  • Process and arrangement for the polarization of shaped objects made from polymers
    Patent number: 4381534
    Abstract: The invention relates to a method and an arrangement which are of importance in the polarization of shaped articles from polymers. The shaped articles from polymers, polarized by the method as per invention, are finding effective application in electroacoustic converters, piezoelectric switches and in proving electromagnetic radiation within a broad spectral zone.It is possible to obtain by the method as per invention and, respectively, the arrangement as per invention, above-average values for polarization as well as for the piezoelectrical and pyroelectrical coefficients. The arrangement as described, and respectively, the method as described are characterized by the use of charge-limiting polarization capacitors.
