High-quality monolayer graphene films for research and industrial applications — customizable, reproducible, and rigorously characterized.
What is Graphene?
Remarkable two-dimensional carbon material consisting of a single layer of atoms arranged in a honeycomb lattice. Each atom bonds to three neighbors, forming a structure that is both elegant and incredibly stable. Derived from graphite — the same substance found in pencil lead — sheets represent the thinnest, strongest, and most conductive material ever discovered.
Extraordinary Properties
- Strength: ~200 times stronger than steel, despite being only one atom thick.
- Lightweight: Sheet large enough to cover a football field would weigh less than a gram.
- Flexibility: can bend and stretch without breaking, making it ideal for wearable and flexible electronics.
- Conductivity: It conducts electricity more efficiently than copper and dissipates heat better than most known materials.
Because of this unique blend of characteristics, it is often described as a “wonder material.” It holds promise for revolutionizing biosensors, nanotechnology, energy storage, transparent electronics, and medical devices.
Product Overview
Our monolayer graphene films are synthesized using advanced Chemical Vapor Deposition (CVD) techniques to ensure exceptional uniformity, purity, and electrical performance. Each layer exhibits >97% optical transparency, >95% surface coverage, and high carrier mobility, making it ideal for electronics, flexible devices, biosensors, and advanced materials research.
We supply graphene films on multiple substrates, including:
- Copper (Cu) foil
- PET (polyethylene terephthalate) flexible films
- Si/SiO₂ wafers (90 nm oxide)
Custom sizes, doping, and PMMA protective coatings are available to suit specific R&D or production requirements.
