Abstract Scope Colloidal suspensions of micrometer-size particles in a liquid form gels when the attractive interaction between the particles makes them aggregate into solid, system-spanning networks.One source of attraction is depletion: small polymers, added to the solution, are excluded from a thin depletion zone around each particle; overlap of these zones increases the volume available to the polymers and hence the entropy of the system. The aggregates are partially amorphous and continue to crystallize after the networks are formed. The initial rates of crystallization can be understood by the competition of densification and kinetic suppression. The crystallized fraction can be increased by oscillatory shear straining of the gel. With confocal microscopy, we can view directly how the deformation creates local interfacial configurations that allow further crystallization.
