Does anyone do the reaserch about graphitic carbon materials,if you want to make a beatiful TEM image ,what you can do for a thin and good tem-sample?I want to make my sample thiner and like one layer graphene. I have tried to exfoliation it by NMP , even adding NaOH,SDBS,SDS . How can I obtain a good TEM image.
What kind of samples do you have? Is it a monolith graphite? What is a sample preparation process?
I prepare my sample by carbonized polymer . But my sample like amphours carbon.
Amphours? May be did you mean "amorphous"? :)
If you make the conventional ultrathin sections by an ultramicrotomy they have a thickness nearly 50 nm. It is 50+ times more than single layer graphene. It is fundamentally impossible to have a thickness like graphene for amorphous carbon, but you can use the ion etching technique for decreasing of thickness.
