Abstract: Rapid progress in investigations of the field-electron emission from polymer-carbon nanotube composite cathodes poses a key question concerning the effect of the properties of matrix molecules on the parameters of emission. In this context, the results of a comparative investigation of the characteristics of field-electron emitters prepared from compositions based on various polymer matrices are presented. Data on the influence of rigidity and polarity of macromolecules on the emissivity of nanocomposite emitters have been obtained for the first time.
