Abstract 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 response to ammonium gas. Complete photo‐annealing preserves the porous structure but changes the wettability of the polyaniline‐nanofiber film.
