Towards Standardised Procedures for Morphology Measurement of 2D-Materials by Imaging

  • The industry uptake of graphene-related 2D materials (GR2M) material increases, and international standardization is critical to enable commercialization. Reliable, accurate, and reproducible measurements are important due to the multiple production routes and producers of the material to maintain quality in manufacture. Several standards are under development within ISO/TC 229 ‘Nanotechnologies’, i.e. ISO/AWI TS 23879 “Structural characterization of graphene oxide flakes: thickness and lateral size measurement using AFM and SEM” or ISO DTS 23359 “Chemical characterization of graphene in powders and suspensions”, which focus on determining the dimensional and chemical properties of GR2M. Interlaboratory comparisons are required to develop best practice and understand the associated measurement uncertainties. In this contribution challenges and solutions for the accurate measurement of the lateral size of GR2M will be discussed based on the results of a recently completedThe industry uptake of graphene-related 2D materials (GR2M) material increases, and international standardization is critical to enable commercialization.

Interlaboratory comparisons are required to develop best practice and understand the associated measurement uncertainties. In this contribution challenges and solutions for the accurate measurement of the lateral size of GR2M will be discussed based on the results of a recently completed interlaboratory comparison organized under the pre-standardisation platform of VAMAS (www.vamas.org/twa41/documents/2023_vamas_twa41_project13_GO_SEM.pdf). Aspects related to sample preparation, measurement conditions, and image analysis with different approaches to extract the corresponding size and shape descriptors will be presented. A discussion on the measurement uncertainty budget associated to the final result will be also included.zeige mehrzeige weniger
