Abstract
The use of lyotropic liquid crystals (LLC) as a template to form periodic nanostructures in polymer materials is a promising technology. In this study, cross- linked poly(ethylene glycol) diacrylate nanostructured materials were prepared by photopolymerization in LLC hexagonal phases. Polarized light microscopy and small- angle powder X-ray diffraction were used to understand the original LLC order retention on photopolymerization, and scanning electron microscope was used to investigate the morphology under different purifying solvents and drying conditions. A Quantachrome Autosorb 1 system was used to study the pore size distribution of samples. It was found that the LLC hexagonal structure was retained to a great extent after photopolymerization. The formation of nano- structures was affected by purifying solvent and drying condition. The nanostructure synthesized from LLC with favorably aligned nanopores will find increasing applica- tions in gas and water filtration, biology, and health science. V C 2010 Wiley Periodicals, Inc.
