Abstract

Coaxial cable-like conducting polyaniline (PANI)@titania nanofibers were synthesized and used as novel electrorheological materials. Under electric fields, the suspension of PANI@titania nanofibers showed notable yield stresses but significantly lower current densities compared to the suspension of pure PANI nanofibers.
