Abstract
A polymer membrane is formed around nanotubes by applying either droplets or a thin film of a suspension of the nanotubes over a layer of a solution of the polymer, the suspending medium for the nanotubes and the solvent(s) for the polymer selected such that the suspending agent will evaporate while it is migrating into and dispersing in the solvent. When the polymer is then permitted to coagulate around the nanotubes, the coagulated polymer will fix the orientations of the nanotubes and a high proportion of the nanotubes will protrude from both sides of the resulting membrane to provide through-passages through the membrane.
