How does Enerage measure the concentration of graphene organic suspension?
The concentration is measured by the ultraviolet/visible spectroscopy. The value of solid content is derived from comparing the absorbency of graphene organic suspension S-ON20 to the absorbency of sample which the solid content is known.
What is the solid content of graphene organic suspension?
The solid content of graphene organic suspension S-ON20 is around 200ppm, which is 40 mg graphene suspended in 200ml solvent.
Which kind of solvent can be homogeneously mixed with graphene organic suspension S-ON20?
N-Methyl-2-Pyrrolidone (NMP) is used as solvent to produce graphene organic suspension S-ON20. NMP is miscible in water, ethanol, acetone, ethyl acetate, chloroform, benzene etc.
What temperature should be reached to remove the solvent in graphene organic suspension S-ON20?
N-Methyl-2-Pyrrolidone (NMP) is used as solvent to produce graphene organic suspension S-ON20. The boiling temperature of NMP is 203℃. The appropriate heating temperature is according to the substrate of cast film and the mixed materials. Based on our experience, most NMP is able to be removed by soft-baking at 100℃ for 30 minutes for spin coated film.
What kind of organic solvent is applied in graphene organic suspension S-ON20?
N-Methyl-2-Pyrrolidone (NMP) is used as solvent to produce graphene organic suspension S-ON20. The solvent is commonly and widely applied in electronic, painting, chemical and pharmaceutical field because of its polar property, low freezing point and good chemical stability.
