METHOD FOR PRODUCING COLLOIDAL CRYSTAL, AND COLLOIDAL CRYSTAL

• 特願2011-050064 (2011.3.8) JP

[Problem] To provide a method for producing a colloidal crystal, which can be easily controlled and is capable of flexibly dealing with a wide range of the kinds of colloidal particles. [Solution] A method for producing a colloidal crystal of the present invention is characterized by comprising: a preparation step for preparing a colloidal dispersion liquid which is obtained by dispersing colloidal particles in a liquid that contains an ionic surfactant and which is capable of precipitating a colloidal crystal by means of temperature change

and a crystallization step for precipitating a colloidal crystal by changing the temperature of the colloidal dispersion liquid from a temperature range within which a colloidal crystal is not precipitated to a temperature range within which a colloidal crystal is precipitated.
