POROUS FILMS BY A TEMPLATING CO-ASSEMBLY PROCESS

摘要

A method of making a composite includes providing a particle suspension comprising colloidal particles (430) and a soluble matrix precursor (440); and co-depositing the particles and the matrix precursor on a surface in a process that provides a composite of an ordered colloidal crystal comprised of colloidal particles (430) with interstitial matrix (440). Optionally the templated colloidal particles can be removed to provide a defect-free inverse opal structure.
