چکیده مقاله:

Graphene /poly(methylmethacrylate) nanocomposites were synthesized via one-pot in situ emulsion polymerization using graphene oxide as nanofiller then reduction of graphene oxide using hydrazine hydrate. The obtained nanocomposites were characterized by fourier transform infrared spectroscopy (FTIR), X-ray diffraction analysis (XRD), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC) and transmission electron microscopy (TEM). TEM images showed that poly(methylmethacrylate) microspheres linked to the edges of graphene nanosheets. The polymeric nanocomposites showed significant improvement in thermal stability and electrical conductivity and a considerable increase in glass-transition temperature
