摘要：

The observation of ferroelectric behavior in a Langmuir-Blodgett (LB) film of a liquid crystalline polymer is reported. It is established that 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 in the LB film follows the applied triangular wave field to higher frequencies as compared to the same material in a surface stabilized (sandwich) cell.
