Microrheology of attractive gels formed by critical Casimir forces

Can Tho University

We report an experimental study of aging colloidal gels formed by attractive critical Casimir forces. These forces allow us to directly tune the particle interactions with temperature as a control parameter. These experimental results show a stiffening of the network elasticity of the attractive colloidal gels with aging time. We also propose a simple model to interpret the structural origin of colloidal aggregates at the particle level. Our results provide new insights into network elasticity on aging attractive gels.
