What are the common techniques used for mechanical testing of nanomaterials?
Several techniques are employed to measure the mechanical properties of nanomaterials. Some of the most common methods include:
Nanoindentation: This technique involves pressing a hard, sharp tip into the surface of a material to measure its hardness and elastic modulus. Atomic Force Microscopy (AFM): AFM can be used to measure the surface forces and mechanical properties at the nanoscale by scanning a cantilever over the sample surface. Tensile testing: Although traditionally a macro-scale test, it can be adapted for nanowires and nanofibers to measure their mechanical properties. Scanning Electron Microscopy (SEM): SEM can be used in conjunction with mechanical testing to observe deformation and failure mechanisms at the nanoscale.
