Nicolet ir 200 ft ir spectrometer

Morphologies of the G/PANI nanocomposites were characterized via field-emission scanning electron microscopy (FE-SEM, JSM-6500 F, JEOL Ltd., Akishima-shi, Japan). Thermal properties were characterized using a thermogravimetric analysis (TGA, Q50, TA Instruments, New Castle, DE, USA). Functional group of the nanocomposites was determined using a Nicolet IR 200 FTIR spectrometer (Thermo Scientific, Waltham, MA, USA) and the I_D and I_G values of the graphene were determined using a Raman (DXR; Thermo Scientific, Waltham, MA, USA). The charge/discharge and CV of the G/PANI electrode were performed by using a battery tester (Won A Tech, WBCS 3000, Seoul, Korea). EIS was measured using Bio Logic Science Instruments (Claix, France).

Morphologies of the RGO-24 and RCMGO-24 were characterized via field emission scanning electron microscopy (FE-SEM, JSM-6500 F, JEOL, Akishima-shi, Japan). Thermal properties were characterized using thermal gravimetric analysis (TGA, Q50, TA, New Castle, DE, USA). The electrical conductivity of the graphene pellet was determined by the four-point probe method (CMT-10 MP, AIT). The functional groups of the RGO were determined by FT-IR on a Nicolet IR 200 FT-IR spectrometer (Thermo Scientific, Waltham, MA, USA) in transmission mode, and Raman (Thermo scientific, DXR) with 633-nm wavelength incident laser light was used to characterize the degree of reduction on the graphene sheets. X-ray diffraction (XRD) analyses were performed on a high-power X-ray diffractometer (Rigaku, Shibuya-ku, Japan) at 2θ range from 2° to 40°. X-ray photoelectron spectroscopy (XPS) was taken on a Thermo Fisher instrument using Al Kα radiation (energy range 200 to 3 keV). Galvanostatic charge/discharge and CV were characterized using a Won A Tech (WBCS 3000) battery tester. EIS was measured using BioLogic Science Instruments (Claix, France).

The FTIR spectra were plotted to confirm the functional groups utilizing a Nicolet IR 200 FT-IR spectrometer (Thermo Fisher Scientific). XPS (Thermo Fisher) measurements were completed by means of monochromatic AlKα radiation (hʋ= 1486.6 eV).
