dc.description.abstractMagnetic and non-magnetic macroporous crosslinked copolymers of glycidyl methacrylate and trimethylolpropane trimethacrylate were prepared by suspension copolymerization and functionalized with diethylenetriamine. The samples were characterized by mercury porosimetry, scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM-EDS), Fourier transform infrared spectroscopy analysis (FTIR-ATR), thermogravimetric analysis (TGA), X-ray diffractometry (XRD), atomic force microscopy (AFM), transmission electron microscopy (TEM) and SQUID magnetometry. The FTIR-ATR analysis of synthesized magnetic nanocomposites confirmed the presence of magnetite and successful amino-functionalization. Non-functionalized and amino-functionalized nanocomposites exhibited superparamagnetic behavior at 300 K, with a saturation magnetization of 5.0 emu/g and 2.9 emu/g, respectively. TEM analysis of the magnetic nanocomposite has shown that magnetic nanoparticles were homogeneously dispersed in the polymer matrix. It was demonstrated that incorporation of magnetic nanoparticles enhanced the thermal stability of the magnetic nanocomposite in comparison to the initial non-magnetic macroporous copolymer.sr
dc.description.abstractU okviru ovog rada opisana je sinteza magnetičnih i nemagnetičnih makroporoznih umreženih kopolimera glicidil-metakrilata i trimetil-olpropan trimetakrilata suspenzionom kopolimerizacijom. Dobijeni uzorci su dodatno funkcionalizovani dietilentriaminom i okarakterisani živinom porozimetrijom, skenirajućom elektronskom mikroskopijom sa energo-disperzivnom spektrometrijom (SEM-EDS), infracrvenom spektroskopijom sa Furijeovom (Fourier) transformacijom (FTIR-ATR), termogravime-trijskom analizom (TGA), rentgenskom difrakcionom analizom (XRD), mikroskopijom atomskih sila (AFM), transmisionom elektronskom mikroskopijom (TEM) i SQUID-magnetometrijom. FTIR-ATR analizom sintetisanih magnetičnih nanokompozita potvrđeno je prisustvo magnetita i uspešna amino-funkcionalizacija. Nefunkcionalizovani i amino-funkci-onalizovani nanokompoziti pokazuju superparamagnetično ponašanje pri T = 300 K sa vrednostima magnetizacije zasićenja od 5 emu/g odnosno 2,9 emu/g. TEM analiza magnetičnog nanokompozita pokazala je da su nanočestice magnetita homogeno dispergovane u polimernoj matrici. TGA analiza je pokazala da inkorporacija nanočestica magnetita povećava termičku stabilnost magnetičnih nanokompozita u odnosu na početni nemagnetični makroporozni kopolimer.sr
