Researchers in Germany and Sweden are saying that they can improve the quality of printed graphene inks using a technique called laser annealing. The method might be used to improve inks made from other 2D materials too, and so might become a standard procedure for producing such films. The graphene inks, which are transparent and highly conducting, could be used to make flexible electronics devices, including batteries and supercapacitors, transistors, solar cells and displays……
