Transparent　conducting　films　based　on　solution-synthesized　copper　nanowires　(Cu　NWs)　are　considered　to　be　an　attractive　alternative　to　indium　tin　oxide　(ITO)　due　to　the　relative　abundance　of　Cu　and　the　low　cost　of　solution-phase　NW　coating　processes.　Moreover,　transparent　electrodes　tend　to　be　flexible.　This　makes　Cu　NWs　more　attractive　because　ITO　is　brittle　and　can　not　meet　the　requirements　of　flexibility.　For　Cu　NWs,　aspect　ratio　is　an　important　property.　Cu　NWs　can　be　directly　prepared　by　chemical　reduction　with　various　reducing　agents　and　suitable　capping　agents.　In　general,　the　selectivity　of　the　capping　agent　is　very　important　for　the　formation　of　one-dimensional　nanostructures　because　it　plays　a　major　role　in　the　thermodynamic　regulations　and　growth　kinetics　that　influence　the　geometry　and　morphology　of　the　crystal　facets.　Therefore,　different　aspect　ratios　are　formed.　Conductivity　is　the　most　important　property　for　transparent　electrodes.　Organic　pickling,　annealing　and　glare　pulses　have　a　certain　improvement　in　conductivity.　Meanwhile,　it　is　also　essential　to　increase　the　oxidation　resistance　of　the　transparent　electrode.　The　reduction　of　graphene　oxide　(r-GO),　the　coating　of　metal　and　polymer　improve　the　oxidation　resistance　of　the　transparent　electrode　to　varying　degrees.　This　paper　reviews　the　effect　of　different　capping　agents　on　the　aspect　ratio　of　NWs,　and　the　effects　of　different　post-treatments　on　oxidation　resistance　and　conductivity　of　transparent　electrodes.
