Dielectric constant di water
WebFigures 2a, 2b and 2c show the varia- tion of the dielectric constant ' with frequency of temperatures between -50 and -10 °C for xerogels of PVA with different crosslinking degrees (4, 6 and 12 F/T cycles respectively). It is observed from the figures that the dielectric constant ' continuously decreases with increasing frequency.
