A vacuum packaging system includes a vacuum room, a delivery apparatus, a discharge device, a second heating apparatus. The delivery apparatus transport the pre-packaged container into the vacuum room. The discharge device discharges a sealing material to seal an exhaust through hole of the pre-packaged container. The discharge device includes a vessel configured for containing sealing material, a transport pipeline, a first heating, and a controlling element. The first heating apparatus softens the sealing material into viscous liquid. The second heating apparatus is mounted on the inner wall of the vacuum room between the second hatch and the transport pipeline.

A method for forming a patterned array of carbon nanotubes (11) includes the steps of: forming an array of carbon nanotubes on a substrate (10); imprinting the array of carbon nanotubes using a molding device (12) with a predetermined pattern; and removing the molding device, thereby leaving a patterned array of carbon nanotubes (13). The method can effectively reduce or even eliminate any shielding effect between adjacent carbon nanotubes, and is simple to implement. The field emission performance of the patterned array of carbon nanotubes is improved.
