Poly(N-acetylaniline)/poly(4-styrenesulfonic acid-co-maleic acid) (PNAANI/PSSMA) composite film was prepared by cyclic voltammetry (CV); and was characterized by FTIR and X-ray photoelectron spectrum (XPS). The electroactivity of the composite film was high in neutral and basic solutions; and it had been used for amperometric determination of ascorbic acid (AA). Compared with pure PNAANI film; the catalytic activity of the composite film was much better. AA was detected amperometrically in sodium citrate buffer at a potential of 0.3 V (versus SCE). The response current was proportional to the concentration of ascorbic acid in the range of 4.7 × 10-6 to 5.0 × 10-5 M and 5.0 × 10-5 to 2.5 × 10-3 M; respectively; with the detection limit of 1.9 × 10 -6 mol L-1 at a signal to noise ratio 3. In addition; the stability and reusability of the composite film were performed well; and it was satisfying to be used for determination of AA in real fruit juice samples. © 2008 Wiley Periodicals; Inc;
