Abstract

In this article, at first, citric acid (CA) was used as a capping agent to control the size, dispersion and morphology of copper oxide (CuO) NPs (CuO-CA). The presence of CA on the surface of CuO NPs was confirmed by Fourier transform infrared spectroscopy and thermogravimetric analyses. Then biodegradable poly(amide-imide) (PAI) was synthesized through a polycondensation reaction of N-trimellitylimido-L-valine and 4,4′-methylenebis(3-chloro-2,6-diethylaniline) in green media. PAI/CuO-CA nanocomposites (PAI/CuO-CA NCs) containing different amounts of CuO-CA NPs in the PAI matrix were prepared using an ultrasonic-assisted technique. The PAI/CuO-CA NCs obtained were characterized using different methods.
