AI Thread Summary
The discussion focuses on the dispersion of graphene nanoplatelets in epoxy resin using plasma functionalization, with XRD analysis performed on a sample containing 1.0 wt% graphene-epoxy. The user is uncertain about interpreting the XRD results, particularly regarding sharp peaks that may indicate undispersed graphene oligomers. Another participant suggests that the sharp peaks could be related to graphite rather than graphene, while a broad shoulder may indicate the amorphous nature of the sample. The inquiry highlights the challenges faced by those new to XRD analysis in understanding the implications of their findings. Overall, the conversation emphasizes the need for clarity in interpreting XRD data in the context of material dispersion.

I'm trying to find out how well graphene nanoplatelets have dispersed into epoxy resin through plasma functionalisation. I've performed XRD upon a sample containing 1.0 wt% of graphene-epoxy and of neat epoxy. This is the first time I've used XRD so I'm unsure what conclusions can be drawn, I suspect that the sharp peaks are showing oligomers of undispersed graphene. Any help would be really appreciated.

willogrady, I think in your sample you have a sample with epoxy + graphene and graphite also. The sharp peak may be related to graphite, where the broad shoulder is related to the amorphous characteristic of your sample.
