演讲题目:The IEC Roadmap for Standardization of Graphene and Related Materials
内容摘要
Since Andre Geim and Konstantin Novoselov were awarded with the Nobel Prize in 2010 for their work on graphene this material was subject to an enormous amount of research effort to understand its basic properties. Nevertheless graphene used for fundamental research very often is not comparable to raw materials available on the market. A wide range of fabrication methods from chemical exfoliation in liquid solutions to chemical vapor deposition on substrate provides materials with completely different properties.
Therefore it remains difficult to purchase these materials with consistent quality which hinders its broad use in industrial large scale fabrication. For the successful use of graphene and related materials within commercial applications it is essential to develop consensus-based international standards which define the material properties and the measurement protocols to measure them.
On international level this standardization process is performed as a joint effort of IEC, ISO, CENELEC and IEEE and revolves around the central document, the standard IEC 62565-3-1. This so-called Blank Detail Specification (BDS) provides a template that lists all relevant Key Control Characteristics (KCC) and the standardized measurement protocols to measure them. Currently the working draft of IEC 62565-3-1 lists more than 30 KCCs including “number of layers”, “sheet conductance”, and “transmission”. Currently there are no international standards published but the number of standardization projects in the responsible standardization committee IEC/TC 113 is increasing rapidly. In this situation it is evident that all standardization activities on national, regional and international level needs to be coordinated. As IEC 62565-3-1 provides a consensus list of KCCs this standard acts as a roadmap for graphene standardization. Furthermore it is a template for other 2D materials which are also subject for future standardization
This talk will provide a review of the international standardization activities on graphene technologies and present the status reached within the IEC, IEEE and ISO nanotechnology committees and the recently established CENELEC Workshop on “Specifications for Graphene Related Materials (CENELEC WS SGRM)”. It will point out the importance to coordinate the worldwide standardization activities. IEC/TC 113 is the right place to perform this. Therefore all countries are invited to join the committee and submit their New Work Item Proposals to fill the gaps for the KCC measurement procedures and BDS standards for related 2D materials.
