PROCESS FOR IMPROVING ADHERENCE OF POLYPYRROLE FILMS BY ANCHORS OF BIO-INSPIRED POLYMERS OF POLYDOPAMINE TYPE

摘要

The invention relates to a process for preparing polypyrrole films with increased adherence, intended to be applied to sensors, diodes, electrochromic devices. According to the invention, the process consists in creating polydopamine anchors on the surface of the Ti layer by chemical auto-polymerization of dopamine from aqueous solution and deposition of the polypyrrole layer by electro-chemical polymerization and the simultaneous film anchoring onto the formed polydopamine anchors, to result in polypyrrole films with an adherence value of 8.39 MPa.
