通过线性偏振紫外线照射，然后加热，实现了光交联聚合物液晶膜中介晶基团的取向控制。取向方向平行于入射光的电矢量，介晶基团的倾斜角度可以通过一步倾斜LPUV照射来控制。光致双折射dn为0.07，介晶基团的有序参数为0.28。
Alignment control of mesogenic groups in a photocrosslinkable polymer liquid crystalline film was achieved by linearly polarized (LP) ultraviolet (UV) irradiation followed by heating. The alignment direction was parallel to the electric vector of the incident LPUV light and the tilt angle of the mesogenic groups could be controlled by a one-step slantwise LPUV irradiation. The photoinduced birefringence dn was 0.07 and the order parameter of the mesogenic group was 0.28.
