Preparation and Investigation the Properties of UHMWPE/Graphene Nanocomposites Via in Situ Polymerization Using Ziegler Natta Catalyst, Ph.D. Dissertation Sharif University of Technology ; Ramezani Saadat Abadi, Ahmad (Supervisor)
Abstract
The main object of the presented thesis is manufacturing ultra high molecular weight polyethylene(UHMWPE)/Graphene nanocomposites by insitu polymerization using Ziegler Natta catalysts. In this study, three types of Ziegler Natta Catalysts such as Magnesium ethoxide supported, single-supported and bi-supported have been studied. Experimental conditions are optimized (from point of productivity and molecular weight) by Design expert software with response surface methodology (Box-Behnken design). Effect of process parameters like temperature, pressure and [Al]/[Ti] molar ratio on productivity and Molecular weight are investigated. Also, the effect of hydrogen presence and type of cocatalyst...
