Shear-Driven Solidification of Dilute Colloidal Suspensions / A. Zaccone, D. Gentili, H. Wu, M. Morbidelli, E. Del Gado. - In: PHYSICAL REVIEW LETTERS. - ISSN 0031-9007. - 106:13(2011), pp. 138301.1-138301.4.
Abstract:
We show that shear-induced solidification of dilute charge-stabilized colloids is due to the interplay between shear-induced formation and breakage of large non-Brownian clusters. While their size is limited by breakage, their number density increases with shearing time. Upon flow cessation, the dense packing of clusters interconnects into a rigid state by means of grainy bonds, each involving a large number of primary colloidal bonds. The emerging picture of shear-driven solidification in dilute colloidal suspensions combines the gelation of Brownian systems with the jamming of athermal systems.
