Abstract
The present application is generally directed to activated carbon materials and methods for making the same. The disclosed methods comprise rapidly freezing synthetically prepared polymer gel particles. The methods further comprise drying, pyrolyzing, and activating steps to obtain an activated carbon material of high porosity. The disclosed methods represent viable manufacturing processes for the preparation of activated carbon materials.
Claims26
A method for preparing a polymer cryogel, the method comprising:
- A) admixing polymer precursors and a catalyst in a solvent to obtain a mixture;
- B) allowing the mixture to polymerize to form a gel;
- and
- C) freeze drying the gel to obtain a polymer cryogel,
- wherein the solvent is not exchanged for an organic extraction solvent prior to freeze drying.
