Graphene is the strongest material ever tested, [7] [8] with an intrinsic tensile strength of 130 GPa (19,000,000 psi) (with representative engineering tensile strength ~50-60 GPa for stretching large-area freestanding graphene) and a Young's modulus (stiffness) close to 1 TPa (150,000,000 psi).
The electronic properties of graphene are significantly influenced by the supporting substrate. [59] [60] The Si(100)/H surface does not perturb graphene's electronic properties, whereas the interaction between it and the clean Si(100) surface changes its electronic states significantly. This effect results from the covalent bonding between C ...
Carbon nanotubes are the strongest and stiffest materials yet discovered in terms of tensile strength and elastic modulus respectively. This strength results from the covalent sp 2 bonds formed between the individual carbon atoms. In 2000, a multi-walled carbon nanotube was tested to have a tensile strength of 63 gigapascals (9,100,000 psi).

Graphene is the thinnest and strongest material recorded to date. It is also transparent, flexible and a good conductor for both heat and electricity.
Similarly, the compressive strength that describes the yield stress before plastic deformation under compression in graphene aerogels follows a power-law distribution: σ y /E s = (ρ/ρ s) n, where σ y is the compressive strength, ρ is the density of the graphene aerogel, E s is the modulus of graphene, ρ s is the density of graphene, and n ...
When filtered into graphene oxide paper, these composites exhibit increased stiffness and strength relative to unmodified graphene oxide paper. [14] Full hydrogenation from both sides of graphene sheet results in graphane, but partial hydrogenation leads to hydrogenated graphene. [15]
When the graphene was swapped out for polymers or metals, similar gains in strength were seen. [22] [23] A film of graphene soaked in solvent to make it swell and become malleable was overlaid on an underlying substrate "former". The solvent evaporated, leaving behind a layer of graphene that had taken on the shape of the underlying structure.
