Abstract
A nanoporous network includes carbon nanotubes (CNTs) with the network having a pore size in a range from about 15 nm to about 35 nm. The nanoporous network can be coated, compressed, or any combination of these operations in the manufacture of various articles. A method of making a nanoporous network includes disposing a concentrated aqueous CNT solution in a mold, freezing the concentrated aqueous CNT solution, and subliming the frozen concentrated CNT solution in a vacuum chamber.
Claims6
A nanoporous network consisting of surfactant-free carbon nanotubes (CNTs) that contact one another to form a three-dimensional array, said nanoporous network having pores defined between the carbon nanotubes that have a pore size range from about 15 nm to about 35 nm with less than about 10% outlier pore sizes outside this range;
- wherein no outlier pore sizes are more than about 100 nm in size.
