Researchers use graphene to improve polymeric coatings

Graphene Oxide Nanoparticles increase Protective Properties of Epoxy-based Anticorrosive Coating

TEHRAN, Aug. 02 (MNA) – Iranian researchers from Institute for Color Science and Technology improved the anticorrosive properties of polymeric coatings by using graphene and creating nanocomposite structures.

Annually, countries spend a large amount of money on corrosion prevention and repairing the damages due to corrosion. Anticorrosive coatings are used to prevent and reduce the above mentioned costs. Organic coatings are widely used to protect metals against corrosion. Epoxy coatings have desirable protective properties in corrosive media due to its unique characteristics. However, the coating is not able to conserve its protective ability for a long time in contact with corrosive media. According to Iran Nanotechnology Initiative Council (INIC), graphene oxide nanoparticles have been used in this research to create nanocomposite structure and increase protective properties of epoxy-based anticorrosive coating.

The use of synthetic nanocomposite coatings for the coating of onshore devices and equipment and in petrochemical units reduces expenses due to the corrosion, and increases the life of equipment, including pipelines.

Graphene oxide-based nanoparticles have recently attracted the attention of researchers due to their unique properties. However, these materials are not compatible or stable in the majority of organic solvents. Therefore, surface modification process should be carried out on these materials by using amine compounds. The nanosheets are able to prevent the diffusion of corrosive agents into the coating or to postpone the diffusion for a while due to their very high specific area. Therefore, the life of the coating increases significantly.

Results of the research have been published in Corrosion Science, vol. 103, 2016, pp. 283-304.

BAC Mono is first to use 'revolutionary' graphene material

Graphene-enhanced Carbonfibre Used in British Sports Car

The BAC Mono has claimed a world first by making use of a revolutionary new substance called graphene.

The model’s British maker has trialled the new lightweight material in the rear arches of its single seater Mono supercar and says it has the potential to offer serious performance and cost benefits for customers.

Graphene is made from sheets of carbon just one atom thick. It’s lighter and stronger than carbonfibre, which BAC says could mean weight reductions of 20% – a figure that could have significant impacts on performance, fuel economy and cost.

BAC has worked with Haydale Composite Solutions on the trial, which used graphene-enhanced carbonfibre, and decided to focus on the rear arches because of their size and complexity, which allowed the material and manufacturing process to be thoroughly tested. The car was showcased at the Science in the City festival in Manchester.

Major Chinese Investment in Graphene Helps Develop Lighter Planes

A five-year collaborative research project will be executed by the Beijing Institute of Aeronautical Materials (BIAM) and the National Graphene Institute (NGI) at The University of Manchester.

The study will concentrate on composites with improved performance in the field of mechanical, electric conductive, and thermal conductive behavior. It will also focus on the compatibility of the matrix materials and graphene. This research has the potential to introduce the applications of graphene in varied components and materials in the aerospace sector. It will also help to improve the performance and save weight.

The research will also influence aircraft, high-speed trains, and industrial equipment, replacing the use of conventional materials.

The deal was announced at the opening of the European Science Open Forum in Manchester by Professor Robert Young, who heads the research project at The University of Manchester.

Professor Young, speaking at a session called ’Science and Aviation’, organized in partnership with Manchester Airport and Hainan Airlines, will outline how graphene could revolutionize the future of trains and planes.

The announcement was made in parallel to a senior delegation from Manchester – including a Nobel-prize winning scientist who was responsible for isolating graphene – being in Beijing in order to promote the city as a global destination for inward investment and tourism.

Graphene has become a part of the recently developed Chinese five-year plan, and the country is also beginning to develop improvements in its domestic civil aerospace industry and also enhance their expertise of materials.

This new project will go on until 2020, and it will include collaborative research on graphene projects, strengthening the exchange of personnel between Beijing and Manchester and the ties in graphene technology.

This collaborative effort is an extension of a project that started in 2015. This earlier project focused on developing graphene composites using metals including aluminum. This extended version of the project was based on the success of the partnership.

Several other UK companies, particularly in aerospace, are expected to become directly involved during the progress of the project.

Graphene oxide sheets to transform dirty water into drinking water

Graphene oxide has been hailed as a veritable wonder material; when incorporated into nanocellulose foam, the lab-created substance is light, strong and flexible, conducting heat and electricity quickly and efficiently.

Now, a team of engineers at Washington University in St. Louis has found a way to use graphene oxide sheets to transform dirty water into drinking water, and it could be a global game-changer.

“We hope that for countries where there is ample sunlight, such as India, you’ll be able to take some dirty water, evaporate it using our material, and collect fresh water,” said Srikanth Singamaneni, associate professor of mechanical engineering and materials science at the School of Engineering & Applied Science.

The new approach combines bacteria-produced cellulose and graphene oxide to form a bi-layered biofoam. A paper detailing the research is available online in Advanced Materials.

“The process is extremely simple,” Singamaneni said. “The beauty is that the nanoscale cellulose fiber network produced by bacteria has excellent ability move the water from the bulk to the evaporative surface while minimizing the heat coming down, and the entire thing is produced in one shot.

“The design of the material is novel here,” Singamaneni said. “You have a bi-layered structure with light-absorbing graphene oxide filled nanocellulose at the top and pristine nanocellulose at the bottom. When you suspend this entire thing on water, the water is actually able to reach the top surface where evaporation happens.

“Light radiates on top of it, and it converts into heat because of the graphene oxide — but the heat dissipation to the bulk water underneath is minimized by the pristine nanocellulose layer. You don’t want to waste the heat; you want to confine the heat to the top layer where the evaporation is actually happening.”

The cellulose at the bottom of the bi-layered biofoam acts as a sponge, drawing water up to the graphene oxide where rapid evaporation occurs. The resulting fresh water can easily be collected from the top of the sheet.

The process in which the bi-layered biofoam is actually formed is also novel. In the same way an oyster makes a pearl, the bacteria forms layers of nanocellulose fibers in which the graphene oxide flakes get embedded.

“While we are culturing the bacteria for the cellulose, we added the graphene oxide flakes into the medium itself,” said Qisheng Jiang, lead author of the paper and a graduate student in the Singamaneni lab.

“The graphene oxide becomes embedded as the bacteria produces the cellulose. At a certain point along the process, we stop, remove the medium with the graphene oxide and reintroduce fresh medium. That produces the next layer of our foam. The interface is very strong; mechanically, it is quite robust.”

The new biofoam is also extremely light and inexpensive to make, making it a viable tool for water purification and desalination.

“Cellulose can be produced on a massive scale,” Singamaneni said, “and graphene oxide is extremely cheap — people can produce tons, truly tons, of it. Both materials going into this are highly scalable. So one can imagine making huge sheets of the biofoam.”

“The properties of this foam material that we synthesized has characteristics that enhances solar energy harvesting. Thus, it is more effective in cleaning up water,” said Pratim Biswas, the Lucy and Stanley Lopata Professor and chair of the Department of Energy, Environmental and Chemical Engineering.

“The synthesis process also allows addition of other nanostructured materials to the foam that will increase the rate of destruction of the bacteria and other contaminants, and make it safe to drink. We will also explore other applications for these novel structures.”
