Abstract
(EN)
The present invention relates to the technical field of nanomaterial synthesis, specifically the synthesis of polymer nanothreads electrosynthesised directly onto a solid surface, and a method for their production. More specifically, the invention includes a method for obtaining polymer nanowires or nanothreads joined directly to a substrate, the process consisting of the following steps: a) generating a polymer layer on an electrode; b) obtaining a mesoporous “mould” for guiding the formation of nanothreads, using a surfactant; c) removing the surfactant; d) generating growth of nanostructured conductive polymers (CPs); and e) removing the “mould”.
