Polydopamine/cobalt hexacyanoferrate (PDA-CoHCF) composite films on a glassy carbon electrode (GCE) have been electropolymerized by using cyclic voltammetry. The composite films were electrochemically activated in a potassium hydroxide solution and were characterized by scanning electron microscope (SEM) measurements. The electrochemical activation could cause some changes of composite membrane interface structure and improve the electrochemical performance of the corresponding modified electrode in a phosphate buffer solution containing dopamine. The PDA-CoHCF film modified glassy carbon electrode could response dopamine sensitively in cyclic voltammetry measurements for electrochemical oxidation and reduction. The linear response slope and regression coefficient is 1.546 μA/μM and 0.985, respectively, in the concentration range from 2.0 μM to 10 μM dopamine.
