Popis: The present paper shows the template-assisted electrodeposition of highly ordered macroporous zinc films in the ionic liquid 1-butyl-1-methylpyrrolidinium trifluoromethylsulfonate ([Py1,4]TfO). Polystyrene (PS) spheres were employed as templates, and zinc films were electrodeposited within the interstitial voids of the template. The results show that well-ordered two- or three-dimensional macroporous zinc films can easily be made. The obtained macroporous films showed diffractive light when illuminated with white light. The contact angle measurements revealed that the wettability of the employed ionic liquid on PS templates is much better than the one of aqueous solutions, leading to better infiltration into the interstitial voids of the PS spheres. Macroporous zinc is potentially interesting as host material for lithium ion batteries.
