Lawrence Livermore National Lab created a thixotropic ink based on graphene oxide nanosheets. It is suitable for various direct ink write printing technologies. The ink offers a stable dispersion of GO, high viscosity, good printability, and long shelf life. Freeze-dried and annealed patterns provide low electrical resistivity and high surface area. The ink is suitable for applications such as batteries, supercapacitors, electrocatalysis, etc.
