Durch Belichtung können funktionelle Polymerschichten auf Papier aufgebaut werden. In ihrer Zuschrift auf S. 4554 ff. zeigen Y. Wang und Mitarbeiter, dass die poröse Struktur von leitfähigem Polyanilin bei der photothermischen Behandlung mit Nahinfrarotlicht erhalten bleibt, während das Polymer isolierend und hydrophob wird. Die unsymmetrischen Papiere wirken als “Wasserdiode”, und eine selektive...
A straightforward photo‐annealing approach was developed for building functional polymer layers on paper. Conducting polyaniline with the ability for photothermal conversion can be readily annealed by near‐infrared light. The annealed polymers become both insulating and hydrophobic. Selective photo‐annealing produces a functional layer with patterned conductive arrays. This material exhibits real‐time...
