X-Ray Photoelectron Spectra (XPS) XPS was used to further study the formation of AgNPs on the surface of nanocomposites, as shown XPS was used to further study the formation of AgNPs on the surface of nanocomposites, as in Figure 3. This is because XPS is a powerful technique used to investigate the interaction between shown in Figure 3. This is because XPS is a powerful technique used to investigate the interaction silver, RGO, and polymer nanocomposites. Detailed scans of Ag3d and C1s are plotted in Figure 3a–f. between silver, RGO, and polymer nanocomposites. Detailed scans of Ag3d and C1s are plotted in The C1s XPS spectra of GO (i.e., Figure 3a) displays the typical peaks at 282.0 eV for C–C, 284.3 eV for Figure 3a–f. The C1s XPS spectra of GO (i.e., Figure 3a) displays the typical peaks at 282.0 eV for C– C–O, and 285.9 eV for C (epoxy/alkoxy). The peaks with a low intensity correspond to the oxygenated C, 284.3 eV for C–O, and 285.9 eV for C (epoxy/alkoxy). The peaks with a low intensity correspond functionalities shown in Figure 3b–d, confirming the successful reduction of GO into RGO within to the oxygenated functionalities shown in Figure 3b–d, confirming the successful reduction of GO the PS-PMMA matrix in the presence of hydrazine hydrate via the MWI method. Moreover, from into RGO within the PS-PMMA matrix in the presence of hydrazine hydrate via the MWI method. Figure 3e,f, the peaks observed in the energy region of the Ag 3d transition are symmetric, with Moreover, from Figure 3e,f, the peaks observed in the energy region of the Ag 3d transition are two characteristic binding energy peaks for Ag3d, i.e., for the metallic Ag at 374.2 and 368.2 eV symmetric, with two characteristic binding energy peaks for Ag3d, i.e., for the metallic Ag at 374.2 corresponding to doublets of Ag3d3/2 and Ag3d5/2 [33/25], respectiv5/2ely. This indicates the metallic nature and 368.2 eV corresponding to doublets of Ag3d and Ag3d [35], respectively. This indicates the of silver and no evidence for the existence of Ag+ is obtained. Therefore, the XPS study confirmed the metallic nature of silver and no evidence for the existence of Ag+ is obtained. Therefore, the XPS success of metallic AgNPs formation within the RGOPS-PMMA/Ag nanocomposites. As can be seen in study confirmed the success of metallic AgNPs formation within the RGOPS-PMMA/Ag Figure 3f, the XPS spectra of R-(GO-(PSPMMA))/AgNPs show the splitting of the 3d duplet at 6.00 eV. nanocomposites. As can be seen in Figure 3f, the XPS spectra of R-(GO-(PSPMMA))/AgNPs show the However, the in situ-prepared nanocomposite recorded splitting of the 3d doublet at 6.02 eV. The slight splitting of the 3d duplet at 6.00 eV. However, the in situ-prepared nanocomposite recorded splitting negative shift of about −0.02 eV suggests that there was a stronger interaction between the materials of the 3d doublet at 6.02 eV. The slight negative shift of about - 0.02 eV suggests that there was a due to the MWI-enhanced electron transfer from the electron-rich RGO/PS-PMMA composites to stronger interaction between the materials due to the MWI-enhanced electron transfer from the AgNPs [42]. electron-rich RGO/PS-PMMA composites to AgNPs [42].PDF Image | Microwave Irradiation Synthesis Silver Nanoparticle
