To improve various properties of specialty films, precise control of molecular alignment is important. The existing practical process to align anisotropic molecules is rubbing, while there are some problems; a static generation, contamination of dust. For overcoming these problems, we have found a new principle to induce molecular alignment. When photopolymerization of a mixture of anisotropic monomer, cross-linker and photoinitiator is carried out through a moving photomask, unidirectionally aligned polymer films can be obtained due to monomer diffusion. However, the detailed mechanism remains unexplored. In this study, effects of surface treatment and properties of liquid -crystalline monomers on molecular alignment are discussed. Furthermore, the molecular alignment mechanism is considered.
