STRUCTURE AND PROPERTTIES OF BALL MILLED UTRAHIGH-MOLECULAR WEIGHT POLYETHYLENE - CLAY COMPOSITE

摘要

In this work the composite material based on polymer matrix filled with clay is studied. The preparation of powder composition consists of mechanical activation of substances and further common ball milling of polymer and clay in a high-energy planetary ball mill. The process is divided into two stages;;the first stage involves crushing of clay to obtain a nanosized powder, and in the second stage preparation of powdered nanocomposite is carried out. New clay-polymer composite shows considerable increase in modulus of elasticity and a decrease in coefficient of friction.
