Ordering and density amorphous phase of polymer-matrix PTFE-composite materials with dispersed filler

Journal Title: Бюллетень науки и практики - Year 2018, Vol 4, Issue 6

Abstract

Discusses the impact of dispersed filler in the form of microcrystalline graphite (MG) on the formation of the supramolecular structure of the amorphous-crystalline polymeric materials the binary system of PTFE + MG. The theoretically calculated and experimental values of the composites densities are compared. The theoretical model of densities calculation takes into account the degree of crystallinity and the degree of the polymer-matrix (PM) ordering, as well as the deformation of the crystal cell in the amorphous phase. The degree of ordering and density of PM PTFE-composites amorphous phase behave in a complex manner with increasing content of dispersed filler and in a different way than with fibrous filler in the form of carbon fiber (CF). Studies of dual systems of PTFE + MG and PTFE + CF have shown that the ordering presence the amorphous phase can be considered one of the formation factors of the composite materials supramolecular structure based on amorphous-crystalline polymers.
