Abstract
In the present work, Graphene Oxide (GO) was modified by in-situ polymerization in the presence of methylmethacryalte and was used to improve the dispersion of GO nanoparticles as well as mechanical properties in polymethylmethacryalte (PMMA) matrix. Fourier Transform InfraRed (FT-IR) technique was used to confirm the successful modification of GO. PMMA nanocomposites were prepared by melting method and Thermal Gravimetric Analysis (TGA) and Field Emission Scanning Electron Microscopy (FESEM) techniques were applied in order to characterize the prepared nanocomposites. Also, the effect of GO percentage and processing parameters were studied by Taguchi Design of Experiment.  (GO content: 0, 2, and 4 wt%, injection pressure: 40, 60, and 80 MPa, holding pressure: 60, 80, and 100 MPa, and holding pressure time: 1, 2.5, and 4 s were mentioned as the variable parameters). To investigate the mechanical properties of nanocomposites tensile strength, hardness, and impact tests were carried out.
