Foreword

ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work.

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types of document should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives or www.iec.ch/members_experts/refdocs).

ISO and IEC draw attention to the possibility that the implementation of this document may involve the use of (a) patent(s). ISO and IEC take no position concerning the evidence, validity or applicability of any claimed patent rights in respect thereof. As of the date of publication of this document, ISO and IEC had not received notice of (a) patent(s) which may be required to implement this document. However, implementers are cautioned that this may not represent the latest information, which may be obtained from the patent database available at www.iso.org/patents and https://patents.iec.ch. ISO and IEC shall not be held responsible for identifying any or all such patent rights.

This document was prepared jointly by Technical Committee ISO/TC 229, Nanotechnologies, and Technical Committee IEC/TC 113, Nanotechnology for electrotechnical products and systems, and in collaboration with the European Committee for Standardization (CEN) Technical Committee CEN/TC 352, Nanotechnologies, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement). The draft was circulated for voting to the national bodies of both ISO and IEC.

This second edition cancels and replaces the first edition (ISO/TS 80004‑13:2017) which has been technically revised.

The main changes are as follows:

addition of the term "graphene-related 2D material (GR2M)";
expansion of defined terms to include "enhanced", "modified", "enabled" and "based", and derivatives thereof;
indication that use of some terms are deprecated.

Introduction

Over the last decade, huge interest has arisen in graphene, both scientifically and commercially, due to the many exceptional properties associated with this material, such as the electrical and thermal conductivity. More recently, other materials with a structure similar to that of graphene have also shown promising properties, including:

a) monolayer and few-layer versions of hexagonal boron nitride (hBN);

b) transition metal dichalcogenides such as molybdenum disulphide (MoS₂) and tungsten diselenide (WSe₂);

c) silicene and germanene;

d) layered assemblies of mixtures of these materials.

These materials have their thickness constrained within the nanoscale or smaller and consist of between one and several layers. These materials are thus termed two-dimensional (2D) materials as they have one dimension at the nanoscale or smaller, with the other two dimensions generally at scales larger than the nanoscale. A layered material consists of 2D layers weakly stacked or bound to form three-dimensional structures. Examples of 2D materials and the different stacking configurations in graphene are shown in Figure 1. 2D materials are not necessarily topographically flat in reality and can have a buckled structure. They can also form aggregates and agglomerates which can have different morphologies. 2D materials are an important subset of nanomaterials.

It is important to standardize the terminology for graphene, graphene-related and other 2D materials at the international level, as the number of publications, patents and organizations is increasing rapidly. Thus, these materials need an associated vocabulary as they become commercialized and sold throughout the world.

The document contains general terms related to 2D materials, those related to graphene, and those related to other 2D materials. It provides terms related to commonly used methods for producing and characterising 2D materials along, with terms related to 2D materials characteristics. It also includes performance related terms, such as “-enhanced” and “-enabled”, and those related to composition, such as “-based” and “-modified”, as shown in Figure 2.

This document belongs to a multi-part vocabulary, covering the different aspects of nanotechnologies. It builds upon ISO 80004‑1, ISO/TS 80004‑3 and ISO/TS 80004‑6, and uses existing definitions where possible.

1 Scope
