Dynamic mechanical analysis of polymer coatings by nanoindentation at elevated temperature
Dynamic mechanical properties play an important role in development and quality control of polymeric thin films. Due to the small volume of the material, dynamic nanoindentation is often the only method suitable for obtaining these properties. This application report shows the characterization of epoxy adhesive films via dynamic nanoindentation at elevated temperatures.
Nanoindentation probes the mechanical properties of materials like elastic modulus and hardness at the nanoscale. Its high resolution in both force and depth and lateral displacement makes it a powerful tool for a wide range of applications from thin films to micro-electronic devices. Nanoindentation measures the normal force vs. penetration depth yielding a force-displacement curve. The material properties are calculated according to the Oliver and Pharr method. The indenter tip area, indispensable for correct calculation of instrumented indentation elastic modulus EIT and hardness HIT, is calibrated against fused quartz, which has known elastic modulus and Poisson’s ratio.
