The outstanding adhesive performance of mussel byssal threads has inspired materials scientists over the past few decades. Exploiting the amino‐catechol synergy, polymeric pressure‐sensitive adhesives (PSAs) have now been synthesized by copolymerizing traditional PSA monomers, butyl acrylate and acrylic acid, with mussel‐inspired lysine‐ and aromatic‐rich monomers. The consequences of decoupling amino and catechol moieties from each other were compared (that is, incorporated as separate monomers) against a monomer architecture in which the catechol and amine were coupled together in a fixed orientation in the monomer side chain. Adhesion assays were used to probe performance at the molecular, microscopic, and macroscopic levels by a combination of AFM‐assisted force spectroscopy, peel and static shear adhesion. Coupling of catechols and amines in the same monomer side chain produced optimal cooperative effects in improving the macroscopic adhesion performance.

高性能干/湿胶中邻苯二酚和胺的协同作用。

在过去的几十年中，贻贝的基底线的出色粘合性能启发了材料科学家。利用氨基邻苯二酚的协同作用，现在已经通过将传统的PSA单体，丙烯酸丁酯和丙烯酸与贻贝启发的富含赖氨酸和芳族的单体共聚来合成聚合物压敏胶粘剂（PSA）。比较了氨基和邻苯二酚部分彼此脱偶联的结果（即，作为单独的单体掺入）与单体结构的关系，在该结构中，邻苯二酚和胺在单体侧链中以固定的方向偶联在一起。结合力分析通过结合AFM辅助力谱，剥离和静态剪切结合力，在分子，微观和宏观水平上探测性能。
