Influence of cyclic freezing on the dynamics of silver nanoclusters on the surface of polypropylene and polyester fibers
A comparative analysis of the sorption of silver nanoparticles on the surface of polypropylene (monophile) and polyester (polyester) fibers after 10-fold cyclic freezing and defrosting, including sequential freezing to -37 ° C and raising the temperature to 0 ° C, has been performed. A significant (more than 8-fold) increase in the number of nanoparticles from 1 to 10 nm in size was revealed, accompanied by a decrease in the amount of silver nanoparticles with a diameter of 10 to 25 nm on the polypropylene surface. At the same time, no similar desorption of silver nanoparticles from the surface of polyester fibers was revealed, which indicates a stronger interaction of medium-sized nanoparticles with polyester fiber as compared to monophile.
