A membrane and use thereof

摘要

The invention provides the use of a membrane comprising a support layer and an electrically conductive porous nanotube layer for generating power from water by pressure retarded osmosis. The electrically conductive nanotubes may be arranged in a mat, alternatively the electrically conductive nanotubes may be orientated with respect to the support layer. The electrically conductive nanotubes may be carbon nanotubes. The electrically conductive nanotubes may be single walled nanotubes and/or double walled nanotubes and/or multiwalled nanotubes. The electrically conductive nanotubes may be functionalised.
