Novel polymer nanocomposites with iron oxide nanoparticles in a poly(1-vinyl-1,2,4-triazole) matrix are promising for the development of new biomedical materials of long-term effect. DOI: 10.1134/S1070427213090230 In recent years nanocomposite materials with metal nanoparticles, which have a set of valuable properties are widely used for the development of modern technology, effi cient catalysts, and pharmaceuticals. Twoand trivalent iron oxide Fe2O3, Fe3O4 possess superparamagnetic properties capable of forming a low-dimensional nanoparticles (8–10 nm) and applied in magnetic resonance imaging as a contrast agent [1]. Nanocomposites based on water-soluble polymers containing iron oxides may exert a long-term effect and are promising materials for use in medicine. Advances in this area is directly related to the problem of matrix stabilization of nanoparticles. Previously it was found that water-soluble non-toxic polymer poly(1-vinyl-1,2,4-triazole) is of high effeciency as a stabilizing matrix of silver and gold nanoparticles [2–5]. In the report the results are considered of the research in the synthesis and properties of new nanocomposite with iron oxide nanoparticles in the poly-1-vinyl-1,2,4triazole matrix.

Magnetic properties of perspective nanocomposite materials based on copolymers of 1-vinyl-1,2,4-triazole with acrylonitrile and the formation of zero-valence metallic magnetic nanoparticles were investigated by electron paramagnetic resonance (EPR). In the EPR spectra of the nanocomposites intensive narrow singlets of conducting electrons with g = 2.00 were observed. The shape and width of the signals for silver and copper particles of the nanocomposites depended on microwave power. The Curie law character of the temperature dependences of intensity, g-factor value, and width of silver and copper nanoparticles' signals were determined. Paramagnetic properties of the nanocomposites were found to remain constant over a long amount of time. X-ray diffraction (XRD), scanning electron microscope (SEM), teraohmmeter measurements, and atomic absorption analysis were also used to characterize these nanocomposites. The formation of the silver and copper nanoparticles from the rise of small clusters and their growth up to stabilization within the matrix under thermoreduction of initial complexes was monitored by EPR.
