GO is a promising material as a filler that had been paired with polymers to enhance the physical and mechanical properties of their composites. We are interested in the interphase of PMMA and graphene oxide, we based our understanding of a two state model with tightly and loosely bound polymer and compare the glass transition of the composites with bulk polymer. Different amounts of PMMA were adsorbed on graphene oxide. Glass transition behavior and heat capacities of polymer composites were examined by temperature modulated differential scanning calorimetric analysis (TMDSC). We find that the interactions among the GO sheets and PMMA are weaker compared to the interactions between silica and PMMA. Using the TMDSC thermograms recorded from GO-PMMA composites we will make an attempt to study the behavior of glass transition of PMMA on GO surface.
