In this communication, a method for installing electrically conductive chemical groups onto the surface of cellulosic material is described. In particular, the method finds use of the established affinity of carboxymethyl cellulose (CMC) onto native cellulosic fibres to alter the properties of the cellulosic substrate. Over the recent years, robust, quick, and quantitative chemical reactions have been developed under the context of click chemistry, where the copper(I)-catalyzed azide-alkyne cycloaddition has been widely studied. CMC, modified with an azide functionality, is irreversibly adsorbed on the cellulosic substrate and a click reaction with the alkyne-functionalized pyrrole takes place subsequently. Produced template undergoes FeCl3-catalyzed polymerization yielding electrically conductive cellulose material. XPS, AFM, FTIR, four electrode probe method and SEM were used to characterize the modified cellulosic substrate. Main results and possible applications for such systems will be discussed.
