Anisotroptic liquid crystal (LC) networks prepared from reactive mesogens (RM) have numerous advantages in optoelectronic devices especially because of the excellent processability. To fabricate the robust LC thin films with excellent thermal, chemical and mechanical stabilities, the photo-polymerization of anisotropically pre-oriented RMs should be conducted on the optimized conditions. Since the final physical properties of anisotroptic LC networks depend on chemical functions and physical intermolecular interactions, the hierarchical superstructures of the programmed RMs with specific chemical functions should be controlled on the different length and time scales before polymerization. The presentation describes the fundamental characteristics and recent research interests of anisotropic LC networks, elastomers and gels fabricated using various programmed RMs.
Kwang-Un Jeong received his B.S. in Fine Chemical Engineering from Chonnam National University (Korea) in 1998 and M.S. in Materials Science and Engineering from Gwangju Institute of Science and Technology (Korea) in 2000. After receiving his Ph.D. in Polymer Science from The University of Akron (USA) in 2005, he worked as a post-doctoral researcher for two years in the field of polymer structure and morphology under supervision of Prof. Stephen Z. D. Cheng (The University of Akron) and Prof. Edwin L. Thomas (MIT). Since 2007, he has been a professor in Chonbuk National University of Korea.
