Summary: | Polyamide-imide:ZnO nanocomposites (PAI:ZnO nanocomposites) were synthesized using ultrasonic cavitation technique. Meanwhile, ZnO NPs were synthesized using co-precipitation method and modified with diacid (DA) as coupling agent for enhancement in polymer–filler interaction. PAI was formed via microwave-assisted direct polycondensation of N-trimellitylimido-1-phenylglycine (DA) with 4,4′-diaminodiphenyl ether (diamine) by adding tetra-
n
-butylammonium bromide and triphenylphosphite as ionic liquid and condensing agent, respectively. The resulting polymer and modified ZnO NPs were employed to make PAI:ZnO nanocomposites and subjected to various characterizations [Fourier transform infrared spectroscopy, thermogravimetric analysis (TGA), X-ray powder diffraction, and field emission scanning electron microscopy (FESEM)]. The synthesized ZnO NPs were found to be spherical in shape with monodispersed form, which is evidenced from FESEM. TGA result reveals enhancement in thermal stability of nanocomposites with increase in amount of ZnO NPs loadings. Optical properties of nanocomposites show enhancement in-between ultraviolet region with amount of loadings. Moreover, the antibacterial studies have been carried out and found to be improved with increase in amount of ZnO NPs loading.
