Considerable work has gone into the development of synthetic systems that mimic biological approaches to provide adhesion in a wide range of environments. The catechol group is a workhorse functional group for this approach, capable of promoting adhesion through a number of transient interactions and oxidation states. We previously reported the development of a family of acrylate‐maleimide‐catechol (PAM) copolymers that varied the side chain to govern thermal properties and polarity. Here, we have used aluminium adherends to study the performance of the PAM series in an adhesive application, employing different deposition techniques to access ‘true’ and plasticized Tgs for the material. The polarity and effective Tg of the polymers had little correlation with the observed strength of adhesion, although some conclusions could be drawn about the series based on postmortem analysis and morphology characterization, where side chain assembly led to some periodic organization of the films. Adhesive strength to the adherends was sufficient to overcome the strength of the PAM, leading to a cohesive failure mode. Overall, the study revealed the importance of processing conditions and conditioning in the evaluation of novel polymer compositions. Published 2021.

带有邻苯二酚的马来酰亚胺-丙烯酸酯共聚物:探究附着力的平台

模仿生物方法以在广泛的环境中提供附着力的合成系统的开发已经进行了大量工作。邻苯二酚基团是该方法的主要功能基团,能够通过许多瞬时相互作用和氧化态促进粘附。我们之前曾报道过丙烯酸酯-马来酰亚胺-邻苯二酚(PAM)共聚物的开发,该共聚物可改变侧链来控制热性质和极性。在这里,我们已经使用铝粘附体来研究PAM系列在胶粘剂应用中的性能,采用了不同的沉积技术来获得材料的“真实”和增塑的T g。极性和有效T g尽管可以基于事后分析和形态学表征得出有关该系列的一些结论,其中侧链组装导致了薄膜的某些周期性组织,但这些聚合物与观察到的粘合强度几乎没有相关性。对被粘物的粘合强度足以克服PAM的强度,从而导致内聚破坏模式。总的来说,该研究表明在评估新型聚合物组合物时,加工条件和条件的重要性。2021年出版。本文是美国政府的著作,在美国属于公共领域。
