【Abstract】 The screen printing technology has been improved to fabricate carbon nanotube field emission cath- ode,so materials the preparation research of carbon nanotubes arrays is key for applications in the field emission flat display.In this paper,the preparation methods of carbon nanotube field emission cathode arrays such as screen print- ing,CVD in situ growth,light-chisel,self-organize and so on are introduced and the development is also reviewed.The development of the optinization of CNTs field emission capability is summarized aiming at wiping off the leftover in film,changing CNTs micro-structure and enhancing sp~3 lacuna.Some problems and solutions are proposed too.更多还原
