Abstract
High-strength porous carbon and a method of its manufacture are described for multifunctional applications, such as ballistic protection, structural components, ultracapacitor electrodes, gas storage, and radiation shielding. The carbon is produced from a polymer precursor via carbonization, and optionally by surface activation and post-treatment.
Claims25
A protective assembly, comprising:
- as an article of manufacture, a garment to be worn by an individual;
- and at least one high-strength porous carbon member operatively assembled with said article of manufacture, said carbon member being the product of a method for the production of high-strength porous carbon, comprising the following steps, carried out in the order set forth:
- a. providing a suitable sorbent precursor material that is subject to carbonization;
- b. effecting carbonization of said sorbent precursor material by heat-treatment in a non-oxidizing atmosphere;
- c. optionally effecting activation of said carbonized sorbent precursor material using any suitable method;
- d. optionally effecting heat-treatment of said carbonized sorbent precursor material at a temperature in the range of about 800° C. to about 2,000° C.;
- and
- e. optionally conditioning the surface of said heat-treated sorbent precursor material by contacting said surface with a reducing gas,
- said suitable sorbent precursor material being a material selected from the group consisting of polyvinylidene chloride (PVDC), polyfurfuryl alcohol, phenolic resin, and blends of these materials.
