Sažetak
Magnetic polymer gels (ferrogels) are a new promising class of nanocomposite hydrogels, with potential application in soft actuators such as artificial muscles, in tissue engineering, drug delivery and hyperthermia applications. Although -irradiation method is highly suitable for generation of nanoparticles (NPs) in a solution as well as for the formation of three-dimensional polymer network, i.e. hydrogels, the radiolytic syntheses of iron oxide/polymer nanocomposite gels are rarely investigated, especially in the case of one-step synthetic approaches, such as the one used in this work. The radiolytic one-step synthesis resulted in the simultaneous crosslinking of the PEO polymer and the reduction of iron (III) salt (Figure 1). Electron microscopy, XRD, SQUID and Mössbauer measurements identified the particles as magnetite/maghemite and showed that they were < 5 nm in size, superparamagnetic and that there was a significant contribution of surface effects on the magnetic properties of the nanoparticles embedded in the hydrogel [1].
