Application of retardation-modulation polarimetry in studies of nanocomposite materials
2019
We demonstrate an application of retardation-modulation
polarimetryin studies of nanocomposite materials. Molecular ordering is explored on both nonchiral and chiral liquid crystals (LCs) in the bulk state and embedded into
parallel-arraysof cylindrical channels of alumina or silica membranes of different channel sizes (12-42 nm). Two arms
polarimetryserves for simultaneous measurements of the birefringence retardation and optical activity characterizing, respectively, orientational molecular ordering and chiral structuring inside nanochannels.
