Bluestone Global Tech logoBGT Materials Limited (previously BlueStone Global Tech) was a Manchester, UK based graphene producer. BGT offered fully customizable graphene on several substrates (Quartz, Copper, Silicon and others).

BGT Also offered a range graphene and graphene oxide based products, including suspensions, inks and membranes. The company seems no longer to be in business.

In September 2013 BGT announced plans to collaborate with Manchester University on several graphene projects, including research into supercapacitors, plasmonics and filtration membranes. BGT was the first industrial partner of the £60-million National Graphene Institute at the University of Manchester.

The company has spun-off two companies, Graphene Lighting (that aims to commercialize LED lighting enhanced by graphene) and Graphene Security (that focuses on graphene-based RFID tags and antennas).

In February 2013 the company announced the availability of 24" by 300" graphene-on-copper foils. In April 2013 we interviewed the company's CEO and discussed the company's technology and business.

The latest BGT graphene news:

BGT launches the world's first graphene based Field Effect Transistor (GFET)

Bluestone Global Tech announced a new groundbreaking product today, the world's first graphene based Field Effect Transistor. BGT's Grat-FET is a wafer with 9 different GFET chips (or FET arrays), each with 64 FETs. Grat-FET is aimed towards research and development work and not for commercial production.

BGT's GFETs are fabricated (using CVD) on a silicon wafer covered with a SiO2 layer. The high mobility (2000 cm2/Vs or more) graphene is used as the transistor channel. Each transistor consists of three terminals: source and drain metal electrodes and a global back gate.

Bluestone Global Tech to collaborate with Manchester University on graphene research, to open a production fab too

Bluestone Global Tech decided to open a new European graphene production plant at the University of Manchester. Bluestone will also partner with the University on several projects. Those projects (detailed below) and the pilot production facility are estimated at £5 million ($7.8 million) which will be funded wholly by BGT.

The National Graphene Center planThe National Graphene Center plan

This new deal signs the first strategic partnership of the £61 million National Graphene Institute (NGI) established at Manchester and Bluestone is the first company (except University Spin-Offs Graphene Industries and 2-D Tech) to work at the NGI. Specifically Bluestone will open a pre-production facility and will offer graphene material to the University of Manchester's 100+ scientists and engineers working on graphene and other 2D materials. Later on BGT will setup a larger headquarters and a pilot production line at the NGI and will also work towards partnership with other consumer companies.

The Wall Street Journal reports on the graphene IP gold rush

The wall street journal posted an interesting article and video on graphene. The article discusses the current state of research and business, possible graphene applications and the rush to patent related technologies.

The article starts with the Cambridge graphene research center and then discusses several companies and their graphene programs, including IBM, Nokia, BlueStone Global Tech, Vorbeck Materials, Lockheed Martin and Aixtron.

Bluestone Global Tech demonstrates their ultra-flexible Gratom-O graphene on PET:

Bluestone Global Tech released a new video showing a test of their Gratom-O product (a graphene film on PET). This flexible film's physical integrity and high conductivity remain completely in tact, even after 25,000 bending cycles:

Gratam-O is a large-area CVD graphene film on PET (it can also be transferred to customized substrates). It features low sheet resistance and high optical transmittance (over 97%).

BGT shows Powerbooster's graphene-based touch panels

Last month we posted about Shanghai's Powerbooster Technology and their graphene-based flexible touch-panels for mobile devices. The company is using Bluestone Global Tech's graphene to produce those panels. BGT now posted a nice video showing these touch panels in action:

According to Powerbooster, they are already producing and selling around two million touch panels each month, apparently to mid-sized Chinese smartphone makers. The first products will reach the market by the end of 2013.
