The Dependence of the XRD Morphology of Some Bionanocomposites on the Silicate Treatment

open access: yesJournal of Nanomaterials, Volume 2008, Issue 1, 2008., 2008
The degree of intercalation of the polyvinyl alcohol‐starch blend with the layered silicate is increased if the silicates is untreated or intercalated with ammonium ions that contain small radicals. If untreated silicate like NaMMT is used, it is possible to obtain exfoliated‐intercalated nanocomposites. The materials based on PVOH, starch, and Nanocor
