IEC TS 62607-6-19:2021(E) establishes a standardized method to determine the chemical key control characteristic • elemental composition for powder consisting of graphene-based material by • CS analyser and ONH analyser. The method as described in this document determines the content of carbon (C), sulfur (S), oxygen (O), nitrogen (N) and hydrogen (H). The carbon (C) and sulfur (S) content…

IEC TS 62607-6-6:2021(E) establishes a standardized method to determine the structural key control characteristic • strain uniformity for single-layer graphene by • Raman spectroscopy. The width of the 2D-peak in the Raman spectrum is analysed to calculate the strain uniformity parameter which is a figure of merit to quantify the influence of nano-scale strain variations on the electronic…

IEC TS 62607-6-10:2021(E) establishes a standardized method to determine the electrical key control characteristic – sheet resistance (Rs) for films of graphene-based materials by – terahertz time domain spectroscopy (THz-TDS). In this technique, a THz pulse is sent to the graphene-based material. The transmitted or reflected THz waveform is measured in the time domain and transformed to the…

IEC 62899-201-2:2021(E) defines measurement methods for the properties of stretchable substrates, in order to use evaluating stretchable functional layers (conductive, semiconducting, and insulating) formed by printing technologies. If the same types of materials as the substrates are used for the cover lay film, they are also subjected to the measurement defined in this document. Stretchable…
