In　recent　years,　the　demand　for　transparent　substrates　(e.g.　windows,　mirrors　and　photovoltaic　glass)　with　anti-fogging　performances　has　increased,　while　conventional　anti-fogging　coatings,　like　single-component　organic　coatings　(PVA,　PAA,　PAAm),　show　poor　stability　and　cannot　maintain　their　performance　stably　under　harsh　environments.　In　this　work,　KH570@TiO2　plays　the　role　of　a　bottom　layer　(KT　coating)　to　increase　roughness　and　binding,　where　the　hydrolysis　of　KH570　anchors　the　substrate　and　provides　active　sites　for　the　binding　of　the　top　coating,　and　the　addition　of　the　TiO2　enhances　UV　shielding　properties.　A　composite　PVA-AAm-POSS-NH2　gel　(PAP　coating)　served　as　the　top　layer,　which　contains　a　large　number　of　hydrophilic　groups　and　thus　endow　the　composite　coating　with　satisfactory　anti-fogging　performance.　The　strong　bonding　force　provided　by　the　KT　coating　and　the　tight　physical　entanglement　of　the　PAP　coating　endow　the　double-layer　coating　(PAPKT　coating)　stable　anti-fogging　performance　(60　times　of　tape　peeling　test,　100　times　of　sandpaper　friction　test,　and　sand-punching　test),　and　48　s　icing　delay　performance.　The　multi-performances　make　this　work　great　potential　in　automotive　glass　as　well　as　building　facades　to　cope　with　complex　situations.　©　2024
