Two‐ and Three‐Dimensional Ordered Structures of Hollow Silver Spheres Prepared by Colloidal Crystal Templating

Abstract

The preparation of ordered arrays of metal hollow spheres via colloidal crystal templating is reported. A seeded growth technique for metal coatings on isolated colloids in solution and a confined template‐directed synthesis method for metal patterning were combined. The polymer colloidal crystal template was prepared and kept stable using a microchannel. 2D and 3D ordered microstructures of silver hollow spheres were obtained (see Figure).
