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...
Tin phthalocyanine (SnPc)-doped polymer films were used to align ferroelectric liquid crystals (FLC). A stripe-shaped domain structure was obtained spontaneously in the initial alignment of the surface-stabilized cells. Atomic force microscopy (AFM) was introduced to investigate the aligning films. It was discovered that the modified aligning films show a polymer aggregate chain structure oriented...
