Films of PMMA–SiC–Cr2O3 nanocomposites are prepared to utilize in various electronics applications. The dielectric properties of PMMA–SiC–Cr2O3 nanocomposites are studied in frequency range from 100 Hz to 5 MHz. The results illustrate both the dielectric constant and the dielectric loss of PMMA–SiC–Cr2O3 nanocomposites reduced, while the conductivity rises with rising of frequency. Dielectric constant, dielectric loss, and electrical conductivity of PMMA are rising with rising in the SiC–Cr2O3 nanoparticles’ ratio. The results on dielectric properties demonstrate that the PMMA–SiC–Cr2O3 nanocomposites may be useful for electronics applications.
Key words: poly(methyl methacrylate), SiC–Cr2O3, nanocomposites, dielectric constant, conductivity.
