The Fourier transformed
infrared spectroscopy (FTIR) test of SEBS, MA-g-SEBS,
and their nanocomposites were conducted on a Perkin-Elmer 1000 FTIR
spectrometer. Raman spectra were measured on a ThermoFisher/DXR. The
X-ray diffraction (XRD) measurement was carried out on a Rigaku D/Max
2550 (Cu Kα, λ = 1.5418 Å) with a 2θ scan configuration
in the range of 5°–40°. X-ray photoelectron spectroscopy
(XPS) experiment was performed on a Shimadzu-Kratos (AXIS Ultra).
Typical tapping-mode atomic force microscope (AFM) measurements were
taken on a SIINT NanoNavi E-Sweep, with which not only the single-layer
GO platelets were observed but also the microscopic surface roughness
of the hybrid films was measured. Macroscopic surface roughness of
the films was obtained from a Bruker DektakXT Surface Profiler. The
sandwich structure of the LBL assembled films was observed using a
JEOL JSM-7401F scanning electron microscope at an acceleration voltage
of 5 kV, and all the samples were fractured after immersion in liquid
nitrogen for a few minutes. Dynamic mechanical analysis (DMA) was
carried out using a NETZSCH DMA 242 C/1/G instrument. The tensile
tests were conducted on a MTS Criterion Model 43 universal testing
machine, with a crosshead speed of 500 mm/min at the temperature of
25 °C.

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.
