Self Organization of Colloidal Dispersion in Microgravity

Abstract

Microgravity experiments on colloidal self organization are described especially for the colloidal crystallization kinetics, rotational diffusion and synthesis of colloidal particles. A gravitational field is one of the important parameters for the physico-chemical properties of colloidal dispersion systems. This overview introduces the large microgravity effects on the colloidal systems, such that ) colloidal crystallization is retarded, ) crystallization for the colloidal alloy systems is enhanced, 3) accurate determination of the rotational diffusion constants is available, 4) vesicles are formed from the polycondensation of ylon, and 5) formation reaction of colloidal silica spheres is retarded.
