title: One-Dimensional V(2) O(5) @Polyaniline Core/Shell Nanobelts Synthesized by an In situ Polymerization Method.
abstract: Uniform one-dimensional V(2) O(5) @polyaniline core/shell nanobelts have been fabricated by a simple in-situ polymerization method in the absence of any surfactant and additional initiator. The influences of pH and additional initiator on the morphology of the resulting products are investigated. The pH value is important for the formation of V(2) O(5) @polyaniline core/shell nanobelts, which preserve the original morphology of V(2) O(5) nanobelts. With a decrease in the pH value to 0 the original morphology of the V(2) O(5) nanobelts is destroyed. When ammonium peroxydisulfate is used, some separated polyaniline nanofibers are formed. The formation of the V(2) O(5) @polyaniline core/shell nanobelts can be related to the in-situ polymerization of aniline monomer by etching V(2) O(5) nanobelts. The electrochemical lithium intercalation/deintercalation of V(2) O(5) @polyaniline core/shell nanobelts is investigated by cyclic voltammograms.
