                      Abstract:n  order  to  improve  the  stability  of  polyaniline(PANI)coating  during  long-
                 term  service  in  acidic  environment,PANI  was  first  modified  by  polyethylpyrrolidone(PVP)
                 through  one-step  electropolymerization  to  obtain  the  PANI-PVP  primer  coating,and


                 subsequently  a  macromolecular  proton  acid(phytic  acid,PA)doped  polypyrrole(PPY)top
                 coating was electrodeposited to construct the PANI-PVP/PPY composite coating system. The
                 differences  in  composition,structure,and  corrosion  resistance  between  the  PANI-PVP/PPY
                 and PANI-PVP coatings were investigated through FT-IR,SEM,and electrochemical tests.
                 The  results  showed  that  the  modification  by  PVP  significantly  improved  the  compactness,

                                                                                          t
                 reduced pore defects and the corrosion current density of PANI,meanwhile,he introduction of
                 PPY  coating  improved  the  electrical  conductivity  of  the  composite  coating  to  provide  a
