METHOD FOR MANUFACTURING FIELD EMISSION CATHODE

摘要

A method for manufacturing a carbon nanotube/polymer composite includes the steps of: (a) providing a carbon nanotube array formed on a substrate in a container; (b) providing a prepolymer of polymethyl methacrylate (PMMA); (c) putting the prepolymer into the container for a period of over 30 minutes to fill in clearances of the carbon nanotube array; and (d) polymerizing the prepolymer film at a temperature of about 50° C. to 60° C. for a period of about 1 hour to 4 hours and then heating the prepolymer film to about 90° C. to 100° C. to form a polymer film, the carbon nanotube array thereby being embedded within the polymer film.
