Graphene Oxide: Introduction and Market News - Page 20

China Carbon Graphite Group, a producer engaging in the research and development, production and sales of graphene and graphene oxide, recently announced a pilot scale production of high quality graphene and GO in a collaboration with Hunan University.

CCGG has collaborated with Hunan University on graphene research since 2012, and was able to previously produce graphene oxide in a multiple-step process. Now the Company can reportedly integrate multiple steps into a single process in a less than medium pilot scale.

The European Commission has released an interim review report of the Graphene Flagship project's first year following the two-and-half-year ramp-up phase. The Graphene Flagship was concluded to have achieved most of its objectives and milestones and delivered exceptional results with significant immediate or potential impact. The Graphene Flagship is further commended for focusing its work towards a more industrially oriented initiative with a higher Technology Readiness Level.

The report mentioned several significant results close to commercial exploitation, including work with Airbus to produce aircraft parts made of graphene composites, a motorcycle helmet with a graphene coating, a new viscoelastic graphene-polymer sensor material, perovskite photovoltaic cells with improved stability and a demonstration of tuneable ion sieving using GO membrane for water desalination.

An international group of researchers, including scientists from Shinshu University in Japan and Penn State’s ATOMIC Center, created a graphene and graphene oxide-based coating for desalination membranes which are said to be more scalable and sturdier than current nanofiltration membrane technologies available.

The result of this creation would hopefully be a filter for clean water solutions, protein separation, wastewater treatment, as well as pharmaceutical and food industry applications. This membrane uses a simple spray-on technology to coat a mixture of graphene oxide and graphene in solution onto a backbone support membrane of polysulfone that is modified with polyvinyl alcohol. The team reports that even in the early stages of the development of the membrane, it can already reject 85% of salt, which is sufficient for agricultural purposes, and 96% of dye molecules.

Ionic Industries recently announced a process for economically mass-producing graphene micro supercapacitors and added that its directors and key personnel have taken direct stakes in the company.

Ionic stated that since it published the positive results on its graphene micro planar supercapacitors 2 years before, the company has been working toward developing a device that not only demonstrates similar performance but can be produced at scale to deliver an economically viable device.

The National Science Foundation recently awarded University of Wisconsin-Milwaukee scientists $1.5 million to perfect a method of mass-producing graphene-based small water sensors using inkjet printing. The goal is to determine whether the process can be customized in order to scale up production and in a more economic way than traditional manufacturing methods.

The graphene-based sensors, developed at UWM, reportedly outperform current technologies in accuracy, sensitivity and sensing speed. Their performance and size make them useful for continuously monitoring drinking water for miniscule traces of contaminants like lead.

Researchers from The University of Manchester recently demonstrated flexible graphene-based supercapacitors printed directly on to textiles using a simple screen-printing technique.

The solid-state flexible supercapacitor device has been demonstrated by using conductive graphene-oxide ink to print onto cotton fabric. The printed electrodes reportedly exhibited excellent mechanical stability due to the strong interaction between the ink and textile substrate.

Researchers at the UAE-based Masdar Institute, part of the Khalifa University of Science and Technology, have announced significant progress in their research in the field of optimized graphene-based membranes, which aim to make water filtration and desalination more efficient and sustainable.

The team worked to develop membranes made of layered reduced graphene-oxide sheets that are able to block the passage of salt ions in a membrane-based seawater desalination process. The spacing between the sheets is what ultimately affects the membrane’s efficacy, or its ability to filter impurities like salt ions while still permitting water molecules to pass through. The spaces between sheets must be just right if they are too large and salt ions are not filtered out, and if they too small and even water molecules are unable to penetrate the membrane.

Graphenea recently announced the opening of a new graphene oxide (GO) pilot plant with 1 tonne per annum production capacity. The new plant is meant to significantly increase production capacity for Graphenea (which is already producing GO dispersions, powders, and films), while also allowing for higher quality and batch-to-batch reproducibility. The plant reportedly houses in-line quality control of each individual batch.

Graphenea stated that although the production volume is large, the new plant can accommodate custom requirements regarding flake size, oxygen levels, and other specifications. Orders for multi-kilogram quantities will be processed with short delivery times. The production capacity is multiplied by 20 times compared to capabilities before the pilot plant, allowing for development and industrial scale supplies.
