Functionalized Graphite Nanoplatelet by Nitroxide Radical PILs as Anode Materials for Li-ion Battery
We report organic radical functionalized graphite nanoplatelet (GNP) via a simple click reaction of the polymer propagated radical, polyvinylimidazolium functionalized with redox-active free radical TEMPO pendants groups. The as-obtained monomer was successfully polymerized by free radical polymerization at low temperature (40 ° C) by using 2,2’ - azobis(4-methoxy-2.4-dimethyl valeronitrile) as initiator. Finally, the CNO bond of the alkoxyamine pendant groups was thermally cleaved releasing the redox-active TEMPO nitroxide radicals. This simple and efficient strategy to synthesize graphite-functionalized PILs will provide new opportunities to fabricate many other polymer composite electrodes for desired electrochemical performance.
