Dear Friends, currently I am facing a problem regarding the XRD of thermoplastic polyurethane (TPU)-reduced graphene oxide (RGO) nanocomposite. I have loaded 0.2 wt% reduced graphene oxide in TPU matrix by in-situ polymerization and during XRD I am getting two peaks one at 7 degrees and another at 21 degrees. The peak at 21 degrees is expected in polyurethane matrix but the peak at 7 degrees is not expected but it is coming. I have repeated the experiment thrice but the same result is coming. So, I want your help to understand why this is coming?????// If anyone can help me I will be very grateful to him or her.
Thank you
Graphene oxide exhibits one peak at 7 to 10 degree, Please be sure it is GO or RGO. please follow the some papers ;
