What is Single-Layer Graphene Oxide Powder?

Graphene oxide powder is formed by creating a monolayer of graphene oxide. Its folded structure makes the powder more porous and reduces the number of micro- and mesopores between sheets, decreasing the likelihood of graphene sheet stacking and ultimately improving dispersibility and wettability.

Traditional multi-layer graphene powder is obtained by liquid exfoliation of graphite, oxidation of pyrolytic graphite, or biomass conversion. Properties such as density, specific surface area, oxygen content, and defect degree of graphene oxide powder can be adjusted by controlling the preparation process to meet the requirements of various applications.

Superconducting Yet Super-Flexible Graphene Films

Graphene, the most studied two-dimensional (2D) carbon allotrope, consists of a single simple layer of conjugated atoms arranged in a honeycomb lattice. Low atomic mass, strong bonds, simple crystal structure, and low anharmonicity give graphene outstanding thermal conductivity of ≈5300 W·m⁻¹·K⁻¹. Meanwhile, its single-layer structure imparts potential flexibility. These unique properties make graphene promising as an alternative building block for fabricating ultra-high-conductivity yet ultra-flexible macroscopic materials.

Defect-free and large graphene blocks (100–200 μm) give graphene films higher thermal conductivity than conventional polyimide carbonized films. Additionally, large micro-folds make the film ultra-flexible.
