Beware of new material claims - the case of graphene


Given that graphene is quite the in vogue material for audio applications I wonder how many (if any) of the vendors selling this are actually sourcing the real thing?

@fleschler "Okay, but I stand by whatever Tim Mrock uses in his Omega E-Mats, SR duplexes and SR fuses they all claim have graphene in them."

The word which destroys the valid argument is CLAIM. Where is the proof?

You cannot put 2D atomic level graphene into a liquid, and claim to have the same properties as a one level atomic sheet grafted onto a silicon base. It is not a trivial exercise to slice a one atom thick layer of Graphene which as a potential product is expensive and is still in the development stage of being applied to electronics. 

You can claim you have (the true atom thin) graphene, but proof is "proprietary" or "patent pending". Even as a fine talc powder in a solution, it is not true atom level Graphene.

@geoffkait  Yah. And spiders webs are stronger than steel too - and so what. If spiders webs could be produced in labs there’d be “tons” of marketing hype. And they would already be in use to “rigiditize” speaker cones. Yes, we need a new marketing word for any serious scam :). And Geoff - please identify just how many “tons” of graphene are being produced,where and by what company. The universities and research labs would love to know where to pick it up cheap. You could become useful to science! ;) (not)

Chinese materials company opens new graphene plant in Heilongjiang

Chinese coke company Baotailong New Materials has completed construction of a USD$9.6 million graphene production project in the north of the country and has launched trial-stage operations.

Baotailong completed all work on the facility located in its hometown of Qitaihe in northern Heilongjiang province at the end of last month, the firm said in a statement. The plant boasts an annual graphene output of 50 tons.

Graphene production plant in Canada.

NanoXplore logoCanada-based NanoXplore recently announced a positive feasibility study for its graphene production plant. The company said that the independent feasibility study highlighted several improvement as compared to the project’s preliminary economic assessment (PEA).

NanoXplore is planning to build a 10,000 metric ton/year graphene production plan, which is currently the largest in the world. NanoXplore plans to offer graphene for $10/kg (USD$8/kg) starting from Jan 2020 under the GrapheneBlack brand.

and,

Graphene-Info, based in Israel, claims graphene is “set to revolutionize a lot of industries, including sensors, batteries, conductors, displays, electronics, energy generation, medicine and more.” The Home of Graphene from the University of Manchester has a marvelous video explaining graphene and its endless possible applications.

There are some 100 pure graphene companies (about 15 are public) largely sustained by joint partnerships and investments, i.e., support from legacy corporations, mining companies, government investments, and venture funds. These start-ups are financially risky with sparse sales and no profits. Three years ago, The Graphene Council warned investors, beware of “graphene play” stock investments that may be scam companies. Nevertheless, graphene research and development is turning into an exciting new industry with potential for changing the manufacture of products and their sustainability.

Israeli researchers are also investigating graphene’s value. For example, Ben-Gurion University of the Negev and University of Western Australia researchers have developed a new process for use in energy storage and other material applications that is faster, potentially scalable and surmounts some of the current graphene production limitations. Yaniv Katan, a scientist at Technion, worked on an international team of scientists discovering new ways to turn electricity into light using graphene.

China can’t seem to get dog food right, I don’t think I’d put much trust in their Graphene......Jim
