Preliminary results towards the mechanical characterization of cellulose nanofibers using HarmoniX mode atomic force microscopy

The characterization of mechanical properties cellulose based nanomaterials at the nanometer scale is fundamental in development and optimization a broad range technological products where these are used for their unique physical chemical properties. HarmoniX an atomic force microscopy (AFM) technique which takes advantage use T-shaped cantilever, torsion excited during surface scan tapping mode. This results torsional signal that can be analyzed real time to map, simultaneously topographic reconstruction, sample like elastic modulus, tip-sample adhesion, or energy dissipation indentation cycle. Here we report preliminary concerning capability characterize nanocellulose fibers from hazelnut tree shells previously separated matrix via treatment.
