| Abstract: | 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 along the rubbing direction that may play an important role in the FLC alignment. The stability, memory capability and response time of the cell were improved and enhanced through the doping process. |
