The surface morphology of PSNS and PSNS@GO was observed by QUANTA FEG 450 Scanning Electron Microscope (SEM). The interlayer spacing of the sample was obtained by using the X-ray diffraction analyzer model Empyrean produced in the Netherlands. The change of organic functional groups was investigated using a Nexus Intelligent Fourier transformed infrared spectrometer from Thermo Nicolet Co., Ltd in a transmittance mode. The topological structures of dried PSNS@GO films were investigated by micro-CT (Xradia 510 Versa), the colormap of the image was in the range of 37 000 to 40 000 with 0.3 of opacity in volume rendering. The concentration of carbon atoms in different chemical environments in the sample was studied by ¹³C solid-state nuclear magnetic resonance (NMR) spectroscopy (Bruker, Advance, III400), it was carried out at 10 MHz and at a 25 kHz spinning speed. The structural changes of GO were detected by Raman spectrometer.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
