[Langmuir] Expanding the Scope of Surface Grafted Polymers Using Electroinitiated Polymerization

Updated: Aug 27, 2020

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.
