This book describes the preparation and characterization of nickel dispersed polyaniline matrix. Electronically conducting polyaniline was made magnetic in nature by incorporating magnetic metals into its matrix. In this connection, metallic Ni particles were successfully dispersed onto polyaniline matrix by a simple one step electrochemical method. Polyaniline/Ni film matrix as prepared was found to have excellent electroactivity. The result based on cyclic voltammogram suggests a better electrochemical stability of the polyaniline/Ni electrode relative to the bulk polyaniline film. An...
