Report on measurement procedures developed for the accurate analysis of the morphology and structure of GFMs

The three classes of laboratory-scale GFMs (graphene, GO, and functionalized graphene) synthesised by UniTo will constitute the base material for systematic morphological characterisation and method development in this task. High-resolution SEM, STEM-in-SEM, and AFM will be used by BAM and (HR)TEM by UOxf to precisely characterise the morphology of the GFMs from WP1. In the first phase (M2-6), sample preparation procedures (powders and liquid suspension) will be developed or available knowledge optimised to obtain homogeneous and accurate depositions of the GFMs as individual objects on a suited substrate.Correlative approaches, such as with SEM in different detection modes (InLens, transmission mode), but also with TEM, SAED, AFM, and imaging ellipsometry, will be developed by both BAM and UOxf. Descriptive microscopy procedures to quickly andapproximately indicate the size and shape of GFMs, in addition to accurate and sophisticated approaches, will be elaborated jointly by BAM and UniTo. The morphological data will be prepared for WP4 (by EwC).
