NOVELTY - Preparing and testing performance of graphene-graphene nanoribbons involve using experimental materials and instruments, determining the concentration of graphene oxide (GO) and graphene oxide nanoribbon (GONR) solutions by gravity method, and taking one milliliter of the graphene oxide solution and dropping it on the weighed glass slide in mg/mL, and testing its weight after drying in 80 degrees C oven. The difference between the two is the GO (or GONR) content per milliliter of GO (or GONR) solution in ratio 1: 1, extracted the corresponding volume of solution into the mold, stir and mixed. The GO-GONR solution is mixed in a cold well of a freeze dryer for 24 hours, and then evacuated to start freeze-drying. USE - Method for preparing and testing performance of graphene-graphene nanoribbons. ADVANTAGE - The method enables to prepare and test performance of graphene-graphene nanoribbons that improves the strength of graphene sponges.
