Notes:
A new model is given to account for the pyroelectric effect in poly(vindylidene fluoride). Hopping of trapped charge carriers over the potential barrier and the existence of a trapped charge gradient are assumed. Exponential dependence of pyroelectric current gives an activation energy of the order of 0.65 eV and is explained on the basis of new theory. Pyroelectric current of 10-9 to 10-10 A has been found in solvent-cast PVDF films.
