Abstract
- The results of investigations on corona charged thin mesogenic films consisting of solid mixtures of achiral liquid crystalline side-chain polymers and their monomers are presented. A pyroelectric modulation and a low frequency piezoelectric technique were used to confirm the polar properties of these compounds. The pyroelectric coefficient γ and the apparent longitudinal piezoelectric coefficient d33 were measured in the glassy state to be 3.2 nC/cm2K and 9 pC/N. The pyroelectric currents versus modulation frequency for various polar materials were studied for comparison.
