Abstract
A novel method for producing a structure having cavities is disclosed. The method comprises a first step of coating a colloidal dispersion liquid on a substrate and then drying to thereby form a layer of colloidal beads on said substrate; a second step of forming a film comprising a metal and/or metal compound on surfaces of said colloidal beads placed on said substrate; and a third step of removing said colloidal beads thereby to form cavities in place of said colloidal beads.
Claims18
A method for producing a structure having cavities comprising:
- a first step of coating a colloidal dispersion liquid on a substrate and then drying to thereby form a layer of colloidal beads on said substrate;
- a second step of forming a film comprising a metal and/or metal compound on the surfaces of said colloidal beads placed on said substrate;
- and
- a third step of removing said colloidal beads thereby to form cavities in place of said colloidal beads.
A structure comprising a substrate and a plurality of structural units made of a metal and/or metal compound, wherein each of said structural units has a form of hollow cup with its opening toward said substrate and is arranged according to a continual arrangement.
A method for producing a structure having fine particles regularly arranged on a substrate, said method comprising:
- a first step of coating a colloidal dispersion liquid on a substrate and then drying to thereby form a layer of colloidal beads on said substrate;
- a second step of forming a film comprising a metal and/or metal compound on the surface of said colloidal beads placed on said substrate;
- a third step of removing said colloidal beads thereby to form cavities in place of said colloidal beads;
- and
- a fourth step of fusing and collapsing said film by heating to thereby transform into said fine particles,
- wherein said fourth step is carried out simultaneously with said third step or after said third step.
