Abstract: The MWCNT/ZnO nanowires composite material has been proposed as field emission cathode films in this paper,the graphic fabrication process and the field emission characteristics have also been studied.A series of MWCNT/ZnO nanowires composite cathode films,upon which the graph was drew,have been produced using the screen printing method.The influence of the protection flow in sintering process has been studied,and the suitable slurry proportion and sintering temperature have been obtained.The SEM analysis has been used to study and discuss the morphology of the samples of MWCNT/ZnO nanowires.The graphic MWCNT/ZnO nanowires composite films have been carried out to compare the differences between field emission characteristics of graphic and non-graphic samples.Finally,the influence factors of field emission characteristics have been discussed,including different proportion of MWCNT/ZnO nanowires,selection of ZnO nanowires or ZnO powder,electrical aging treatment,and so on.A simple analysis to the luminescence photos has also been given.
