132 Construction and properties of novel thermally stable and chiral polymer based bionanocomposites containing modified nanoparticles such as ZnO and TiO2 under ultrasound irradiation Fatemeh Zeraatpisheh fzeraatpisheh@gmail com f zeraatpishe@ch iut ac ir January 06 2013 Department of Chemistry Isfahan University of Technology Isfahan 84156 83111 I R Iran Supervisor Prof Shadpour Mallakpour Email mallak@cc iut ac ir mallak777@yahoo com mallakpour84@alumni ufl edu Advisor Prof Hassan Hadadzade Department Graduate Coordinator Assos Prof H Tavakol Isfahan University of Technology 84156 83111 Isfahan Iran Isfahan University of Technology 84156 83111 Isfahan Iran Abstract In the first project of this investigation a new class of poly ester imide s derived from N N pyromellitoyl bis L tyrosine dimethyl ester as a diol and different diacid was prepared via polycondensation reaction using Vilsmeier adduct In the next part to improve the dispersion and obtain the homogeneous distribution of ZnO and TiO2 nanoparticles in polymer matrix the surface of nanoparticles was modified with silane coupling agents and was mixed with one of the prepared polymers which its biological properties were investigated Novel bionanocomposites were prepared by embedding of different nanoparticle contents into polymer matrix via ultrasonic method as a facial and inexpensive route The FE SEM and TEM results indicated that the particles were dispersed homogenously in nano scale in polymer matrix TGA confirmed that the thermal stability of the polymer was improved Then a new class of poly ester imide s via polycondensation reaction of N N 3 3 4 4 benzophenonetetracarboxylic 3 3 4 4 diimido bis L tyrosine methyl ester as a novel optically active diol and different diacid chlorides was prepared In the next part a new class of poly amide imide s containing 4 4 methylenebis 3 chloro 2 6 diethyl trimellitimidobenzene as a novel diacid was prepared Then novel nanocomposites were prepared using poly amide imide containing synthesized diacid and 4 4 methylenebis 3 chloro 2 6 diethylaniline as a commercial diamine by embedding of different silane coupling agent modified ZrO2 nanoparticle contents into polymer matrix Key word Optically active polymers Tyrosine amino acid Poly ester imide Poly amid imide Biodegradability Bionanocomposite
