제목 Amphiphilic Layer-by-Layer Assembly Overcoming Solvent Polarity between Aqueous and Nonpolar Media and Its Applications to Hybrid Supercapacitor
초록 Amphiphilic Layer-by-Layer assembly is a versatile methodology that allows a facile incorporation of the functional components with completely different chemistry of hydrophilic/hydrophobic properties within nanocomposite films, and furthermore combine a number of the distinctive advantages of traditional electrostatic layer-by-layer (LbL) assembly in aqueous media and covalent LbL assembly in nonpolar media. Amphiphilic LbL assembly is based on the high affinitiy between sulfonic acid-fuctionalized materials in queous media and hydrophobic metal oxide (or metal) NPs in nonpolar solvent. This approach can be extended o the preparation of functional colloids (or carbon-based materials) materials allowing the reversible phase transfer between aqueous and nonpolar media and hybrid supercapacitor electrodes with high volumetric capacitance (280 F·cm-3 at 10 mV·s-1) using reuced graphene oxide with sulfonic acid moieties and well-defined OA-Fe3O4 NPs.
