Reverse mode polymer stabilized liquid crystal (RPSLC) – have garnered significant attention due to their unique properties and promising applications in a variety of fields. However, high operating voltage and low contrast ratio are two potential challenges associated with using RPSLC in smart window. Herein, we have introduced azobenzene monomer with acrylic terminal, which serves as both a polymerizable monomer and dopant to improve the electro-optical properties of RPSLC films. We found that the polymer morphologies and electro-optical (EO) can be artificially manipulated by varying the contents of liquid crystal and azobenzene. Particularly, great improvement in EO properties were realized by doping 0.3 wt % azobenzene monomer, the threshold voltage and contrast ratio were 13.9 V and 202.9, respectively. This work opens a new avenue to regulate the microstructure and optimize the EO properties of RPSLC films.
