I make graphene by charring of polymer with controlled acid process with 70°C and further process like deacidification and purification by three wash with Double distilled water.
But I can't find my product with best quality, so can you suggest what should I do for quality and decrease size of graphene
For quality improvement, there is dire requirement of analytical tools. Eventually, confirmation from Raman and XPS will be required.
What methods have been used to check the quality?
Have u done a Raman analysis?
Thanks for your answer Mr.Omkar S. Kushwala and Mr. Chanaka Sandaruwan I will try with Raman analysis.
And can you suggest process Parameter of synthesise graphene?
Hi,
The quality of the graphene is highly dependent on the carbonization conditions. It is strongly dependent on the temperature and the rate of temperature rise as well as the carbonization time, the concentration of the acid and the degree of purification.
With my best regards

Quality in relation to what? What do you mean by ‘quality’? What is the intended application of your material and what is the deficiency, in your opinion?
Dear Viraj Nagariya I think that Alan F Rawle is absolutely right. You should be more specific about what you mean by "quality". Besides, some articles related to this topic are already available on RG, e.g.
Article Application of Taguchi Method to Improve Resistance Quality ...

To increase the quality of graphene you need to use a better synthesis method and correct characterization methods.
