Picto-MICROMICROscopie

Microscopy tools

The purpose of this technical centre is to characterise and highlight the morphologies and structure of the materials synthesised within the unit and to do so relies on a large instrumental park inside the unit, but also located on the Lyon platforms CTµ and CLYM.

Possible characteristics and achievements

  • Preparation of materials Massive polymers, in multiple layers, in powder form, soft (Elastomer, hydrogel, etc.), in solutions for microscopy and spectroscopy analyses.
  • Morphological characterisation of materials at different scales and information on their composition.
  • Observations in different modes, environments (high temperature, low temperature, hydrated, etc.)

Examples of achievements
