摘要

Abstract

In the present investigation

novel poly(amid-imide)/zinc oxide nanocomposites (PAI/ZnO NCs) containing benzoxazole and benzimidazole pendent groups with different amounts of modified zinc oxide nanoparticles (ZnO NPs) were successfully prepared

via

the

ex situ

method. Poly(amid-imide) (PAI) was prepared by direct polycondensation of 2-[3

5-bis(

-trimellitimidoyl)phenyl]benzoxazole (DCA) with 5-(2-benzimidazole)-1

3-phenylenediamine (DAMI) and provided the polymeric matrix with well-designed groups. The surface of ZnO NPs was functionalized with 3-aminopropyltriethoxysilane (APS) coupling agent to have a better dispersion and enhancing possible interactions of NPs with functional groups of polymer matrix. The amount of APS bonded to the ZnO surface was determined by thermogravimetric analysis. PAI/ZnO nanocomposites were characterized by Fourier transform infrared spectroscopy (FTIR)

X-ray diffraction (XRD)

and scanning electron microscopy (SEM). SEM analysis showed that the modified ZnO nanoparticles were homogeneously dispersed in polymer matrix. In addition

TGA data indicated an enhancement of thermal stability of the nanocomposite compared with the neat polymer.
