  • Fabrication of polymer nanocomposites via ball milling

    Ball milling is based on the occurrence of collisions between the milling tools inside a batch reactor that contains materials in powder form , , , The collisions are a consequence of the reactor, or a part of it, moving , During each collision, a fraction of the powder is trapped between the colliding surfaces and subjected to mechanical load , , , as schematically shown in Fig 2a brief description regarding high energy ball mills Figure 1 A rock tumbler Ball mills The tumbler ball mill is a cylindrical container rotated about its axis in which balls impact upon the powder charge The balls may roll down the surface of the chamber in a series of parallelMechanical Milling: a Top Down Approach for theMechanical alloying (MA) is a powder metallurgy processing technique that involves repeated cold welding, fracturing, and rewelding of powder particles in a highenergy ball mill Due to the specific advantages offered by this technique, MA was used to synthesize a variety of advanced materials This article presents two specific examples of synthesis of nanocomposites containing a high volumeSynthesis of nanocomposites and amorphous alloys by
