Mechanical Property Mapping

Nanomechanical contact resonance spectra that can be used to differentiate materials based on their viscoelastic properties

Lorentz Contact Resonance (LCR) creates nanomechanical contact resonance spectra that can be used to differentiate materials based on their viscoelastic properties. LCR maps the distribution of multiple components of a sample, and allows precise location of the probe for subsequent chemical and/or thermal analysis. Since LCR uses proprietary self-heating ThermaLever™ probes, it can also rapidly measure temperature-dependent variations in a sample’s mechanical properties. The technique has provided exciting results for: 

  • Polymer blends
  • Multilayer films
  • Composite materials
  • Life sciences
