The　CuO　nanowires/single-walled　carbon　nanotubes　(SWCNTs)　composite　coatings　were　fabricated　via　drop-coating　of　SWCNTs　on　the　Cu　(OH)2　nanowires　vertically　grown　on　Cu　substrate　in　hydrothermal　method　followed　by　sintering　in　air　at　200℃　for　2　h.　The　microstructures　and　field　emission　characteristics　of　the　CuO　nanowires/SWCNTs　coatings　were　characterized　with　X-ray　diffraction,　scanning　electron　microscopy.　The　SWCNTs　bundles　were　found　to　ho-mogenously　distribute　in　mesh-shaped　patches,　on　almost　half　of　the　surface　areas　of　the　CuO　nanowire-array　films.　The　results　show　that　the　CuO　nanowires/SWCNTs　composite　coating　is　a　promising　field　emission　material　because　of　its　favorable　field　emission　properties.　For　instance,　it　has　a　low　on-set　field　of　about　0.8　V/μm,　a　high　field　enhancement　fac-tor　of　12084,　and　good　emission　stability,　possibly　because　of　good　thermal　conductivity　of　CuO　nano-wires.　Besides,　its　technical　strengths　include　easy　fabrication　at　a　low　temperature　and　low　fabrication　cost.
