A new method for making graphene: Interfacial Chemical Synthesis

A new breakthrough in making graphene has been created by Professor Aldo Zarbin and his team at the Universidade Federal do Paraná in Brazil. The Royal Society of Chemistry published this work, you can find out the details at this hyperlink. As well as being an entirely new method for making graphene, this process seems to be …

Electric current controls water flow through graphene oxide membranes

An international team led by Manchester University, UK has discovered a fascinating property of graphene oxide membranes. (one micron thick membrane made from graphene oxide (GO) with a flake size of approximately 10 μm).  They found that water would pass through the membrane.  However when they applied an electric current across the membrane the water flow …

Extraordinary water adsorption characteristics of graphene oxide

This is a combined effort of researchers from Australia India and Japan. The paper is available at this link. They looked at the way graphene oxide nanoplates (GO) interacted with water vapour. They observed that GO imparts a very high water uptake capacity up to 0.58 gram of water per gram of GO (g g-1) …

New graphene / polymer composite made by bonding nanoplates

This is work done by a joint Chinese and American team. They have glued together graphene nanoplates to make a composite that does not need carbon fibre. The graphic shows the steps they had to go through to make this work. The resulting composite conducted electricity and was fairly strong with a tensile strength of …

MIT’s roll-to-roll process making CVD graphene

MIT’s roll-to-roll process making CVD graphene Massachusetts Institute of Technology (MIT) first announced their work making graphene by a continuous process back in 2015. It is a measure of just how difficult this is in practise that over three years later the team is still developing the process. They are making good progress though. Now …
