Preparation and characterization of reinforced poly(vinyl alcohol) films by a nanostructured, chiral, L-leucine based poly(amide-imide)/ZrO2 nanocomposite through a green method

- Thermal properties of modified ZrO2 were improved after incorporation into the PAI.
- Good dispersion of ZrO2 was obtained by using ultrasonic wave and surface modification.
- PAI-ZrO2 NC were used as filler in the PVA matrix for improving its properties.
- Morphology of PVA/PAI-ZrO2 films was explored by AFM, FE-SEM and TEM.
- The mechanical and thermal properties of PVA was increased after embedded PAI-ZrO2.
