urn:hdl:2445/127830 Chemical Leslie effect in Langmuir monolayers: a complete experimental characterization Bunel, Felix Ignés i Mullol, Jordi Sagués i Mestre, Francesc Oswald, Patrick Química de superfícies Quiralitat Cristalls líquids Surface chemistry Chirality Liquid crystals We propose a complete characterization of the chemical Leslie effect in a Langmuir monolayer of a chiral liquid crystal. To reach this goal, we developed new experimental techniques using an electric field and a humidifier to prepare large monodomains in which the molecules can freely rotate. We also designed six independent experiments to precisely measure the four material constants involved in the dynamics of the monolayer, namely the Leslie coefficient, the rotational viscosity, the curvature elasticity constant and the surface polarization. The relevance of the inverse Leslie effect is also discussed. 2019-02-04T08:00:26Z 2019-06-21T05:10:14Z 2018-06-21 2019-02-04T08:00:26Z info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Versió postprint del document publicat a: https://doi.org/10.1039/c8sm00933c Soft Matter, 2018, vol. 14, num. 23, p. 4835-4845 https://doi.org/10.1039/c8sm00933c (c) Bunel, Felix et al., 2018 info:eu-repo/semantics/openAccess Royal Society of Chemistry Articles publicats en revistes (Ciència dels Materials i Química Física)
