Abstract
The observation of ferroelectric behavior in a Langmuir-Blodgett (LB) film of a liquid crystalline polymer is reported. It is established th at a 30-layer film exhibits spontaneous polarization and electro-optic switching. The magnitude of the polarization of the LB film is found to be similar to that of the bulk material. The polarization current i n the LB film follows the applied triangular wave field to higher freq uencies as compared to the same material in a surface stabilized (sand wich) cell.
