Abstract
The dielectric properties of composite materials prepared by embedding P(VDF60/Tr40) and P(VDF88/Te12) polar copolymers in porous glass matrices with a mean flow-through pore diameter of around 320 nm were investigated in the temperature range 200–450 K. Strong dielectric relaxation, the characteristic time of which conformed to the Williams-Landel-Ferry law, was observed in the vicinity of glass transition point Tg of an amorphous fraction of polymer inclusions. An increase (≈10 K) in the Tg temperature of the amorphous fraction of incorporated polymeric materials was detected.
