This webinar will start with some basic nanoindentation theory and focus on its shortcomings with regards to the unique mechanical characteristics of polymers, particularly their strong time-dependence. To overcome this shortcoming, a nanoscale compliment of Dynamic Mechanical Analysis, Bruker’s nanoDMA III presented. This simple method measures both storage (E’) and loss (E’’) modulus of polymeric materials in a meaningful way.
Having the basics in hand, the nanoDMA III technique can then be applied to increasingly difficult (and often more rewarding) measurements:
• Combining effects of time and temperature for something easy; a thermoplastic, then something more difficult; a liquid silicone.
• Advantages of small-scale testing of bulk polymers over a wide variation in humidity conditions.
• Measuring temperature effects on adhesion, E’ & E’’, and uniformity of coating for pressure sensitive adhesives.
