Multilayer films, consisting of poly(2,5-dimethoxyaniline) (PDMA) and phosphotungstic acid (PTA) as alternative layers are assembled on a glassy carbon (GC) electrode to obtain (PDMA/PTA)(n) layer-by-layer (LBL) film, (where n = number of layers of PDMA/PTA) through electrochemical polymerization and chemical treatment with PTA. The film assembly, electrochemical property as well as the electroactivity of GC/(PDMA/PTA)(n) toward oxidation of ascorbic acid (AA) were investigated. The enhanced electrocatalytic activity of LBL (PDMA/PTA)(n) film towards AA was attributed to the existence of tungsten atoms in the interlayer of PDMA that augments the electron transfer processes.
