SUMMARY

This discussion focuses on the investigation of graphene nanoplatelet dispersion in epoxy resin using X-ray diffraction (XRD). The user conducted XRD analysis on a sample containing 1.0 wt% graphene-epoxy and neat epoxy, noting sharp peaks that suggest the presence of undispersed graphene oligomers. Another participant clarified that the sharp peak may indicate graphite presence, while a broad shoulder could represent the amorphous nature of the sample. These insights are crucial for understanding the dispersion quality of graphene in epoxy composites.

PREREQUISITES
  • Understanding of X-ray diffraction (XRD) techniques
  • Knowledge of graphene nanoplatelets and their properties
  • Familiarity with epoxy resin formulations
  • Basic concepts of plasma functionalization processes
NEXT STEPS
  • Research X-ray diffraction analysis techniques for polymer composites
  • Study the effects of plasma functionalization on graphene dispersion
  • Explore methods to quantify dispersion quality in nanocomposites
  • Investigate the relationship between sharp peaks in XRD and material composition
USEFUL FOR

Researchers, materials scientists, and engineers involved in composite materials development, particularly those focusing on graphene-epoxy systems and XRD analysis.

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.
