Abstract

A novel approach to the surface modification of complex polypropylene fibers and films with metal-containing nanoparticles has been developed and experimentally validated. The process is implemented during melt extrusion of fibers and films. The proposed approach is based on the strong fixation of stabilized nanosized metal-containing particles on the surface of the material through the incorporation of a stable ultrathin polytetrafluoroethylene coating, formed using a previously developed technique. It has been shown that incorporating 0.001–0.2% of stabilized iron-, copper-, and silver-containing nanoparticles into the polytetrafluoroethylene coating increases its density without adversely affecting adhesion to the polypropylene substrate.
