Abstract

In this article two polymer/nanocomposite films with 5 and 10 % silicate particles based on Poly(amide-imide) (PAI) from N-trimellitylimido-L-phenyl alanine were prepared via solution intercalation method through blending of organoclay with the PAI solution. Poly(amide-imide) was synthesized by the direct polycondensation reaction of N-trimellitylimido-Lphenyl alanine with 4,4’-diamino diphenyl ether in the presence of triphenyl phosphite (TPP), CaCl2 and pyridine (Py). Morphology and structure of the resulting PAI-nanocomposite films were characterized by FTIR spectroscopy, X-ray diffraction and scanning electron microscopy (SEM). The effect of clay dispersion and the interaction between clay and polymeric chains on the properties of nanocomposites films were investigated by using Uv-vis spectroscopy, thermogravimetric analysis (TGA) and water uptake measurements.
