Abstract
Methods for making porous nanotube fabrics are disclosed. Within the methods of the present disclosure, a porogen-loaded nanotube application solution is formed by combining a first volume of nanotube elements with a second volume of fuel material in a liquid medium to form a porogen-loaded nanotube application solution. In some aspects of the present disclosure, a third volume of oxidizer material is also combined into the liquid medium. A porogen-loaded nanotube fabric is formed by depositing the porogen-loaded nanotube application solution. In some aspects of the present disclosure, the fuel material within the porogen-loaded nanotube application solution will react with oxidizer material when heat is applied to a sufficient degree and volatize. The off-gassed fuel material will then leave behind voids in the nanotube fabric, rendering the fabric porous.
