Nanoporous Polymers Based on Liquid Crystals

چکیده
In the present review, we discuss recent advances in the field of nanoporous networks based on polymerisable liquid crystals. The field has matured in the last decade, yielding polymers having 1D, 2D, and 3D channels with pore sizes on the nanometer scale. Next to the current progress, some of the future challenges are presented, with the integration of nanoporous membranes in functional devices considered as the biggest challenge.

Microstructure and Optical Properties of Composites Consisting of Nanoporous Stretched Polypropylene doped with Liquid Crystals and Quantum Dots at a High Concentration
Unique properties of nanohybrid composites based on different types of porous polymer matrices doped with fluorescent nanoparticles (quantum dots, QDs) are determined by the combination of the mechanical properties of the host matrix (flexibility, chemical stability, etc.) and a high luminescence intensity and extreme stability of QDs. Here, we report on the preparation, optical and microstruct...
متن کاملEasily Accessible Thermotropic Hydrogen‐Bonded Columnar Discotic Liquid Crystals from Fatty Acid– Tris‐Benzoimidazolyl Benzene Complexes
We report the formation of easily accessible hydrogen-bonded columnar discotic liquid crystals (LCs) based on tris-benzoimidazolyl benzene (TBIB) and commercially available fatty acids. By increasing the length of the fatty acid, the temperature range of liquid crystallinity was tuned. Introducing double bonds in octadecanoic acid lowered the crystallization temperature and increased the temper...
متن کاملNanoporous polymeric transmission gratings for high-speed humidity sensing.
Nanoporous polymeric transmission gratings are demonstrated to be an excellent platform for high-speed optical humidity sensing. The grating structures were fabricated with a modified holographic, polymer-dispersed liquid crystal (H-PDLC) system. The sensing mechanism was based on changes in the relative transmission associated with the adsorption and desorption of water vapour by nanopores. Th...

Two novel semirigid smart polymers based on mesogen-jacketed liquid crystal polymers were successfully synthesized via free radical polymerization, which showed both characteristic liquid crystal properties of mesogen-jacketed liquid crystal polymers and remarkably reversible thermoresponsive phase transition behaviors.
متن کاملElectro-optic response and switchable Bragg diffraction for liquid crystals in colloid-templated materials.
We report optical switching studies on nematic liquid crystal incorporated into structures based on self-assembled colloids. We compare the electro-optic responses of liquid crystal imbibed into colloid-templated polymers, liquid crystal imbibed in the interstitial space of colloid crystals, and conventional polymer-dispersed liquid crystals. We characterize the Bragg diffraction of our templat...
