HIGH SURFACE AREA CARBON OPALS AND INVERSE OPALS OBTAINED FROM THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a self assembled carbon structure having heat stability usable as a template in manufacturing of inverse opals, and an inverse opal structure obtained from the same.SOLUTION: A carbon is made of hydrophilic carbon sphere arrayed in a periodic colloidal crystal structure and has a porous surface and a mean particle diameter of less than 3000 nm. A inverse opal structure including a plurality of voids in structural materials is disclosed. Voids are regularly arrayed in orderly periodic structures and have a sphere shape. The inverse opal has a specific surface area of more than 100 m/g.
