摘要：

Sodium borohydride reduction of silver ions in aqueous dispersions of exfoliated graphite oxide (GO) resulted in the formation of remarkably monodisperse 100 Angstrom diameter oblate Ag particles that are effectively protected by 5 Angstrom thick GO sheets, Ag-GO. Ag-GO could be self-assembled onto poly(diallyldimethylammonium) chloride, PDDA, coated substrate; subsequent layer-by-layer self-assembly of Ag-GO and PDDA led to well-ordered ultrathin films of S-(PDDA/Ag-GO)(n).
