Abstract Nanocomposites of modified poly (methyl methacrylate) (C-PMMA) reinforced with zirconium dioxide (ZrO2) and cerium dioxide (CeO2) nanoparticles were prepared through in situ polymerization. Their dielectric and radiation shielding properties were also evaluated. We used p-phenylenediamine (p-PDA) to modify the PMMA matrix to make it more rigid and stable at high temperatures. Ceramic nanoparticles were incorporated into the composite at various loadings ranging from 5 to 40 wt%.

Metal oxide nanoparticles have been extensively studied recently as additives to improve the dielectric, optical, and electrical properties of polymer-based composites [Citation1–5]. However, many of them still have serious problems, such as the inhomogeneous dispersion of nanoparticles, insufficient correlation between particles, and the low performance enhancements of conductivity and permittivity [Citation6,Citation7].
