Modification by polyvinylpyrrolydone of the surface of fine-grained powders of iron and its compounds with platinum and silver

摘要

It is shown that there is a possibility for performing the modification of particles surface for highly dispersed iron powders and its compositions with platinum and silver by polyvinylpyrrolidone. Such properties of the powder particles surface as phisical adsorption and hydrophilicity enable to design composite materials for various applications, in particularly, for medicine (treatment for purulent-inflammatory deseases, wounds, ulcers etc.).
