As a kind of novel anticorrosion materials,polyaniline(PANI) exhibits great potentials in the field of steel anticorrosion. PANI hollow microspheres were fabricated by self-assembly method in poly(2-acrylamido-2-methylpropanesulfonic acid)(PAMPS) aqueous solution. After then,Ce~(3+)ions were loaded onto PANI to prepare Ce~(3+)doped PANI(PANI-Ce~(3+)) hollow microspheres. PANI-Ce~(3+)hollow microspheres were employed as functional additives and dispersed in epoxy resin(EP). Structure and morphology of PANI-C...
