The Influence of ZnO nanoparticles in the epoxy resin on the complex permittivity and dissipation factor
Original language description
Epoxy resins are used as electro-insulating materials because they have great electro-insulation properties, adhesion, chemical resistance, and minimal shrinkage during curing. Epoxy nanocomposites have gained much interest in the area of nanotechnology, because of the ease of manufacture and the significant gain in properties. The influence of the various concentration of ZnO nanoparticles in epoxy resin Vukol 022 on the changes of the complex permittivity and dissipation factor has been measured at the temperature range from 20 °C to 120 °C. Frequency dependences of these parameters were measured within the frequency ranges from 1 mHz to 1 MHz by a capacitance method. The 0,5 wt.% nanoparticles caused a decrease of the real part of the complex relative permittivity. The higher concentration of nanoparticles for frequencies above 10 Hz had higher real relative permittivity as pure epoxy resin. At the study of the influence of temperature on dissipation factor, α-relaxation process and its shift to lower frequencies with ZnO fillers were observed.
