Method of forming graphene nanomesh

Abstract

A graphene nanomesh includes a graphene sheet having a plurality of pores formed therethrough. Each pore has a first diameter defined by an inner edge of the graphene sheet. A plurality of passivation elements are bonded to the inner edge of each pore. The plurality of passivation elements defines a second diameter that is less than the first diameter to decrease an overall diameter of at least one pore among the plurality of pores.

 a graphene sheet having a plurality of pores formed therethrough, each pore having a first diameter defined by an inner edge of the graphene sheet; and   a plurality of passivation elements bonded to the inner edge of each pore, the plurality of passivation elements defining a second diameter that is less than the first diameter to decrease an overall diameter of at least one pore among the plurality of pores.   
     
     
         2 . The graphene nanomesh of  claim 1 , wherein active carbon sites are formed at the inner edge of each pore, the passivation elements configured to bond to the active carbon sites.

The graphene nanomesh of  claim 3 , wherein a first end of the passivation elements is configured to bond to the active carbon sites and an opposite end of the passivation elements is configured to bond to at least one molecule introduced to the graphene nanomesh to prevent the at least one molecule from traveling through a nanopore. 
     
     
         8 . The graphene nanomesh of  claim 7 , wherein the opposite end of the passivation elements selectively bonds to a first molecule while allowing a second molecule different from the first molecule to travel through the nanopore. 
     
     
         9 . The graphene nanomesh of  claim 1 , wherein the second diameter is less than 1 nanometer.
