Manufacturing methods for carbon nanotube self-supporting films and protective film components

Abstract

This invention provides a method for manufacturing a self-supporting carbon nanotube membrane and a method for manufacturing a protective membrane assembly. The method for manufacturing the self-supporting carbon nanotube membrane is characterized by: forming a carbon nanotube membrane 1 on a membrane filter 10, such that the thickness of the outer periphery 1b of the carbon nanotube membrane is greater than the thickness of the inner diameter 1a of the carbon nanotube; connecting a first frame-shaped member 2 to the outer periphery 1b of the carbon nanotube membrane; and separating the carbon nanotube membrane 1 from the membrane filter 10. The method for manufacturing the protective membrane assembly involves, after manufacturing the self-supporting carbon nanotube membrane 1, using a second frame-shaped member 3 with a frame size smaller than the first frame-shaped member 2, so that the self-supporting carbon nanotube membrane 1 serves as the protective membrane 1c and the second frame-shaped member 3 serves as the frame of the protective membrane assembly. This invention enables the stable manufacture of a self-supporting carbon nanotube membrane into a protective membrane assembly.
