Polyethylene/Clay Nanocomposites Prepared in an Internal Mixer: Effect of Processing Variable on Mechanical Properties
Polymer/clay nanocomposites have been explored extensively over the last two decades. Many studies report nanocomposite properties. However, studies on the effect of processing conditions are still limited. This study evaluates the effect of rotor type, rotor rotation (rpm) and mixing time on mechanical properties of polyethylene organoclay composites. Samples were fabricated using two different rotors; roller and Banbury, in an internal batch mixer at various mixing conditions. The analysis shows that the Banbury rotor improved mechanical properties more than the roller rotor. Shear and diffusion mechanism, as well as material degradation, were the controlling factors at different processing conditions.
