Abstract
The pyroelectric peroperties and the nature of the polarization of PAN have been investigated. The polarization that gives rise to the pyroelectric properties is caused by the “freezing in” of oriented dipole groups during cooling to room temperature in an electric field. The pyroelectric current is determined by the rotation of these dipoles around an equilibrium position as the temperature is changed. The maximum value of the pyroelectric coefficient, P, is equal to 3·9 × 10 −9 coulomb/cm 2·deg K. The production of electret films of large area and having a high value of pyroelectric coefficient makes it possible to put forward the question of using them as elements for the direct transformation of solar energy into electrical energy.
