A graphene morphology is any of the structures related to, and formed from, single sheets of graphene. 'Graphene' is typically used to refer to the crystalline monolayer of the naturally occurring material graphite. Due to quantum confinement of electrons within the material at these low dimensions, small differences in graphene morphology can ...
Graphene (/ ˈ ɡ r æ f iː n /) [1] is ... A narrower definition, ... delivering tunable morphology and pore structure by controlling the evaporation of solvents ...
Graphene aerogel morphologies have also been demonstrated to be controllable through 3D printing methods. Graphene oxide ink composed of graphene oxide gelled in a viscous solution with the addition of silica to lower viscosity and enable printability of the graphene oxide ink. The ink is then extruded from a nozzle into isooctane, which ...
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 ...
Graphene oxide flakes in polymers display enhanced photo-conducting properties. [10] Graphene is normally hydrophobic and impermeable to all gases and liquids (vacuum-tight). However, when formed into graphene oxide-based capillary membrane, both liquid water and water vapor flow through as quickly as if the membrane was not present. [11]

In 2017, MIT researchers studied the possibility of using the gyroid shape to turn bi-dimensional materials, such as graphene, into a three-dimensional structural material with low density, yet high tensile strength. [19] Researchers from Cambridge University have shown the controlled chemical vapor deposition of sub–60 nm graphene gyroids ...
This "epitaxial graphene" consists of a single-atom-thick hexagonal lattice of sp 2-bonded carbon atoms, as in free-standing graphene. However, significant charge transfers from the substrate to the epitaxial graphene, and in some cases, the d-orbitals of the substrate atoms hybridize with the π orbitals of graphene, which significantly alters ...
