This spectra is related to a ceramic/CNT layer that created using plasma electrolytic process. Functionalized MWCNT is used for this purpose.
Could we conclude the incorporation of MWCNT in the coating layer?
The peaks correspond to 1386 and 1635 cm-1 are related to the f-MWCNTs unless your ceramic doesn't possess these two peaks. It is better to do a control Raman spectra before drawing the conclusion.
I would definitely run a uncoated ceramic (TiO2?) spectrum as well as one with the MW-CNT's on another substrate. The lack of a peak at ~2700 may indicate a lack of deposition or a decomposition during the process. Did you do a baseline correction on this spectrum?
Hi Mosen,
All the comments above are right. You should do 2 references (one the ceramic w/o CNT) to remove the Features that Comes from it, and a pure CNT without the ceramic. If there is a shift or Change of the Feature between the CNT and CNT/ceramic maybe you can conclude something about the interaction of CNT with ceramic, otherwise is probably only a phisical mixture.

Dear Sirs,
Thank you for your responces. I will try to do additional experiments according to your valuable comments.
Dear Dr. Sabouri, I guess that the attached articles are related with the topic you are studying.
Kind regards,
Faiz
Dear Mohsen,
I have explained the Raman spectra of MWCNTs in almost all of my articles. The D band at 1343-1350 cm-1 represents the defects and disorders in the sp2 C-C network of CNTs while G band at 1570-1580 cm-1 is representative of pristine arrangement of carbon atoms in graphitic structure of CNTs, in other terms metallicity or degree of crystallinity of MWCNTs. The chatacteristic ratio of these two bands ID/IG is reperesentative of quality of CNTs after several procesing stages i.e. dispersion, functionalization, consolidation etc. you can get more info from my articles.
Best wishes,
Khurram
