Abstract

The 'phase diagram' of a non-Brownian carbon nanotube suspension is measured as a function of concentration, shear stress, and geometrical confinement. We observe a hierarchy of flow-induced structure, including dispersed 'nematics', isolated, periodic and percolated aggregates, and 'jammed' fractal networks. By applying simple scaling arguments to rigid-rod gels, our data suggest that the jamming portion of the network is more diffuse than the full elastic network, akin to 'force chains' in granular media.
