Data storage using chiral nematic polymer mixtures...
Recording and storage of optical information using a cholesteric mixture of a menthyl-containing copolymer, a photosensitive chiral dopant, a mesogenic diacrylate, and a photoinitiating agent has been achieved. Several options are available for reversible and irreversible data storage based on photopolymerization of the diacrylate and untwisting of the copolymer helix (V. P. Shibaev et al., May 17; Adv. Funct. Mater. 2002
