colloids, colloidal materials, "directed" assembly, rheology, suspensions


This article summarizes several new developments of colloid science in two aspects: "directed" assembly of colloidal particles and understanding in rheology of colloidal suspensions.

Directed Assembly

1) Using depletion interaction

  Controllable elements: 1.surface treatment  2.solvent choice  3.addition of other materials

2) Applying additional stresses
