Abstract
A kind of newly synthesized polyimide (PI) LB films were fabricated to align ferroelectric liquid crystal (FLC). The topologies of PI LB films treated by different imidization processes were investigated by atomic force microscopy (AFM). It is found that the imidization temperature influences the crystalline structure of the LB films and high-temperature imidized LB films can provide the energy barrier for the realization of excellent bistability, while the ultra-thinness of LB films is helpful for the quick response of the FLC cell.
