Highly isospecific polymerization with Graphene oxide supported Ziegler-Natta Catalyst |
| 초록 |
Polymer/Graphene nanocomposites are interesting due to their mechanical and conductive properties. The preparation of graphene oxide GO)-reinforced polymer nanocomposites were challenging in obtaining well dispersed GO sheets in polymer matrix. Due to bearing abundant hydroxyl and carboxyl group on the surface of GO sheets, GO has received the most attetion and met with immense success in heterogeneous catalysis and nanocomposites. The mechanical and thermal properties of PP/graphene nanocomposites depend on istacticity of PP matrix and dispersity of GO. It's most important thing to applications of PP and that's composites. The objective this work is to prepare highly isospecific PP with GO-supported TiCl4 catalysts in the presence of various internal and external donors for preparation of PP/GO nanocomposites. The effect of polymerization conditions (kinds of internal donor and external donor, and [Al]/[Ti] molar ratio) on the activity and isotacticity are described. |
