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
Liquid-crystalline nematic phase in aqueous suspensions of a disk-shaped natural beidellite clay.
Erwan Paineau,Krassimira Antonova,C. Baravian,Isabelle Bihannic,Patrick Davidson,Ivan Dozov,Marianne Impéror-Clerc,P. Levitz,Anders Madsen,Florian Meneau,L. J. Michot +10 more
TL;DR: After size-selection and osmotic pressure measurements at fixed ionic strength, the behavior of aqueous colloidal suspensions of anisotropic disklike beidellite clay particles has been investigated by combining optical observations under polarized light, rheological, and small angle X-ray scattering (SAXS) experiments.
Journal ArticleDOI
Water in Carbon Nanotubes: The Peculiar Hydrogen Bond Network Revealed by Infrared Spectroscopy
Simona Dalla Bernardina,Erwan Paineau,J.-B. Brubach,Patrick Judeinstein,Stéphan Rouzière,Pascale Launois,Pascale Roy +6 more
TL;DR: The first infrared study of water uptake at controlled vapor pressure in single walled carbon nanotubes with diameters ranging from 0.7 to 2.1 nm is reported, revealing a predominant contribution of loose H bonds even for fully hydrated states, irrespective of the nanotube size.
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
A liquid-crystalline hexagonal columnar phase in highly-dilute suspensions of imogolite nanotubes
Erwan Paineau,Marie-Eve M. Krapf,Mohamed-Salah Amara,Natalia V. Matskova,Ivan Dozov,Stéphan Rouzière,Antoine Thill,Pascale Launois,Patrick Davidson +8 more
TL;DR: It is shown that one of the four major lyotropic liquid-crystal phases, the columnar one, is much more stable on dilution than reported so far in literature, and should have important implications for the statistical physics of the suspensions of charged rods.
