Research output: Contribution to journalArticlepeer-review


Paramagnetism in polyaniline can be generated during synthesis if cerium (IV) ammonium nitrate (CAN) is used as a polymerizing (oxidizing) agent. During the reaction, in situ formation of Ce 3+ ions are doped in the spherical polyaniline particles and show paramagnetic behavior throughout the experimental temperature range (400-1.9 K). The result indicated that the Ce 3+ ions covalently functionalized with the chain nitrogen of the polyaniline.
