Description: Confocal Raman microscopy and spectroscopy technique allows to identify various chemical components (polymers, oxides, etc.) and map their distribution in an area mapping or across the coating thickness in confocal regime. Raman spectra provide fundamental information about all possible changes in material structures induced by defects, pressure, and temperature. Also, cross-linking reaction and degree can be characterized with help of Raman spectroscopy and mapped using Raman microscopy. Raman Spectroscopy is a powerful tool to characterize 2D materials such as graphene, graphene oxide, MoS2, MXenes, etc. and any their structural changes and flake thickness.
