Protective textile materials: obtaining and properties

Abstract

Protective textile materials with magnetic properties were obtained by in situ syn-thesis of magnetite nanoparticles using ferric chloride, ferrous sulfate and sodium hydroxide. The work is presented of the method of creating of the magnetic textile materials in the pro-cess of his modification by the synthesis of the nanoparticles in situ, taking into account the structure of textile material and nanotechnological processes. The morphology, crystal phase, magnetization properties of the treated textile materials were characterize by scan-ning electron microscopy (SEM), X-ray diffraction (XRD), vibrating sample magnetometry (VSM). It was found that magnetite nanoparticles with average crystal sizes of about 12.5 nm. The magnetite treated samples showed reasonable saturation magnetization values of about 7.5 emu g-1. The uniform distribution of the iron oxide nanoparticles on the surface of textile material was confirmed by SEM. Practical potential of treated materials is the ability to protective from shielding of electromagnetic radiation and in the presence of antimicrobial efficacy and is in the process of research.
