Since graphene nanostrips have extremely high intralayer Young's modulus and ultralow interlayer shear modulus, we propose a multibeam shear model (MBSM) that neglects the intralayer stretch but accounts for the interlayer shear.
In particular, mechanical tests have been carried out both in air and immersing the specimens in phosphate buffered saline (PBS) solution at 37 °C, in order to evaluate the elastic modulus and the interlayer adhesion strength.
The mechanical properties, such as the Young's modulus, the interlayer shear modulus and the ultimate tensile strength, of bilayer graphene sheets (GS) coupled by sp3 bonding are investigated by molecular dynamics simulations.
Benefiting from the high interlayer shear modulus and strength, the assembling of the wrinkled graphene sheet can construct a graphene membrane with tensile strength up to 12.57 GPa.
Experimental arrays were then constructed to investigate the effect of relative percentage volume fraction, substrate bias and interlayer wavelength against the Young's modulus, tensile strength, ultimate tensile strength and other mechanical properties of the foils.
The shear modulus and mass density of the FGM interlayer are assumed to vary continuously between those of the two coaxial dissimilar homogeneous elastic cylinders.
The results show significant enhancements in fracture strength (~ 200%) and tensile modulus (20 100%) are attained through synergistic effect of ternary graphene oxide structures and interlayer interaction between PVA, graphene oxide and zirconium diboride particles.
It accurately quantifies deterioration of tensile modulus and strength at the expense of improving interlayer adhesion with increasing oxidation of varying chemical compositions.
The interlayer distance and interlayer bond energy is 3.34 Å and 2 eV/nm2, respectively.
Layered inorganic compounds have interesting physical/chemical properties, such as tunable interlayer spacing and interlayer composition, and can be readily functionalized via intercalation to produce specific properties [1].
