FTIR Analysis of JS-C12 and JS@GO: Evidence of Successful Reaction with GO

As shown in Figure 1, the absorption peak at 3200-3600 cm-1 is attributed to the O-H bond vibration in the hydroxyl group. In the JS-C12 and JS@GO samples, the absorption peaks in the region of 2850-2960 cm-1 are caused by the symmetric and asymmetric stretching vibrations of the C-H bond. The absorption peak at 1000-1200 cm-1 is attributed to the stretching vibration peak of Si-O-Si, which was not observed in the infrared spectrum of the GO sample. Additionally, the absorption peak of COOH at 1700-1750 cm-1 disappeared in the JS@GO sample, and the absorption peak of CO-NH appeared near 1635 cm-1, indicating that JS-C12 has reacted with GO to form JS@GO.
