33 g of HDPE pellets were initially placed into the mixer chamber and then mixed at a rotor speed of 100 rpm for 5 minutes and a mixer temperature of 150 °C. During this time, the conductivity of the polymer and the mixer torque were determined and shown in a rheogram (Graphs 1, 2, and 3). Once the polymer became molten, 4 g of carbon black ...

There has been an increase in interest in developing functional polymer composites based on green chemistry principles. The purpose of this study was to investigate the preparation of functional epoxy/carbon nanotube nanocomposites using ball milling methods. In contrast to mechanical mixing, ball milling promoted good dispersion of CNTs within the epoxy matrix, thereby improving their ...

This study presents an approach for targeted comminution of component mixtures within a wetoperated stirred media mill. In the first step, a general understanding of the interactions between individual components on the grinding result with mixtures could be gained with basic experiments and following our former research work. In particular, a protective effect of the coarser particles on the ...
