| Sumario: | [EN] Understanding the surface interactions between graphite oxide and epoxy resin components is crucial to tailoring the performance of composite materials. To investigate the interactions of thermally expanded graphite oxide (TEGO) with the primary epoxy resin components, diamine hardener and epoxy resin prepolymer, surface-sensitive techniques, including Fourier transform infrared spectroscopy, Raman spectroscopy, and X-ray photoelectron spectroscopy, were employed. The reaction kinetics were studied over a temperature range from room temperature to 60 degrees C to assess thermal effects on interaction dynamics. The findings demonstrated a significant thermal dependence in the interaction between TEGO and the diamine hardener, whereas TEGOprepolymer interactions exhibited minimal variations, indicating weak interfacial bonding. This study offers valuable insights into TEGO/epoxy resin interactions, contributing to the advancement of high-performance composite materials. |
