Polypropylene Filaments Modified with Manganese-Containing Nanoparticles

The influence of small amounts of low-density polyethylene, high-density polyethylene, and encapsulated manganese oxide nanoparticles on the mechanical properties and structure of polypropylene monofilaments was determined. It is shown that the introduction of small amounts of low-density polyethylene into polypropylene increases the degree of crystallinity of the polymer mixture and decreases the size of the crystallites. It is demonstrated that the strength and uniformity of the structure of monofilaments formed from a mixture of polyolefins do not deteriorate. A technology for creating complex filaments was developed based on polypropylene with a composite material based on low-density polyethylene and manganese-containing nanoparticles introduced into it as a filler. Comprehensive studies of the structure and properties of manganese-containing nanoparticles localized in the volume of low-density polyethylene were carried out. It was established that polypropylene filaments filled with manganese-containing nanocomposites based on low-density polyethylene have a set of improved characteristics: tensile strength increases, surface electrical resistance decreases, the ability to suppress the vital activity of gram-positive pathogenic bacteria and microscopic fungi appears.
