Abstract
Disclosed are processes for producing monolithic and metal doped monolithic porous carbon disks from prepolymer organic precursors in the powder form composed of either or both polyimide and polybenzimidazole. The powders are consolidated (compressed) into disks and then pyrolyzed to form the desired porous carbon disk. Porous carbon-carbon composite disks are also prepared by adding carbon to the prepolymer organic precursors.
Claims
exact text as granted — not AI-modified1 - 26 . (canceled)
27 . A monolithic porous carbon-carbon composite made by a process comprising the steps of:
preparing a precursor powder comprising either or both polymide and polybenzimidazole; consolidating the precursor powder under pressure; and pyrolyzing the monolith in an inert atmosphere or carbon dioxide to form a monolithic porous carbon disk.
28 . A monolithic porous carbon-carbon composite made by the method of claim 27 wherein the process further comprises adding carbon to the precursor powders to form a monolithic porous carbon-carbon composite disk.
