Investigating the nanostructure and thermal properties of chiral poly(amide-imide)/Al2O3 compatibilized with 3-aminopropyltriethoxysilane

- Chiral polymer with different functional groups was prepared in green route.
- The surface of Al2O3-NPs was treated by KH550 as a silane coupling agent.
- NCs of poly(amide-imide) and Al2O3 were synthesized by ultrasonic irradiation.
- TEM results show good dispersion of Al2O3-NPs in the poly(amide-imide) matrix.
- The thermal and mechanical properties of the hybrid materials were improved.
