Back Cover: A Photo-annealing Approach for Building Functional Polymer Layers on Paper (Angew. Chem. Int. Ed. 17/2014)
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.
