dc.description.abstractTMAOH-dispersed nanoparticles of magnetite were first prepared through the reduction–precipitation of ferric chloride with Na2SO3 and NH4OH. The TMAOH-dispersed (Fe3O4) magnetic nanoparticles were then surface-coated with poly(L-co-D,L lactic acid-co-trimethylene carbonate) (PLDLA-co-TMC) to obtain the corresponding hybrid system (Fe3O4/TMAOH/PLDLA-co-TMC). Samples of so prepared material were analyzed by Fourier-transform infrared spectroscopy (FTIR), powder X-ray diffraction (XRD), magnetization measurements up to 2.5 T, and Mössbauer spectroscopy. Results indicate that this magnetic iron oxide soon after the synthesis is structurally close enough to a typically pure stoichiometric magnetite. FTIR data support clears evidences confirming the efficiency of the solvent displacement method to assure coating the TMAOH-dispersed (Fe3O4) magnetic nanoparticles with the terpolymer while preserves the main chemical structural characteristic of the nanosized magnetite.pt_BR
