Glass-like dynamics of the strain-induced coil/helix transition on a permanent polymer network
O. Ronsin, C. Caroli, T Baumberger
We study the stress response to a step strain of covalently bonded gelatin gels in the temperature range where triple helix reversible crosslink formation is prohibited. We observe…
Two-step build-up of a thermoreversible polymer network: From early local to late collective dynamics
H. Souguir, O. Ronsin, C. Caroli +1
We probe the mechanisms at work in the build-up of thermoreversible gel networks, with the help of hybrid gelatin gels containing a controlled density of irreversible, covalent cro…
Magic angles and cross-hatching instability in hydrogel fracture
Tristan Baumberger, Christiane Caroli, David Martina +1
The full 2D analysis of roughness profiles of fracture surfaces resulting from quasi-static crack propagation in gelatin gels reveals an original behavior characterized by (i) stro…
Fracture of a biopolymer gel as a viscoplastic disentanglement process
Tristan Baumberger, Christiane Caroli, David Martina
We present an extensive experimental study of mode-I, steady, slow crack dynamics in gelatin gels. Taking advantage of the sensitivity of the elastic stiffness to gel composition a…
Non-Amontons behavior of friction in single contacts
Lionel Bureau, Tristan Baumberger, Christiane Caroli
We report on the frictional properties of a single contact between a glassy polymer lens and a flat silica substrate covered either by a disordered or by a self-assembled alkylsila…
