Effect of nanocomposites TiO2 addition on the dielectric properties of epoxy resin

الملخص EN

Sheets of Epoxy (EP) resin with addition of TiO2 of grain size (1.5 μm, and 50 nm) and weight percentage (1 %, 3 %, and 5 %) were prepared.

Discs of 20mm diameter and 3mm thickness were cut for dielectric measurements.

Dielectric properties (dielectric constant, dispassion factor and electrical conductivity) over the frequency range 102-106 Hz were measured.

Comparison was made between the effect of micro and nano particles of TiO2 on the dielectric properties of EP composites with different weight percentage.

Epoxy composites with micro sized particles of TiO2 were observed to have the better values of dielectric properties.
