Synthesis and Characterization of Novel Optically Active NanostructuredPoly amide imide s Containing Natural Amino Acids UsingTetrabutylammonium Bromide as an Ionic Liquid and Preparation ofPoly amide imide ZnO Nanocomposites Mohammad Iderli mohammadshimi82@yahoo com 17 December 2011 Department of Chemistry Isfahan University of Technology Isfahan 84156 83111 IranDegree M Sc Language FarsiSupervisor Prof Shadpour Mallakpour E mail mallak@cc iut ac ir mallak777@yahoo com mallakpour84@alumni ufl edu Abstract In this investigation the synthesis and characterization of novel chiral and nanostructured poly amide imide s PAIs have been reported Chiral diacids monomers were prepared from the reaction of pyromelliticdianhydride and different natural amino acids such as L valine L phenylealanine L alanine and L isoleucine Then direct polycondensation reaction of these optically active diacids with 4 43 methylenebis 3 chloro 2 6 diethylaniline was performed using molten tetrabutylammonium bromide as a green ionicmedium in the presence of triphenyl phosphite as an activating reagent PAIs were obtained in good yieldsand moderate inherent viscosity in the range of 0 43 0 49 dL g The obtained polymers were characterized bymeans of speci6c rotation experiments 1H NMR FT IR X ray diffraction XRD field emission scanningelectron microscopy FE SEM thermogravimetric analysis TGA and elemental analyses techniques Theresults from FE ESM and XRD showed that the obtained PAIs have nanostructure with particle size in arange of 47 130 nm before sonication and 49 74 nm after sonication process and amorphous morphology TGA of the PAIs showed that the obtained polymers have good thermal stability In the second project anovel chiral PAI based bionanocomposites BNC s have been successfully prepared via ultrasonic irradiationmethod using zinc oxide ZnO nanoparticles functionalized by aminopropyltriethoxysilane as a couplingagent to decrease aggregation of nanoparticles in polymer matrix The resulting BNCs were characterized byseveral techniques including FT IR XRD and TGA Also their morphology was investigated by FE SEMand transmission electron microscopy TEM analysis TEM and FE SEM images revealed that ZnOnanoparticles were good dispersed in nanosize in PAI matrix with particles size between 15 25 nm TGAdata showed an improvement of thermal stability of new BNCs in comparing with the pure PAI In the endproject biological and biodegradability properties of synthetic polymers and monomers were investigated Invitro fungal colonization and weight loss of the synthetic polymers showed that PAIs are probablybiologically active and biodegradable under natural environment Keyword Nanostructured polymers Optically active poly amide imide s Ionic liquid ZnO nanoparticle Bionanocomposite Coupling agent Biodegradable
