摘要：

The development of new nanocomposites comprising completely amorphous poly(lactic acid) (PLA), and montmorillonite with the main objective of obtaining new materials, was presented. The structure of the nanocomposites in the nanometer range has been established using WAXS patterns and TEM observations. The mixing of amorphous PLA with 4% organically modified montmorillonite OMMT and OMMB can lead to nanocomposites with stacked intercalated and partially exfoliated layers' morphologies shown by WAXS and TEM analysis. PLA/4OMMB nanocomposites exhibit a slightly higher thermal stability in comparison with neat PLA and PLA/4OMMT nanocomposites.
