Novel bionanocomposites of poly(vinyl alcohol) and modified chiral layered double hydroxides: Synthesis, properties and a morphological study

- N,N′-(pyromellitoyl)-bis-l-phenylalanine diacid was used for modification of LDH.
- PVA/LDH chiral nanocomposites were synthesized by ultrasound-assisted technique.
- Nanocomposite films were prepared by solution-intercalation technique.
- TEM and FE-SEM show that modified chiral LDH was uniformly dispersed in PVA matrix.
- The thermal properties of the organic/inorganic hybrids were improved.
