Abstract
Recently, we have developed a new family of ionic liquids that exhibit well-defined redox properties. Herein, we will report the surface modification of carbon materials by means of electrografting. Electrochemical processes based on oxidative or reductive grafting have been used for the attachment of organic molecules, such as redox active ionic liquids, onto various electrode surfaces providing new and special properties to the interfaces. The immobilization of redox active poly(ionic liquid) by surface-initiated atom transfer radical polymerization (SI-ATRP) process onto electrode surfaces has been investigated. The surface and electrochemical properties of these modified surfaces were investigated by combining different techniques (XPS, AFM, ellipsometry and contact angle). The nanostructured redox active poly(ionic liquid) exhibits high heterogeneous electron transfer rate about 150 s-1. We will show the use of redox active poly(ionic liquid) polymer brush as electrochemically reversible tunable surface wettability system and as electrochemical sensors.
