Pseudopeptidic polymers for modulating electro-optic switching, dielectric and electrical properties of liquid crystal

Synergetic Enhancement of Seebeck Coefficients and Electrical Conductivity in Flexible Liquid Crystal Composites

“…28 Generally, the pristine LC sample contains mobile ions due to the involved synthesis process. 29 These mobile ions of LC contribute to the Soret effect as the thermal gradient is provided to the LC-doped sample. Therefore, the LC-doped composite film exhibits an enhanced Seebeck coefficient value compared to the reference composite film.…”

“…The higher concentration of LC has decreased the electrical conductivity value because of the increasing contribution of intrinsic poor conductivity of 5CB and the energy filtering effect introduced in the composite due to formed multiple interfaces in the sample (Figure 2b,e). 29 A high interface resistance, substantial electron scattering, and carrier filtering might result from the growing LC concentration because a pure LC is a dielectric material and could disrupt the continuous interpenetrating network structure of the pristine SWCNTs. 7 As previously described in the literature for conjugated polymer/CNT or graphene composites, the energy filtering effect reduces the electrical conductivity value.…”

Liquid crystal droplet design by using pseudopeptidic bottlebrush polymer additives

“…44,45 To the best of our knowledge, polymer molecular brushes are never used for PDLCs fabrication. 27,46,47 We have developed the PDLCs for sensing application in the present work using pseudopeptidic bottlebrush polymers. Due to their huge size and highly populated side chains, bottlebrush polymers, also known as molecular brushes, are excellent candidates for photonics, drug delivery, energy storage, and medicinal devices.…”

“…[49][50][51] We recently investigated the impact of bottlebrush polymer molecular weight variation on the performance of light scattering switches and on the modulation of LC matrix characteristics. 27,46 This work aims to design and synthesize amino acid-based bottlebrush polymer matrix with different appendages to establish a controlled LC director configuration in PDLC for sensing applications. For this, a series of pseudopeptidic polymers having aromatic (phenyl) and aliphatic appendages are synthesized.…”
