Highly　stable　and　patterned　silver　nanowire　(AgNW)　networks　are　essential　and　challenging　for　flexible　or　wearable　electronics.　In　this　work,　TiO2　coatings　by　atomic　layer　deposition　(ALD)　technique　were　introduced　for　the　fabrication　of　highly　stable　and　patterned　AgNW/TiO2　composites　for　flexible　transparent　conductive　electrodes　(TCEs).　It　was　found　that　TiO2　coating　could　not　only　enhance　the　adhesion　of　AgNWs　to　the　substrate,　but　also　improve　the　flexibility　of　AgNW　networks.　This　phenomenon　was　owed　to　the　stability　enhancement　by　the　three-dimensional　conformal　deposition　of　TiO2　coatings.　What’s　more,　the　thermal　and　oxidation　stabilities　of　AgNW　networks　could　be　greatly　improved　because　of　the　barrier　performance　of　TiO2　coating　layer.　Based　on　the　stability　enhancement　by　TiO2　coatings,　a　novelty　patterning　method　of　the　AgNW　networks　was　implemented　by　cooperating　with　photolithography　and　ultrasonic　concussion　process.　AgNW　networks　with　the　strip　width　of　200 μm　were　well　patterned　without　defects.　Finally,　highly　stable　and　patterned　AgNW/TiO2　composites　were　applied　as　flexible　TCEs　for　alternating　current　electroluminescent　(ACEL)　devices.　The　whole　ACEL　device　showed　a　high　transparency　of　around　40%,　and　the　flexibility　and　the　lifetime　of　ACEL　devices　were　correspondingly　improved　owe　to　the　enhancement　by　TiO2　coatings.　These　results　indicated　the　prospects　of　the　AgNW/TiO2　composites　on　the　applications　to　flexible　or　wearable　electronics.　Graphical　abstract:　TiO2　coatings　by　atomic　layer　deposition　(ALD)　technique　were　introduced　for　the　fabrication　of　highly　stable　and　patterned　AgNW/TiO2　composites　for　flexible　transparent　conductive　electrodes　(TCEs).　[Figure　not　available:　see　fulltext.].　©　2023,　The　Author(s),　under　exclusive　licence　to　Springer　Science+Business　Media,　LLC,　part　of　Springer　Nature.
