Abstract

![CDATA[The silica nano-plates formed by exfoliation of the synthetic clay Lucentite in the poly(acrylic acid) aqueous solution has been examined using near edge X-ray adsorption fine structure (NEXAFS). Mg K - edge NEXAFS analysis shows that non surface (bulk) Mg ions were not chemically involved in the poly(acrylic acid)/clay intercalation, but were substantially involved in the exfoliation resulting in the silica nano-plates. During intercalation, O K - edge NEXAFS shows structural branches on the plate surfaces were formed. During exfoliation, these increased significantly. Si L 3,2 - edge NEXAFS shows this occurred by migration of SiO 4 groups within the exfoliated silica plates.]]
