The ability to rapidly modify the surface of materials is a powerful means of tailoring interfaces and interphases for a variety of applications. In this work, we demonstrate the extensive scope of an electrochemically mediated surface modification technique, able to install a range of surface grafted polymers of varying polarity and functionality. The irreversible reduction of aryldiazonium salts initiates polymer growth and provides a “priming layer” for the polymers to attach to, covalently anchoring them to the surface. We show the broad applicability of this technique through polymerization of 19 acrylate monomers, as well as a noncarbonyl bearing monomer species, styrene. Surface bound films were characterized using FT-IR, ellipsometry, and water contact angle.

使用电引发聚合扩大表面接枝聚合物的范围。

快速修改材料表面的能力是为各种应用定制界面和中间相的强大手段。在这项工作中，我们证明了电化学介导的表面改性技术的广泛范围，能够安装一系列极性和功能不同的表面接枝聚合物。芳基重氮盐的不可逆还原会引发聚合物的生长，并为聚合物提供“底涂层”，使其共价键合至表面。我们通过19种丙烯酸酯单体以及非羰基单体苯乙烯的聚合反应显示了该技术的广泛适用性。使用FT-IR，椭圆偏振法和水接触角对表面粘合的膜进行表征。
