62 Preparation and characterization of novel chiral nanostructured poly amide imide s derived from 3 5 diamino N thiazol 2 yl benzamide and various amino acids based diacids and preparation of zinc oxide chiral poly amide imide nanocomposites Hashem Ahmadizadegan hashem ahmadizadegan@gmail com 3 september 2012 Department of Chemistry Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language Farsi Supervisor Prof Shadpour Mallakpour E mail mallak@cc iut ac ir mallak777@yahoo com mallakpour84@alumni ufl edu Abstract We report here a green approach toward the synthesis of novel optically active poly amide imide s bearing thiazole moiety which condensed from the reaction of 3 5 diamino N thiazol 2 yl benzamide and diacids containing various amino acids in molten tetrabutylammonium bromide A novel diamine monomer was synthesized via reduction of 3 5 dinitro N thiazol 2 yl benzamide by iron oxide hydroxide catalyst in methanol This catalyst can be reducing the sulphur and azo containing aromatic nitro compounds rapidly to the corresponding amines in high yield by employing hydrazine hydrate as a hydrogen donor and we report novel optically active poly amide imide ZnO bionanocomposites PAI ZnO BNCs containing L valine moiety in the main chain were prepared via a simple and inexpensive ultrasonic irradiation process PAI ZnO BNCs containing 4 8 and 12 of nanoparticles were successfully fabricated through ultrasonic irradiation technique The obtained BNCs were characterized by Fourier transform infrared FT IR spectroscopy thermogravimetry analysis X ray powder diffraction UV Vis spectroscopy field emission scanning electron microscopy FE SEM and transmission electron microscopy TEM Thermogravimetric analysis data indicated an increase thermal stability of the BNC polymers in compared to the pure polymer From TEM image of PAI ZnO BNCs it can be found that the surface modified ZnO nanoparticles with less than 35 nm diametric size uniformly dispersed in the obtained PAI matrix Key word Amino acid Green chemistry Poly amide imide Chiral polymer
