Graphene sheets production method

A Spanish university has developed a new method to produce graphene, one of the most promising materials developed during last years. Due to its physical properties graphene has a wide range of applications: semiconductors, electronics, battery energy or composite industry.
The new method consists in rubbing the powder of a material selected from graphene, boron nitride, molybdenum disulfide or tungsten disulfide between two substrates.
A sheet of a few strips is formed on at least one of the substrates. The results are very promising as sheets of several strips with 1 to 5 layers of graphene have been obtained. The strips are of a high quality as they don't present any holes in their atomic structure. The new method is cheaper and more environmentally friendly than others because it avoids the use of dissolvents.
Several experiments have been carried out to demonstrate the performance of the method under different conditions: pressure applied in the rubbing process, rubbing time, use of different substrates, etc.
The university is looking for industrial partners from the electronic components industry or manufacturers of this type of highly innovative materials willing to licence the technology.
