Investigation of the elastic properties of poly (methyl methacrylate) reinforced with graphene nanoplatelets

The technique for synthesis of poly (methyl methacrylate) (PMMA) by atom transfer radical polymerization has been strengthened using graphene nanoplatelets (GNPs) to enhance the elastic properties polymer. In order improve practical, economical and mechanical performance, requirements effective implementation production control as a smart bulk polymer nanocomposite were determined cost-effective production. Three-dimensional inspection (using an ultrasound interrogation method whole volume under test) confirmed be free agglomeration bubbles. As result this elimination defects, enhancement in compressive strength 42.7% was achieved Rockwell hardness increased 19.9% through addition GNPs at 2 wt% mass. deformation failure have characterized nanocomposite. Elastic parameters testing identified that changes structural features following these uniquely connected enhancements (such Young's modulus, Poisson's ratio, shear microhardness) PMMA/GNPs
