Description
Summary:In field of nanotechnology, polymer based nanocomposites (NCs) with inorganic nanoparticles (NPs) have become a noticeable area of recent researches. In this work, citric acid (CA) was used as a biocompatible "modifier" for the alumina (α-Al2O3) NPs to prevent their agglomeration and create effective interaction with polymer matrix. In addition, chiral poly(amide-imide) (PAI) was synthesized by a direct polycondensation of N-trimellitylimido-L-phenylalanine dicarboxylic acid and 1,5-naphthalenediamine in ionic liquid as green solvent. Then modified (α-Al2O3-CA) NPs were incorporated into the obtained PAI through ultrasonic process for the preparation of PAI/α-Al2O3-CA NCs. Finally, the PAI/α-Al2O3-CA NCs were characterized by different methods.
