Graphene-epoxy XRD

[willogrady]

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.
