Moscoso-Londoño,D. Muraca, L. M. Socolovsky, K. R. Pirota, M. I. Aranguren, M. Knobel and M.A.Mosiewicki, "Magnetism and Structure of Nanocomposites Made from Magnetiteand Vegetable Oil Based Polymeric Matrices" Materials Chemistry and Physics, 175, 81-91, (June 2016). Theaim of this work is to study the influence of the polymeric matrix compositionon particle aggregation, magnetic interparticle interactions and nanoparticlesurface effects, which affect the magnetic and structural properties ofdifferent ultra-diluted magnetite nanocomposites (MNCPs). Bio-based matriceswere selected as a possible response to the increasing demand for renewablematerials. To investigate the influence of different bio-based polymericmatrices on the magnetic behavior, three different bio-based polymers were usedto prepare MNCPs with 1 wt.% of magnetite nanoparticles (MNPs). One of them wasprepared using a tung oil (TO)/styrene (St) weight ratio of 70/30, a second onewas prepared by replacing the styrene with methylester (green comonomerobtained from tung oil, ME, 70TO/30ME) and a third one that incorporated agreen modifier, acrylated epoxidized soybean oil (AESO), using a tung oil/AESOweight ratio of 90/10. Structural features as nanoparticle aggregation state, nanoparticleand cluster sizes, and fractal dimension were studied and determined fromsmall-angle Xray Scattering (SAXS). The experimental SAXS data were analyzed bymeans of fractal aggregate model. Results indicate differences in nanoparticlearrangement depending of the containing matrix. The magnetic characterizationof these materials indicates that the matrix strongly affects the physical and chemicalproperties of the MNCPs. All samples display superparamagnetic behavior at roomtemperature, but the blocking temperature varies from 75 K (tung oil/styrenewith 1 wt.% MNPs) to 126 K (tung oil/AESO 1 wt.% MNPs). Furthermore, thetemperature dependence of the coercive field changes for all samples,suggesting a strong influence of the polymer properties on the magneticproperties of the MNCPs.
