| Research Abstract |
We present a mean field theory to describe volume phase transitions of side-chain liquid crystalline gels, accompanied by isotropic-nematic-smectic A phase transitions. Three different uniaxial nematic phases and smectic A phases are defined by using orientational order parameters and translational order parameters. We find that the liquid crystalline gel discontinuously changes the volume at an isotropic-nematic, an isoropic-smectic A, and a nematic-smectic A phase transition. The conformation of backbone chains and mesogenic side groups are important to understand the swelling behaviors of liquid crystalline gels. We hope that these results encourage further experimental studies of the liquid crystalline gels.
