Abstract
Bio-stereo nanocomposite polylactides are prepared by polymerization followed by stereocomplexation in scCO2/dichloromethane through in situ polymerization and master batch processes. The bio-stereo nanocomposite polylactides show intercalated-exfoliated and fully exfoliated nanoscale clay distribution in a perfect stereocomplex polylactide matrix. In situ polymerization proves better strategy to produce well-exfoliated silicate layers in the stereocomplex matrix compared to the MB route that increases the melting temperature by up to ≈64 °C. The thermal properties of these materials maintain both stereocomplex and nanocomposite features simultaneously. The results open a new and versatile way to develop polylactide-based materials. An advanced class of bio-hybrid material was developed and named bio-stereo nanocomposite polylactide. These novel polylactide-based materials consist of intercalated-exfoliated and fully exfoliated clay distributions in a crystalline stereocomplex polylactide. The bio-stereo nanocomposite polylactide possesses unique properties that contain both stereocomplex and nanocomposite features.
