ISO/TR 19733:2019 pdf free download.Nanotechnologies — Matrix of properties and measurement techniques for graphene and related two-dimensional (2D) materials.
ISO/TR 19733:2019 provides a matrix which links key properties of graphene and related two-dimensional (2D) materials to commercially available measurement techniques. The matrix includes measurement techniques to characterize chemical, physical, electrical, optical, thermal and mechanical properties of graphene and related 2D materials.
Graphene is a single layer of carbon atoms with each atom bound to three neighbours in a honeycomb structurelil. Since its discovery in 2004121, graphene has become one of the most attractive materials in application research and device industry due to its supreme material properties such as mechanical strength, stiffness and elasticity, high electrical and thermal conductivity, optical transparency, etc. It is expected that applications of graphcne could replace many of current device development technology in flexible touch panel, organic light emitting diode (OLED), solar cell, supercapacitor, and electromagnetic shielding. To gain deeper understanding of the material properties and to find the ways of mass producing with fine quality, much research on graphene, and similarly on related two-dimensional (2D) materials is being done in universities, research institutes, and laboratories around the globe. However, to lead these revolutionary materials to full commercialization, it is essentially demanded that characterization and measurement techniques for important material properties need to be standardized and globally recognized. In this document, characterization and measurement techniques for particular properties of graphene and related 2D materials which need to be standardized are organized in a form of a matrix. The matrix could serve as an initial guide for developing the necessary international standards in characterization and nwasuremcnts of graphene and related 2D materials.
4 Matrix of properties and measurement techniques for graphene and related 2D materials
Table 1 is a matrix that links the key properties of graphene and related two-dimensional (2D) materials to commercially available measurement techniques. The matrix includes measurement techniques to characterize chemical, physical, electrical, optical, thermal and mechanical properties of graphene and related 2D materials. There are many other techniques that are being used to study graphene and related 2D materials but here we include only those that are widely used and widely commercially available.
Some of techniques in the matrix may not be suitable to all forms of graphene and related 2D materials but can be applied only to a certain form, such as in sheets, powder, or dispersion. It is also possible to produce different measurement results using these techniques depending on the synthesizing methods of graphene and related 2D materials to be characterized, such as chemical vapour deposition (CVD), mechanical exfoliation, or others. The appropriate forms, synthesizing method and sample preparation of graphene or related 2D materials that each technique is applicable to will be specified in individual standards to be developed in future in accordance with this document.
