Abstract: |
A field transmission cathode manufacturing method is provided, which comprises the following procedures: provide a carbon nanometer tube array growing on a basis; configure methacrylic acid methyl ester semi-polymerized solution; fill the semi-polymerized solution to a vessel with carbon nanometer tube array for over 30 minutes; fix the vessel on a rotary stage with the speed of 200 to 600 rounds/minute for rotation; remove the methacrylic acid methyl ester polymerized material on the upper end of the carbon nanometer tube array, so as to form a film with preliminary polymerization; heat the film with preliminary polymerization to 50 DEG C. to 60 DEG C. and continue the polymerization for 1 to 4 hours; then, heat the film to 90 DEG C. to 100 DEG C., so as to from fully polymerized carbon nanometer tube-methacrylic acid methyl ester film; immerse the fully polymerized film in water for over 5 minutes; the film detaches completely from the basis; then, place the film on a conductance electrode to form the field transmission cathode. |
