preparation and properties of biodegradable pla/pbat/nanoclay nanocomposite

In this study, biodegradable polylactic acid/poly butylene adipate-co-terephthalate with modified  montmorillonites (cloisite 30b) , (closite 20a) were prepared using the melt blending method. we investigated the effect  of nanocomposites on the mechanical and rheological properties. the results revealed that mmt was preferable to localize on the interface of pla and pbat and esterification reaction took place between organic-modified mmt and pla/pbat. the extent of the intercalation was higher for nanocomposites based on modified clays (c30b) with chemical affinity with the polymer matrix.
