11 August 1998 Pyroelectric properties in polar hemicyanine Langmuir-Blodgett multilayer films

The Langmuir-Blodgett (LB) films of hemocyanin dyes were prepared by LB technique. The films show pyroelectric effect. The pyroelectric coefficient measured by the method of integrated charges is 12 (mu) C m-2 K-1 at room temperature. The relationship between the orientation of DAEP in the films and temperature was studied by polarized FTIR spectroscopy and second-harmonic generation. The physical mechanism of pyroelectricity in the films was also discussed.
