A photo‐annealing approach was developed for building functional polymer layers on paper. In their Communication on page 4465 ff., Y. Wang and co‐workers show that conducting polyaniline with the ability to undergo photothermal conversion can be annealed by near‐infrared light. The porous structure is retained in the annealed polymer but it becomes insulating and hydrophobic. The asymmetric paper functions as a “water diode” and selective photo‐annealing produces patterned conductive arrays.
