preparation of polymer nanoparticles and doping by some schiff base compounds by using microemulsion systems

this study aims to prepare the nanoparticles of polyacrylic polymer by emulsion method using inorganic phase water and organic phase chloroforms to mixture these phases by surfactant cetyltri methyl ammonium bromide (ctabr) and doping the polymer with schiff base compounds to improve the properties of the polymer. the schiff base from azomethene derivatives [a1-a2] have been synthesized from the reaction of isatin with hydrazine once and with ethyl-4-aminobenzoate one more time, however the schiff base a3 has been synthesized from 3,4- dimethoxy benzylidene with hydrazine. the structures of polymer nanoparticles were identified by using x-ray diffractogram (xrd) to calculate crystallite sizes (d), and study the surface forms, morphology, and diameters of polymer nanoparticles by scanning electron microscope (sem) technology. in addition, the infrared spectroscopy (ft-ir) was utilized to characterize the functional groups of polyacrylic nanoparticle and schiff base syntheses. likewise, the hydrogen-1 nuclear magnetic resonance spectroscopic (1h-nmr) and carbon-13 nuclear magnetic resonance (13c-nmr) spectroscopic were used to determine schiff base syntheses.
