Journal ArticleDOI
Liquid–crystalline aqueous clay suspensions
Laurent J. Michot,Isabelle Bihannic,Solange Maddi,Sérgio S. Funari,Christophe Baravian,Pierre Levitz,Patrick Davidson +6 more
TL;DR: Small-angle x-ray scattering measurements of gel samples reveal strong positional and orientational orders of the particles, proving unambiguously the nematic character of the gel and, thus, clearly refuting the still prevalent “house of cards” model.
Journal ArticleDOI
Phase Diagrams of Wyoming Na-Montmorillonite Clay. Influence of Particle Anisotropy
Laurent J. Michot,Isabelle Bihannic,Katharina Porsch,Solange Maddi,Christophe Baravian,Julien Mougel,Pierre Levitz +6 more
TL;DR: Interacting clay particles are amenable to generate, at rest and/or under shear, large anisotropic particle associations that are not directly related to an isotropic/nematic transition of individual clay particles.
Journal ArticleDOI
Aqueous Suspensions of Natural Swelling Clay Minerals. 1. Structure and Electrostatic Interactions
Erwan Paineau,Isabelle Bihannic,Christophe Baravian,Adrian-Marie Philippe,Patrick Davidson,Pierre Levitz,Se rgio S. Funari,Cyrille Rochas,Laurent J. Michot +8 more
TL;DR: An overview of the organization of colloidal charged clay particles in aqueous suspension is presented by studying different natural samples with different structural charges and charge locations through a detailed investigation of the structure factors of the various clay samples.
Journal ArticleDOI
Aqueous suspensions of natural swelling clay minerals. 2. Rheological characterization.
TL;DR: A comprehensive investigation of the viscoelastic behavior of different natural colloidal clay minerals in aqueous solution was reported, pointing out that in the high shear limit the suspension viscosity is still closely related to electrostatic interactions and follows the same trends as the vis coelastic properties.
Journal ArticleDOI
Electric-field-induced perfect anti-nematic order in isotropic aqueous suspensions of a natural beidellite clay.
Ivan Dozov,Erwan Paineau,Patrick Davidson,Krassimira Antonova,Christophe Baravian,Isabelle Bihannic,Laurent J. Michot +6 more
TL;DR: The excess polarizability of the isotropic regions of biphasic nematic/isotropic samples is proposed to be due to pretransitional fluctuations of the spontaneous nematic order S(N) of the colloidal suspension and/or formation of chains of particles, with antinematic order of the beidellite disks in the chains.
