What's Happening?
The International Organization for Standardization (ISO) has released two new standards concerning graphene-related two-dimensional (2D) materials. The first standard, ISO/TS 9651:2025, provides a classification framework for these materials, detailing their characteristics and measurement methods for commercial applications. It includes guidelines for consistent naming and descriptions, as well as a technical data sheet template. The second standard, ISO/TS 23359:2025, focuses on the chemical characterization of graphene-related 2D materials in powders and liquid dispersions. It specifies methods for determining elemental composition, oxygen to carbon ratio, trace metal impurities, and other chemical properties using techniques such as X-ray photoelectron spectroscopy and Fourier-transform infrared spectroscopy.
Why It's Important?
These standards are significant as they provide a structured approach to the classification and chemical characterization of graphene-related 2D materials, which are increasingly used in various industries. By establishing clear guidelines, the ISO aims to enhance the reliability and consistency of these materials in commercial applications, potentially boosting innovation and development in sectors such as electronics, energy storage, and materials science. The standards could also facilitate international trade by ensuring that products meet global quality benchmarks, thereby benefiting manufacturers and consumers alike.
