Bolometric Polymer Layers.
Abstract
The objective of this program was to synthesize polymeric materials of high pyroelectric efficiency and to prepare thin test films suitable for use in pyroelectric vidicons. Five atactic 4-substituted styrenes, were synthesized and evaluated, as were three isotactic 4-substituted styrenes. Their lack of pyroelectric effect was attributed to the helical structure of the substituted styrenes and the resultant lack of a net permanent dipole. Laser evaporation was found to be a very useful method of fabricating polymer thin films. Laser-evaporated poly(vinyl fluoride) exhibited a significant pyroelectric coefficient. A study of the basic mechanisms of pyroelectric polymer behavior was conducted and a model developed. Polarization processes and annealing behavior are also discussed. (Modified author abstract)
