ISO publishes standard on matrix of properties and measurement techniques for graphene

The International Organization for Standardization (ISO) has published standard ISO/TR 19733:2019, “Nanotechnologies — Matrix of properties and measurement techniques for graphene and related two-dimensional (2D) materials”.

ISO states that since graphene was discovered in 2004, it has become one of the most attractive materials in application research and device industry due to its supreme material properties and it is expected that applications of graphene could replace many of the current device development technology in flexible touch panel, organic light emitting diode (OLED), solar cell, supercapacitor, and electromagnetic shielding.

NUS team offers a way to fight fake Graphene

Researchers from the National University of Singapore (NUS) have set out to tackle the issue of a lack of graphene production standards, which leads to many cases of poor quality graphene from suppliers. The team developed a systematic and reliable method for establishing the quality of graphene samples from around the world. They were able to achieve this by using a wide range of analytical techniques and tested samples from many suppliers.

Upon analyzing samples from over 60 different providers from the Americas, Asia, and Europe, the NUS team discovered that the majority contained less than 10% of what can be considered graphene flakes. The bulk of the samples was graphite powder that was not exfoliated properly.

New graphene metrology service by Graphene-Info

Graphene-Info has teamed up with world renowned laboratories to offer a unique graphene metrology service that provides characterization and analysis on graphene materials.

Dozens of companies are producing various types of graphene materials, which causes much diversification and confusion. Our metrology service offers graphene producers the chance to obtain valuable test results and post-testing analysis and interpretation, that assist in proving viability and quality of production. In addition, displaying critical data to customers like the material characteristics and potential applications is key to successful marketing and sales activities.

BSI launches new guide for graphene properties and use

BSI, the UK-based standards body and global certification company, has published a new guide to the properties of graphene flakes, PAS 1201. The guide provides an explanation of the physical and chemical properties of graphene flakes, and advice on information manufacturers and suppliers of graphene should give to prospective users.

Dan Palmer, Head of Manufacturing at BSI, says: “PAS 1201 sets out the information that any manufacturer or interested party needs to understand about graphene before introducing this material to the manufacturing process. Standardizing the information that is made available about properties of graphene flakes is important in order for the commercial opportunities of graphene in the UK to be realized.”

New EU consortium launched to handle REACH graphene registrations

A new consortium (called the Graphene REACH registration consortium) was launched in 2017 to handle REACH graphene registration in the EU. The consortium members, The Sixth Element Material Technology, NanoXplore and Applied Graphene Materials announced that the joint registration dossiers for graphene and graphene oxide have been submitted to the ECHA.

The consortium is also preparing a JRD for reduced graphene oxide, and hopes to submit it before the end of 2018. The consortium issues a callout for companies (whether graphene producers or importers) to join the consortium or buy a letter of access to the new registrations.
