摘要：

This paper develops a novel and convenient approach to deposit poly(3,4-ethylenedioxythiophene)-reduced graphene oxide (PEDOT-rGO) hybrid film in aqueous solution through electrochemical process. The PEDOT-rGO film exhibited supperior charge transfer capability with charge transfer resistance of 1333 Omega.cm(-2) and standard transfer rate constant of 0.145 s(-1), which makes it a promising material for electrochemical sensing applications. The glassy carbon electrode modified with PEDOT-rGO showed good electrocatalytic performance towards acetaminophen with limit detection of 5.74 mu M, linear concentrations ranging from 10 to 60 mu M and sensitivity of 23.5 mu A.mu M-1.cm(-2). The use of acetaminophen sensor based on PEDOT-rGO in analysing Vietnamese traditional medicaments was demonstrated.
