Abstract: Polyacrylonitrile coating was formed on aluminium cathode by in-situ electrochem-ical polymerization(ECP) at constant potential.The influences of supporting electrolytes,cell potential and monomer concentration on the performance and morphology of the coatingshave been studied.The coatings in 10~15 pm thickness could be obtained at polymerizationpotential of 7.0 V for 3 h in 1~5 mol/L AN solution of aqueous DMF containing 0.05mol/L AlCl3 as supporting electrolyte.The morphology and structure of the coatings havebeen examined by SEM and FTIR.The mechanism of ECP has been discussed briefly.

Key words: acrylonitrile, aluminium cathode, in-situ electrochemical polymerization
