Welcome to G-World!

Graphene is 2D carbon nanomaterial with the thickness of single C atom.

Structurally, graphene is the thinnest nanomaterial in the universe.

Electronically, graphene presents high mobility more that X100 of Si and high current density more than X1000 of Cu.

Thermally, graphene is the best thermal conductor in the universe.

Mechanically, graphene is stronger more that X200 compared with steel, flexible, foldable and even stretchable.

Optically, graphene is highly transparent. Single graphene layer gains 2.3% of optical absorption at 550 nm.

Forget about Nobel Prize on Graphene!

In 2010, professor Andre Geim and Konstantin Novoselov from Manchester University won Nobel Prize in Physics.

What FNML does research on graphene?

FNML (Functional Nanomaterials Laboratory) in KNUT is doing several researches on graphene and other 2D nanomaterials.

1. Nanomaterials Tool --------------------------------------

1.1. 2D Graphene : Soluble

< Typical GO (graphene oxide) solution (1 mg in 10 mL of water) : should be prepared just before use and should be soluble in water with brief sonication. If not, it is not GO. Threw it! >

< Typical rGO (chemically reduced graphene oxide) solution (1 mg in 10 mL of water) : should be optically clear. If not, there might be huge aggregation of as-reduced rGO plates. Threw it! >
