NMR study of the slow dynamics and local structure in lyotropic micellar liquid crystals

摘要

The first experimental evidence of director fluctuations in a micellar lyotropic liquid crystal, stud- ied by ~1H spin-lattice relaxation rate, is reported. The system is constituted by the ternary mixture: potassium laurate/1-decanol/water. With the aim to test the slow dy- namics, the experiment has been performed over a broad range of Larmor frequencies (2×10~3-6.6×10~6 Hz), us- ing fast field-cycling NMR relaxometry.
