The　main　problem　of　printed　carbon　nanotube　film　(CNTF)　is　that　emitters　do　not　have　distributed　uniformity.　CNT　was　buried　in　leftover　binding　materials,　which　needs　to　be　removed　by　fitted　sintering　and　post-treatment.　A　new　paste　for　printed　CNTF　was　developed.　Tunneling　coefficients　of　leftover　potential　barrier　were　calculated　respectively　by　the　numerical　method.　The　electrons　translocation　results　through　potential　barrier　between　CNTs　in　calculated　CNTF　were　tested　by　an　experiment.　A　novel　post-treatment,　including　high-temperature　sintering　and　mechanical　shearing　and　blowing,　was　performed　to　evidently　improve　the　electron　translocation　and　field　emission　current　density　of　CNTF　Excellent　emission　prosperities　were　exhibited:　stable　current　density,　distributed　uniformity　emitters　and　long　lifetime.　The　treatment　of　high-temperature　sintering　and　mechanical　shearing　and　blowing,　may　be　an　important　prerequisite　for　future　field　emission　display.　(C)　2007　Elsevier　Ltd.　All　rights　reserved.
