Claims25
A ceramic aerogel comprising a porous framework including interconnected double-paned wall structures of a ceramic material, wherein each double-paned wall structure includes a pair of walls spaced apart by a gap;
- wherein the gap between the pair of walls is from 1 nm to 50 nm.
A method of forming a ceramic aerogel, comprising:
- providing a template, wherein the template is an aerogel of a template material;
- depositing a ceramic material on and within the template;
- and
- removing the template material to form the ceramic aerogel having a double-paned wall structure including a pair of walls spaced apart by a gap;
- wherein the gap between the pair of walls is from 1 nm to 50 nm.
A ceramic aerogel comprising a fibrous framework and interconnected nanosheets of a ceramic material covering the fibrous framework;
- wherein the interconnected nanosheets have a double-paned wall structure including a pair of walls spaced apart by a gap;
- wherein the gap between the pair of walls is from 1 nm to 50 nm.
