Design, synthesis and application of hydrogen bonded smectic liquid crystal matrix encapsulated ZnO nanospikes

“…The surface stabilized smectic uniform helical texture and electro-optical switching with different temperature variations were observed using a polarizing optical microscope (model: OLYMPUS, CX31, 6J09934, Japan) with a U8031A signal generator. The spontaneous polarization (P s ) and the relaxation time were measured using a polarization reversal method eqn (1) and calculated using the following relation: 18,36,37…”

Switching of ferroelectric liquid crystal doped with cetyltrimethylammonium bromide-assisted CdS nanostructures

“…One-dimensional (1D) nanostructured materials doped with ferroelectric liquid crystals [23] are being intensively investigated because they impart remarkable improvement in the physical parameters of the host materials [24][25][26][27][28][29][30][31][32]. Novel functionalities are elicited depending upon the optical and electrical properties of the nanomaterials and the interaction of the nanomaterials with the orientational field of the liquid crystals.…”

Influence of ZnO nanostructures in liquid crystal interfaces for bistable switching applications

“…The resulting mixture was left to vigorous stir at 70°C for 3 hours to complete the whole reaction mechanism. We investigated that in our first set of experiment white precipitate was obtained, while next gray colored precipitate was (1) and calculated with the help of the following relation [24,[49][50]:…”
