Abstract
The present invention provides an emissive material with excellent electron emission characteristics. In particular, the present invention relates to a method for manufacturing an emissive material consisting of oriented graphite, having a step of obtaining an oriented graphite comprising a second component and having pores on the inside by heat treating a polymer film in the presence of a second, non-carbon component.
Claims19
A method for manufacturing an electron-emitting material consisting of oriented graphite, the oriented graphite having a sheet form and emitting an electron from an upper surface, the method comprising a step of heat-treating a polymer film with a particulate component, which serves as a second component other than carbon and is arranged on the upper surface of the polymer film, for forming the polymer film to obtain an oriented graphite with a density of no less than 0.60 g/cm3 and no more than 2.00 g/cm3 which comprises the second component and has pores inside.
