| Abstract Scope |
This study investigated epoxy resin composites reinforced with varying concentrations of graphene oxide (GO) (0.1%, 0.2%, and 0.5%) to assess chemical interactions using Fourier Transform Infrared (FTIR) Spectroscopy. Analyses, performed from 4000 to 400 cm⁻¹, identified characteristic bands for hydroxyl, carbonyl, aromatic, and epoxy groups. An increase in the ~3400 cm⁻¹ band intensity with higher GO content suggested enhanced hydrogen bonding. Similarly, the ~1720 cm⁻¹ band, corresponding to carbonyl groups, intensified with increasing GO concentration, indicating greater matrix functionalization. Conversely, a reduction in the ~1050 cm⁻¹ band intensity pointed to reactions between epoxy and GO's oxygenated groups, highlighting significant chemical interactions. These FTIR results confirm the technique's effectiveness in evaluating chemical compatibility between composite components. We conclude that a 0.2% GO content achieves an optimal balance between functionalization and matrix stability. |
