摘要: ZnO nanospikes, due to their novel properties, are promising components in a wide range of nanoscale devices for future applications. Herein, current research activities focused on the synthesis, characterization and applications nanostructures encapsulated by hydrogen bonded liquid crystal matrix (HBLC e.g. azelaic acid heptyloxy benzoic acid) optical switching. We briefly describe smartest applied methodologies synthesis smooth dispersion within crystalline materials. In fact, HBLC doping was recently found significantly influence nucleation growth many functional nanocrystals (NCs), provide fundamental approach modify crystallographic phase, size, morphology, electronic configuration nanomaterials. All homologues present series show rich mesomorphism, exhibiting orthogonal tilted phases. A remarkable characteristics is then presented, organized into sections describing optical, electrical electro-optical phase transitions DC bi-stable switching properties. The other display parameters such as spontaneous polarization, rotational viscosity, response, capacitance, dielectric permittivity, loss spectra low frequency relaxation (Goldstone mode) also investigated these nanospike–HBLC composites, support observations described this article. Moreover, polarizing microscopy reveals various phases with different textural appearances, which proves nanomaterial. Most observed phenomena discussed terms new smectic ordering, named X*, sandwiched between traditional nematic convectional C* Dielectric relaxations pure doped LCs have been analyzed. feature article, we an overview most recent progresses (AC + 7BAO) doping-induced control efficient switching, well high performances nanomaterials, first time. These investigations developing versatile opto-electronic resolution devices.
