Abstract
ABSTRACT The smectic-A to chiral smectic-C* (SmA–SmC*) phase transition in the mixture of graphene nanoparticles and ferroelectric liquid crystal is studied. Combination of Flory–Huggins free energy of isotropic mixing and Landau theory is applied to explain the effects of graphene nanoparticles on the SmA–SmC* phase transition. The temperature and concentration of graphene nanoparticles dependence of tilt angle, spontaneous polarization and dielectric susceptibility in the smectic-C* phase of the SmA–SmC* phase transition are discussed. A qualitative agreement between theoretical results and experimental results is found.
期刊介绍：
Providing a common forum for all soft matter scientists, Soft Materials covers theory, simulation, and experimental research in this rapidly expanding and interdisciplinary field. As soft materials are often at the heart of modern technologies, soft matter science has implications and applications in many areas ranging from biology to engineering.
Unlike many journals which focus primarily on individual classes of materials or particular applications, Soft Materials draw on all physical, chemical, materials science, and biological aspects of soft matter. Featured topics include polymers, biomacromolecules, colloids, membranes, Langmuir-Blodgett films, liquid crystals, granular matter, soft interfaces, complex fluids, surfactants, gels, nanomaterials, self-organization, supramolecular science, molecular recognition, soft glasses, amphiphiles, foams, and active matter.
Truly international in scope, Soft Materials contains original research, invited reviews, in-depth technical tutorials, and book reviews.
