Abstract
A membrane is electrically charged to a polarity. A surface of carbon nanotubes (CNTs) in a solution is caused to acquire a charge of the polarity. The solution is filtered through the membrane. An electromagnetic repulsion between the membrane of the polarity and the CNTs of the polarity causes the CNTs to spontaneously align to form a crystalline structure.
