Fabrication, characterization, and properties of novel poly(benzimidazole-amide)/functionalized ZnO nanocomposites (PBIA/APS-ZnO NCs) were investigated. At first, an aromatic PBA containing 3 imidazole units per repeat unit was synthesized by direct polycondensation of 1,3-bis(5-carboxylic acid-2-benzimidazole)benzene (BCAB) with 5-(2-benzimidazole)-1,3-phenylenediamine (DAMI) with good yield as a polymeric matrix. The periphery of zinc oxide nanoparticles (ZnO NPs) was modified with 3-aminopropyltriethoxysilane (APS) to have a better dispersion NPs and enhancing interactions between nanoparticles and PBIA matrix. Different percentages of functionalized NPs (0, 4, 8, and 12wt.%) were then embedded in PBA matrix through ultrasonic irradiation technique. Fourier transform infrared and thermo-gravimetric analysis (TGA) confirmed that APS was successfully attached on the ZnO NP surface. The obtained NCs were characterized by means of Fourier transform infrared, X-ray diffraction, scanning electron microscopy, and TGA. The TGA of the PBIA/APS-ZnO NCs showed the enhancement in the thermal stability in comparison with the neat PBIA and that this increase is higher when the NP content increases. Scanning electron microscopy analyses of NCs revealed that the dispersion of APS-ZnO NPs was uniformly done in the PBIA matrix.
But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 2343-89-7, you can contact me at any time and look forward to more communication. Product Details of 2343-89-7.
