Conditions for the open pores formation in medical textile materials for the treatment of wounds using iron oxide nanopowders

Abstract

One of the tasks of dressings in the process of wound treatment is to remove exudate. In the optimal case, this intensity is determined individually for each wound. Active medical textiles take advantage of the capillary effect that occurs in thin channels. For these purposes, medical materials are created from porous structures. To create back pressure in foamed medical materials, the pores must be in the form of channels, which is not realized with conventional technologies. The use of magnetic nanopowders based on iron oxide as an additive ensures the formation of channels of the required shape in the foamed materials. This effect makes it possible to increase the efficiency of foam structures when used as medical materials.
