Carbon nanomembranes on porous materials

Abstract

A method for manufacturing a porous device ( 10 ) is described. The method comprises creating ( 340 ) a carbon nanomembrane ( 40 ) on a top surface ( 22 ) of a base material ( 20 ) having latent pores ( 23 ) and etching ( 360 ) the latent pores ( 23 ) in the base material ( 20 ) to form open pores ( 24 ). The porous device ( 10 ) can be used as a filtration device.

What is claimed is: 
     
         1 . A porous device comprising a base material with a plurality of open pores created from latent pores and a carbon nanomembrane on a top surface of the base material. 
     
     
         2 . The porous device of  claim 1 , further comprising a buffer layer between the carbon nano membrane and the top surface of the base material. 
     
     
         3 . The porous device of  claim 1 , wherein the carbon nano membrane comprises laterally cross-linked aromatic compounds. 
     
     
         4 . The porous device of  claim 3 , wherein the aromatic compounds are selected from the group consisting of phenyl-containing compounds. 
     
     
         5 . The porous device of  claim 3 , wherein the aromatic compounds are at least one of a phenyl, biphenyl, terphenyl or quaterphenyl moiety. 
     
     
         6 . Use of the porous device of  claim 1  as a filtration device or in a forward osmosis process.
