Abstract

Abstract Poly(1-amino-9,10-anthraquinone) (P1AAQ) nanowires have been directly electro-synthesized on a steel electrode, previously modified with a thin film of poly(P1AAQ-co-o-phenylenediamine), via a SiO₂ mesoporous template. Nanostructures obtainment was verified by electrochemical techniques and TEM. After template removal, it was corroborated that the nanowires, about 30 nm in diameter and 200 nm in length, were attached to the P1AAQ surface. The reproducibility of the method exhibited a standard deviation 3.357.10^-6 for P_{ox(0.8 V)} and 3.901.10^-6 for P_{red(0.003 V)} and, in addition, the response remains stable over ten successive voltammetric cycles. Characterization was conducted utilizing electrochemical techniques and visualized by SEM micrographs. Thus, to the pioneering methodology for obtaining polymeric nanowires utilizing just electrochemical techniques, this modification is now added in order to assure the adhesion of the polymeric nanostructures to the electrode surface; the feasibility of use of the device in the varied applications that these materials hold, is therefore envisaged.
