To evaluate the dispersion quality of graphene nanoparticles in an epoxy LY556 matrix, several complementary techniques are commonly used:

Microscopy methods
X-ray Diffraction (XRD)
Fourier Transform Infrared Spectroscopy (FTIR)
Thermal diffusivity mapping using non-contact Infrared (IR) thermography
Rheological measurements
Image analysis combined with elemental mapping
