14 Preparation and characterization of iron oxide nanoparticles and their application as nanopigments for formulation of a new anti corrosive paint anti corrosive alkyd primer based on alkyd resins Tahereh Alaedini t alaedini@ch iut ac ir Department of Chemistry Isfahan University of Technology Isfahan 84156 83111 IranDegree M Sc Language FarsiH Hadadzadeh Prof hadad@cc iut ac ir F Davar Assistant Prof davar@cc iut ac ir Abstract In this thesis the single phase Fe2O3 hematite nanoparticles have been successfully synthesized by asimple polymerizing complaxing sol gel method The morphology and particle size of the products wereinvestigated by field emission scanning electron microscopy FE SEM and X ray diffraction XRD Further the products have been characterized by fourier transform infrared FT IR spectroscopy Theestimated band gap from the UV Vis absorption spectra confirms the formation of nanoparticles TheFE SEM images show that the particle size of as prepared samples is from 20 to 40 nm The effect of theheat treatment on the hematite phase evolution was also investigated The vibrating sample magnetometermeasurement VSM and superconducting quantum interference device SQUID show that the sample T1possesses ferromagnetic property For the first time these nanoparticles have been modified by oleic acid OA In addition the nanopigments were used for prepartion of a new anti corrosive paint based on alkydresins Finally the anti corrosive properties of the paint have been investigated by linear sweep voltammetry LSV potentiostatic and electrochemical impedance spectroscopy EIS Key wordsIron oxide Sol gel Electrochemical impedance spectroscopy Anti corrosive paint Nanopigment Linear sweep voltammetry
