足蛋白质的化学特性。制备了一种无规共聚物(聚(N-(3,4-二羟基苯基)甲基丙烯酰胺-共甲基丙烯氧氧乙基三甲基氯化铵-共丙烯酰胺)(PDMA) - Tf2N)，其侧链儿茶酚基团和季铵盐阳离子与双(三氟甲烷-磺酰)亚胺阴离子(Tf2N−)离子配对。PDMA-Tf2N与聚丙烯酸在二甲亚砜中溶解后，形成聚电解质络合物凝聚胶(P2)，通过溶剂交换触发。P2对各种基材表面均表现出优异的水下抗剪强度。经过临界固化时间(t s = 10 min)后，P2与玻璃的粘附强度急剧增加，达到187.298 kPa (t s = 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.
