Hello I was trying to find difference between solvent exposure on graphene. I added a picture here. Is my interpretation ok about the bonding? though all the curve looks like same except the transmittance scale. have any suggestion to get more different curve as I am exposing to different solvent so there should be some difference between curves. I am just exposing the graphene layer with the solvent vapor and measuring the ATR. any more suggestion about the curve and bonding will be appreciated. Thanks!!!
Does the IPA mean isopropanol? If so, why there is a obvious adsorption peak of C=O in IPA/GN spectrum? I don't know your experimental details, so I can't give understanding.
Yes isopropanol. I am also puzzled about that. I did that several time but same result came. I used to take background first or bare graphene layer then expose it to the vapour or solvents and measure the ATR again. That's how I do it. The thing is I took background only once which background is used for every sample. This time I am thinking to take background every time before exposing.
Have you done the IPA testing? Maybe IPA is impure. Additionally, testing on transmitting mode may be helpful to find out the problems.
Can you please tell me about how to do that in transmitting mode? Mr zhang. Thanks
Even I already solved the ipa's co band. It is not there but still acetone is giving some wide band in OH region. It may be from the air?! What you guys think? Let me know please
