Abstract
A method for making a diaphragm is disclosed. The method includes the steps of: providing a carbon nanotube film structure; soaking the carbon nanotube film structure with a polymer; and carbonizing the carbon nanotube film structure infiltrated in the polymer, the polymer being carbonized to an amorphous carbon structure.
Claims14
A method for making a diaphragm, comprising:
- providing a carbon nanotube film structure, wherein the carbon nanotube film structure is a free-standing structure and defines a plurality of micropores;
- soaking the carbon nanotube film structure with a polymer to form a composite, wherein the soaking the carbon nanotube film structure with the polymer comprises the polymer filling the plurality of micropores and combining with the carbon nanotube film structure, and the polymer and the carbon nanotube film structure are combined by van der Waals attractive forces and covalent bonds therebetween;
- and
- carbonizing the composite comprising the carbon nanotube film structure and the polymer at a carbonization temperature, the polymer being carbonized to form an amorphous carbon structure.
