Electrical, Mechanical Properties and Morphology of SEBS-g-MAH/Graphene Nanocomposites

摘要

Poly (styrene-b-(ethylene-co-butylene)-b-styrene) (SEBS) is a kind of thermal plastic elastomer,and is widely used as materials in automobile,biomedical device,package,electrical equipment field,etc.However,the limited mechanical and electrical properties of SEBS could not be restricted in certain field.Due to the monolayer of perfectly two dimensional lattice of pure spa-bonded carbon atoms,graphene shows many extraordinary properties,such as electrical,optical,thermal,mechanical properties[1].It has been widely used as a nanofiller in the preparation of polymer nanocomposites to enhance the mechanical properties,electrical properties,gas blocking properties,thermal properties of the polymer matrix[2].However,pristine graphene is not compatible with organic polymers and does not form homogeneous composites.In addition,the van der Waals force between the interlayers lead to reunion of graphene,causing a great reduction of its performance[3].
