Design and Synthesis of Inorganic/Organic Hybrid Microstructures
Abstract
Vanadium oxide/polypyrrole (V2O5/PPy) hybrid aerogels were prepared using three different strategies. These approaches were focused on either sequential or consecutive polymerization of the inorganic and organic networks. The hybrid microstructure differed greatly depending on which synthesis approach was used. When the inorganic and organic precursors were allowed to polymerize simultaneously, the resulting gels exhibited a nanometer scaled microstructure with a homogeneous distribution of the PPy and the V2O5. Through this route, a suitable microstructure and composition for a lithium secondary battery cathode were obtained. For the full benefit of the PPy phase to be achieved, a suitable doping procedure is still required to oxidize the PPy into its high conductivity state while preserving the inorganic structure.
