Area of Science:

  • Materials Science
  • Nanotechnology
  • Polymer Science

Background:

  • Understanding the interphase region is crucial for optimizing the properties of polymer nanocomposites.
  • Graphene-based nanofillers, such as graphene nanoplatelets (GNPs) and graphene oxide (GO), are widely investigated for enhancing epoxy matrices.
  • Characterizing the interface between nanofillers and polymer matrices is essential for predicting material performance.

Purpose of the Study:

  • To quantitatively investigate the interphase and interface characteristics of graphene nanoplatelets (GNPs)/epoxy and graphene oxide (GO)/epoxy composites.
  • To determine the thickness and density variations within the interphase regions.
  • To correlate experimental findings with existing theories on interphase behavior.

Main Methods:

  • Utilizing scanning transmission electron microscopy (STEM) for high-resolution imaging.
  • Employing electron energy-loss spectroscopy (EELS) to analyze the electronic structure and chemical composition of the interphase.
  • Performing spectral acquisitions along lines traversing the interface to map variations.

Main Results:

  • Clearly identified interphase regions in both GNPs/epoxy and GO/epoxy systems through plasmon peak discrepancies in EELS spectra.
  • Measured interphase thicknesses of approximately 13 nm for GNPs/epoxy and 12.5 nm for GO/epoxy.
  • Observed a density increase of 2.89% in the GNPs/epoxy interphase and a decrease of 1.37% in the GO/epoxy interphase compared to the neat epoxy matrix.

Conclusions:

  • The study provides quantitative insights into the interphase structure of graphene-epoxy composites.
  • The measured interphase thicknesses align with the transition layer theory, suggesting a gradual variation in material properties.
  • These findings can guide the functionalization of nanofillers to enhance the overall properties of carbon-based polymer composites.
