The　transparent　electrodes,assembled　on　glass　substrate　by　spin-coating　of　the　ultra-long　silver　nanowires　(Ag-NWs)　synthesized　via　chemical　route,were　annealed　and　compressed.The　effect　of　the　annealing　temperature　and　compression　pressure　on　the　microstructures　and　properties　of　the　Ag-NWs　coatings　was　investigated　with　scanning　electron　microscopy,energy　dispersive　spectroscopy,high　resolution　transmission　electron　microscopy,and　ultraviolet　spectroscopy.The　results　show　that　the　annealing　and　compression　strongly　affect　the　microstructures,properties　and　contents　of　the　electrode.For　example,annealed　at　200℃　and　compressed　at　5　MPa,the　coating＇s　sheet　resistance　rapidly　decreased　from　3200　to　17　Ω/□,possibly　because　of　removal　of　polyvinylpyrrolidone　from　surfaces　of　Ag-NWs　and　because　of　welding　and　electrical　connecting　of　Ag-NWs.The　annealing　and　compressing　of　the　substrate　of　Ag-NWs　coatings　explained　the　growth　of　well-defined　ZnO　nano-rod　arrays　and　reduction　of　the　on-set　emission　field　to　3.3　V/μm　at　a　current　density　of　1　μA　/cm2.　©　2016,　Science　Press.　All　right　reserved.
