Description
Summary:[Display omitted] •Poly(1-amino-9,10-anthraquinone) was synthesized in the micelle solution of SDS.•Polymer films with an extended active-suface obtained through the surface-assisted electro-ploymerization.•PAAQ/SDS films have the modified microscopic and macroscopic properties.•PAAQ/SDS/Pt modified electrode can be used as a sensor for cathecol. In this work, the poly(1-amino-9,10-anthraquinone) (PAAQ) films are synthesized electro-chemically by the direct anodic oxidation of 1-amino-9,10-anthraquinone (AAQ) on a platinum substrate in an ionic micelle solution containing the environmental friendly surfactant sodium dodecyl sulfate (SDS). The PAAQ–SDS films prepared are characterized by cyclic voltammetry (CV) and scanning electron microscopy (SEM), and a comparative study is carried out on the PAAQ films prepared under the identical conditions but in the absence of SDS. The results obtained show that the AAQ polymerization rate increases initially with an increase in the concentration of SDS, passed through a maximum around 0.4mM, and then decreased towards lower values, with a further increase in the SDS concentration. The PAAQ films deposited onto the electrode surface using the CV technique were adhesive and homogeneous. A distribution of the small particles and an extended surface area were observed in the SEM images for the porous PAAQ–SDS films. The preliminary results obtained show that the reliability and stability of the PAAQ–SDS modified electrode provide a good possibility for the electro-analytical determination of catechol.
