Abstract

The work presents a new type of orientation and method of liquid crystal alignment control inside a capillary. This method is a totally new approach which uses thermal activation to create an orienting polymer layer on the inner surface of a capillary. By using the polyamic acids SE-1211 that induce vertical anchoring, we obtained a splay orientation of the 6CHBT nematic liquid crystal in the capillary.
