Abstract:
1. A method of forming optically transparent and electrically conductive single walled carbon nanotubes (SWNT) films, comprising the steps of: providing a porous membrane; dispersing a plurality of single walled carbon nanotubes (SWNTs) into a solution, said solution including at least one surface stabilizing agent for preventing said SWNTs from flocculating out of suspension; applying said solution to said membrane, removing said solution, wherein said SWNTs are forced onto a surface of said porous membrane to form an optically transparent SWNT film comprising a plurality of interpenetrated single walled carbon nanotubes disposed on said membrane, wherein a thickness of said SWNT film is <300 nm, and separating said SWNT film from said membrane, wherein said separating step comprises dissolving said membrane in a solvent or digestion of said membrane in an acid; wherein said SWNT film provides a bulk resistivity ≦2×10
