Carbon fiber reinforced polymers (CFRP) have been increasingly used in aircraft structures. However, their relatively low electrical conductivity leads to the vulnerability to lightning strike. Herein, the carbon nanotube buckypaper-based coatings composed of conductive buckypaper and insulating adhesives were developed to protect the CFRP laminates. Their influence on the lightning strike protection...
We systematically investigated the in-plane biaxial compression behavior of the monolayer poly (methyl methacrylate) (PMMA)/graphene/PMMA system by in situ Raman spectroscopy. The shifts of Raman G-band peak position exhibited three-stage features with increasing compressive strain, including elastic deformation, local Euler-buckling and continuous compression. Our results demonstrated that the mechanical...
Graphene oxide (GO) was added to nickel ferrite (NiFe 2 O 4 ) to yield GO-doped NiFe 2 O 4 (GO–NiFe 2 O 4 ). The as-prepared GO–NiFe 2 O 4 samples were characterized by powder X-ray diffraction, Fourier-transform infrared spectroscopy, Raman spectroscopy, transmission electron microscopy, scanning electronic microscopy, X-ray photoelectron...
In recent years, large fluctuations have been reported for measurements of the hydrogen storage of carbon materials using a Sieverts apparatus. To investigate this problem, helium gas adsorption was selected for comparison with the adsorption of hydrogen, and the results show that hydrogen but not helium was adsorbed onto the wall of the sample cell at ambient temperature. The adsorption capacity...
