EdEarl Posted July 10, 2016 Posted July 10, 2016 First produced in 2004, graphine production per year is now 205 tons and growing. Manchester School of Physics and Astronomy Between 2009 and 2013, global production rose from 12 to 205 tons, with a market value today of $10-m. Novel graphene-based technologies are being developed by many multinational companies, for example IBM, Samsung, BASF, Nokia, SanDisk and Fujitsu. The first pioneering products have already reached the market: Sports equipment manufacturer HEAD has reinforced tennis racquets with graphene to make them lighter and easier to handle. HEAD predicts sales of $30-m in 2013. Shanghai-based Powerbooster has collaborated with graphene producer Bluestone Global Tech to manufacture graphene-based touch screens. In 2013, monthly revenues from these screens reached $10 million. Vorbeck Materials has developed Vor-ink – a graphene-based conductive ink for printed electronics. Customer demand spurred Vorbeck to increase its production capacity to over 40 tons and open an additional production facility. Vorbeck has used Vor-ink to create a printed anti-theft packaging system for MeadWestvaco, a global packaging company. The system has been adopted by major US retailers Home Depot and CVS, generating annual revenues of $1-2.4-m for Vorbeck.

Endy0816 Posted July 10, 2016 Posted July 10, 2016 Yeah, good to see. More of a carbon society we have the better.
EdEarl Posted July 10, 2016 Author Posted July 10, 2016 Yeah, good to see. More of a carbon society we have the better. You got that right. I expect to see better batteries and supercapacitors that will change transportation from petrol to electric. Perhaps graphene can be used in 3D printed motors; if so the weight and cost of motors should fall as graphene prices fall. It is a great armor. https://www.newscientist.com/article/dn26626-bulletproof-graphene-makes-ultra-strong-body-armour/ It makes a desalinization membrane. http://cleantechnica.com/2015/04/03/methane-rescue-new-energy-efficient-graphene-desalination-membrane-99/ Graphene light bulbs are more efficient than LED and last longer. http://physicsworld.com/cws/article/news/2015/jun/18/graphene-light-bulb-shines-bright And many more.
MigL Posted July 10, 2016 Posted July 10, 2016 I don't think they're more efficient ( or could be ) than LED bulbs. They're still an incandescent light emitter, and so, waste a lot of energy as heat.

It is the graphene enhanced LED that is 10% more efficient with a longer life span. http://www.geek.com/chips/graphene-enhanced-led-light-bulb-is-cheaper-more-efficient-longer-lasting-1619454/
imatfaal Posted July 11, 2016 Posted July 11, 2016 I have seen adverts for Graphene bicycle tyres (added element rather than made from) ! Not sure that is anything other than mad hype - although my current tyres do have kevlar so they are not averse to adding some pretty exotic materials to them
DrP Posted July 12, 2016 Posted July 12, 2016 (edited) They were talking about graphine powder in primers at a coatings show I recently attended. Apparently a very small inclusion of the material into a primer coat can prevent corrosion and rusting on a metal substrate. I was going to try some out, but they were wanting £250.00 for a very tiny sample. It got me thinking... why would it be a good rust preventer? Maybe it is very electron withdrawing?

EdEarl Posted July 12, 2016 Author Posted July 12, 2016 A little bit of graphene goes a long way, about 2630m2/g.
