A novel carbon nanohybrid Pickering stabilizer was synthesized via a hydrothermal reaction of 2-ethyl-4-methylimidazole (EMI), graphene oxide (GO), and carbon nanotubes (CNTs). The EMI/GO/CNTs encapsulated poly(methyl methacrylate) (PMMA) microspheres were achieved via suspension polymerization after the formation of stable oil-in-water (o/w) Pickering emulsion using the as-prepared EMI/GO/CNTs stabilizer, which were used to elaborate PMMA-based nanocomposites through compression molding technique. Infra-red (IR) spectra and contact angle (CA) measurements showed that EMI/GO/CNTs nanohybrids was amphiphilic in nature. Mechanical tests and scanning electron microscope observation were performed to characterize the properties and microstructure of the resulting nanocomposites. PMMA nanocomposites containing networking EMI/GO/CNTs nanohybrids exhibited the maximum flexural strength of 73.1 MPa and compressive strength of 218.4 MPa at a GO-to-CNTs mass ratio of 6:1, respectively. The influences of the amount of EMI/GO/CNTs stabilizer and the ratio of GO to CNTs on the structure and properties of PMMA nanocomposites were discussed. POLYM. ENG. SCI., 58:1975-1980, 2018.
