The Influence of Nanodispersed Silver/Alumina Addition on the Rheological Properties of Melts and Phase Transitions in Polypropylene/Copolyamide Blends
Journal Title: Фізика і хімія твердого тіла - Year 2014, Vol 15, Issue 4
Abstract
There is concentration influence of nanodispersed silver/alumina addition combined on appropriatenesses of polypropylene/copoliamide mixture melt flow studied. There are dependences of swelling and viscosity from Ag/Al2O3 concentration of extremal nature: the minimal viscosity and maximal elasticity are characteristic both for blend, containing 0.05% mass. of addition. It is shown, using DTA technique, that addition in low temperature range having positive influence on crystal structure forming of composite extrudates. It is founded, that silver in initial position distributed, mainly, in the cluster and nanoparticles (up to 20 nm) forms, and, mainly, in the extrudates of treble blends, as nanoparticle form. Mainly, the silver in polypropylene microfibers removed from treble extrudates, in cluster form founded. There is presence of silver in polypropylene microfibers, which is important for creation of bactericidal thin-fibrous filters.
