摘要：

Rheology and dynamics of micellar solutions of polystyrene-poly(acrylic acid) block copolymers are investigated in the jammed regime. With increasing attraction between soft spheres, both techniques capture the re-entrant liquid-to-glass transition. The dynamics was also investigated at an attraction strength above the re-entrant transition branch. With increasing concentration of sticky soft spheres in this region, the particle dynamics shows a remarkable extended logarithmic decay. All the theoretical predictions of mode coupling theory can be found in our system.
