主　　题：nanowire photothermal superhydrophobic de-icing defrosting 

摘      要：Ice and frost buildup continuously pose significant challenges to multiple *** a promising de-icing/defrosting alternative,designing photothermal coatings that leverage on the abundant sunlight source on the earth to facilitate ice/frost melting has attracted tremendous attention ***,previous designs suffered from either localized surface heating owing to the limited thermal conductivity or unsatisfied meltwater removal rate due to strong water/substrate ***,we developed a facile approach to fabricate surfaces that combine photothermal,heat-conducting,and superhydrophobic properties into one to achieve efficient de-icing and *** copper nanowire assemblies,such surfaces were fabricated via the simple template-assisted electrodeposition method,allowing us to tune the nanowire assembly geometry by adjusting the template dimensions and electrodeposition *** highly ordered copper nanowire assemblies facilitated efficient sunlight absorption and lateral heat spreading,resulting in a fast overall temperature rise to enable the thawing of ice and *** promoted by the excellent water repellency of the surface,the thawed ice and frost could be spontaneously and promptly *** this way,the all-in-one design enabled highly enhanced de-icing and defrosting performance compared to other nanostructured surfaces merely with superhydrophobicity,photothermal effect,or the combination of *** particular,the defrosting efficiency could approach∼100%,which was the highest compared to previous ***,our approach demonstrates a promising path toward designing highly effective artificial deicing/defrosting surfaces.
