| Abstract: | The noncentrosymmetric liquid crystal LB films were prepared by the horizontal lifting method. Optical absorption spectra and morphological observation showed that aggregates of liquid crystal molecules were formed in the LB films. In order to observe the pyroeleotrio effect in the polar LB films, the Al LB film Al structure was fabricated. The static pyroeleotrio coefficient was of the order of 10-11.cm-21. The influence of the change of the LB film structure on the pyroeleotrio coefficient was discussed based on the experimental results. |
