ISO/TR 19733-2019 pdf free.Nanotechnologies—Matrix ofproperties and measurement techniques for graphene and relatedtwo-dimensional (2D) materials.
This document provides a matrix which links key properties of graphene and related two-dimensional(2D) materials to commercially available measurement techniques. The matrix includes measurementtechniques to characterize chemical, physical, electrical, optical, thermal and mechanical properties ofgraphene and related 2D materials.

Terms and definitions, symbols and abbreviated terms.For the purposes of this document, the terms and definitions given in ISo/TS 80004-13 and thefollowing apply.material,consisting of one orseveral layers with the atoms ineach layer strongly bonded to neighbouringatoms in the same layer, which has one dimension, its thickness, in the nanoscale or smaller, and theother two dimensions generally at larger scales
Note 1 to entry:The number oflayers when a two-dimensional material becomes a bulk materialvaries dependingon both the material being measured and its properties. In the case of graphene layers, it is a two dimensionalmaterial up to 10 layers thick for electrical measurementsB]4, beyond which the electrical properties of thematerial are not distinct from those for the bulk (also known as graphite).
Note 2 to entry:Interlayer bonding is distinct from and weaker than intralayer bonding.Note 3 to entry:Each layer may contain more than one element.
Note 4 to entry: A two-dimensional material can be a nanoplate.[SOURCE: ISO/Ts 80004-13:2017,3.1.1.1]
Note 5 to entry: The related 2D materials in this document refer to the graphene -derived materials such asgraphene oxide and reduced graphene oxide and other 2D materials with a structure similar to that of grapheneshowing promising properties including but not limited to monolayer and few-layer versions of hexagonal boronnitride (hBN), molybdenum disulphide(MoSz), tungsten diselenide (WSez) silicene and germanene and layeredassemblies of mixtures of these materials.ISO/TR 19733 pdf download.
