Abstract
- We measure the dynamical arrest transition in a model, thermoreversible, adhesive hard sphere dispersion. At low volume fractions ɸ, below the critical point, gelation occurs within the gas-liquid phase boundary. For ɸ slightly below and above the critical concentration, the phase boundary follows the predicted percolation transition. At high ɸ, it melds into the predicted attractive-driven glass transition. Our results demonstrate that for ɸ above ~20% physical gelation is an extension of the attractive-driven glass line and occurs without competition for macroscopic phase separation.
