Imprinting Macroscopic Fracture during Gelation: A Mechanism for Tuning Colloidal Gels
Wilbert J. Smit, Thomas Gibaud, Sébastien Manneville +1
Colloidal gels form through the sol-gel transition of attractive particle suspensions, where local aggregation leads to a space-spanning network with solid-like properties. Their m…
LAOStrain response of carbon black-polymer hydrogels: insights from rheo-TRUSAXS and rheo-electric experiment
Gauthier Legrand, Guilhem P. Baeza, William Chèvremont +2
Colloid-polymer hydrogels are encountered in various applications, from flow batteries to drug delivery. Here, we investigate hydrogels composed of hydrophobic colloidal soot parti…
Anti-thixotropic dynamics in attractive colloidal dispersions: a shear restructuring driven by elastic stresses
Julien Bauland, Gauthier Legrand, Sébastien Manneville +3
Due to rich rheological properties, dispersions of attractive colloidal particles are ubiquitous in industries. Specifically, upon experiencing a sudden reduction in shear rate, th…
Delayed recovery in a dense suspension of core-shell attractive particles
Justine Henry, Ludovic Feige, Clara Paillard +1
Soft particulate glasses are dense suspensions of jammed particles that flow like liquids under external shear and recover their solid-like properties almost instantly upon flow ce…
Understanding Polymer-Colloid Gels: A Solvent Perspective Using Low-Field NMR
Léo Hervéou, Gauthier Legrand, Thibaut Divoux +1
The present work emphasizes the relevance of low-field NMR relaxometry to investigate colloid-polymer hydrogels by probing water dynamics across a wide range of formulations betwee…
Rheological properties of acid-induced carboxymethylcellulose hydrogels
Gauthier Legrand, Guilhem P. Baeza, Sébastien Manneville +1
Cellulose ethers represent a class of water-soluble polymers widely utilized across diverse sectors, spanning from healthcare to the construction industry. This experimental study…
