TU Delft thinks price graphene factor thousand to decrease




Researchers at TU Delft think a way found to fabricate graphene for a price that is a thousand times lower than what is currently the practice. The method works with a copper layer as a catalyst to produce methane from a layer of graphene.

The method to make graphene is described in the thesis of Shou-En Zhu. He will soon receive his PhD at TU Delft and have seen that it is possible to effectively produce graphene with only copper and methane, hydrogen and argon as feedstocks. At a temperature of 1000 degrees, the gas mixture passed over the copper. Subsequently, the buyer causes the hydrogen atoms are ‘stripped’ from the methane, leaving only carbon remains, which then as a single layer on the copper “sticks”.

According to Zhu, the use of this method ensures that a factor of a thousand graphene can be cheaper. For example, a piece of graphene with the size of its conventional production costs 1,000 euros, while Zhu here for only 1 euro needs. The scientist graphene can produce significantly faster than usual now. Tests show that the quality is in order: Zhu synthetic graphene has been deployed in a number of applications, such as a pressure sensor.

Much research is being done on graphene because it is expected to be used for many products. For example, graphene can very well conduct heat and electricity, while there is only one atomic layer is required for. That makes flexible electronics possible.
