Partition of Coating Agents between Nanoparticle Interfaces and the Polymer in Nanocomposites
Dafne Musino, Julian Oberdisse, Michael Sztucki +2
Industrial and model polymer nanocomposites are often formulated with coating agents to improve polymer-nanoparticle (NP) compatibility. Here the localization of silane coating age…
Packing polydisperse colloids into crystals: when charge-dispersity matters
Guillaume Bareigts, Pree-Cha Kiatkiakajorn, Joaquim Li +5
Monte-Carlo simulations and small-angle x-ray scattering experiments were used to determine the phase diagram of aqueous dispersions of titratable nano-colloids with a moderate siz…
Rheo-acoustic gels: Tuning mechanical and flow properties of colloidal gels with ultrasonic vibrations
Thomas Gibaud, Noémie Dagès, Pierre Lidon +7
Colloidal gels, where nanoscale particles aggregate into an elastic yet fragile network, are at the heart of materials that combine specific optical, electrical and mechanical prop…
Hiding in plain view: Colloidal self-assembly from polydisperse populations
Bernard Cabane, Joaquim Li, Franck Artzner +5
We report small-angle x-ray scattering (SAXS) experiments on aqueous dispersions of colloidal silica with a broad monomodal size distribution (polydispersity 18%, size 8 nm). Over…
Tuning Structure and Rheology of Silica-Latex Nanocomposites with the Molecular Weight of Matrix Chains: A Coupled SAXS-TEM-Simulation Approach
Amélie Banc, Anne-Caroline Genix, Mathieu CHIRAT +4
The structure of silica-latex nanocomposites of three matrix chain masses (20, 50, and 160 kg/mol of poly(ethyl methacrylate)) are studied using a SAXS/TEM approach, coupled via Mo…
Structural anisotropy of directionally dried colloids
François Boulogne, Ludovic Pauchard, Frédérique Giorgiutti-Dauphiné +6
Aqueous colloidal dispersions of silica particles become anisotropic when they are dried through evaporation. This anisotropy is generated by a uniaxial strain of the liquid disper…
Viscosity and Diffusion: Crowding and Salt Effects in Protein Solutions
Marco Heinen, Fabio Zanini, Felix Roosen-Runge +9
We report on a joint experimental-theoretical study of collective diffusion in, and static shear viscosity of solutions of bovine serum albumin (BSA) proteins, focusing on the depe…
Observation of empty liquids and equilibrium gels in a colloidal clay
Barbara Ruzicka, Emanuela Zaccarelli, Laura Zulian +5
The relevance of anisotropic interactions in colloidal systems has recently emerged in the context of the rational design of new soft materials. Patchy colloids of different shapes…
Competing interactions in arrested states of colloidal clays
B. Ruzicka, L. Zulian, E. Zaccarelli +4
Using experiments, theory and simulations, we show that the arrested state observed in a colloidal clay at intermediate concentrations is stabilized by the screened Coulomb repulsi…
Arrested state of clay-water suspensions: gel or glass?
B. Ruzicka, L. Zulian, R. Angelini +3
The aging of a charged colloidal system has been studied by Small Angle X-rays Scattering, in the exchanged momentum range Q=0.03 - 5 nm-1, and by Dynamic Light Scattering, at diff…
