Synthesis of Triazine-Based Polyimide Nanocomposites with Flower-Like ZnO by Microwave-Assisted Solvothermal Technique

Flower-like ZnO nanoparticles were synthesized by microwave-assisted solvothermal techniques in a simple system at 120 degrees C for 5h with the microwave synthesis method. Polyimide-ZnO nanocomposites were prepared by blending flower-like ZnO and the poly(amic acid). The prepared polyimide-ZnO nanocomposite films were characterized for their structure, morphology, and thermal behavior employing Fourier transform infrared spectroscopy (FTIR), scanning electron micrograph (SEM), X-ray diffraction (XRD), and thermal analysis (DTA/TGA/DSC) techniques. These studies showed the homogenous dispersion of ZnO in the polyimide matrix with an increase in the thermal steadiness of the composite films on ZnO loadings.
