| Abstract | We report on experiments on the rheology of gels formed by diffusion-limited aggregation of neutrally buoyant colloidal particles. These gels form very weak solids, with the elastic modulus, G 0 svd, larger than the loss modulus, G 00 svd, and with both G 0 svd and G 00 svd exhibiting only a very weak frequency dependence. Upon small but finite strains g, 0.45 the elastic modulus increases roughly exponentially with g 2 . We explain the observed strain hardening with the highly nonlinear elastic response of the rigid backbone of the gel to elongational deformation. [S0031-9007(98)08309-4] |
