Abstract

P(AN-co-VAc)/Fe2O3 core-shell nanocapsules were synthesized by miniemulsion polymerization and P(AN-co-VAc)/Fe2O3@PEDOT core-shell structure was constituted by oxidative polymerization. Homogeneous nanofibers were obtained from the core-shell nanocapsules. Characterizations were performed by XRD, GPC, UV-vis, and FTIR-ATR. SEM, AFM, and TEM. Molecular weight and Tg of the nanocapsules were effected by the increase in -Fe2O3 NPs. Nanofiber resistance (Rnfb) drastically decreased from 2700 to 110k.cm(2) by the inclusion of -Fe2O3 NPs into the nanocapsules 8.3k.cm(2) obtained after coating with PEDOT. The electrochemical Impedance results were fitted to models of [R (Q(R (CR)))] and [R (Q(R (QR)))], respectively.
