2.4. Dynamic mechanical analysis (DMA)
The dynamicmechanical properties (storagemodulus and tan δ) of a
rectangular specimen 3.27 × 12.7× 63.5mmin sizewere assessed using
a DMA model Q800 from TA Instruments. The experiments were performed
using a dual cantilever clamp with a temperature range of
−150 to 100 °C heated at 3 °C/min, 1 Hz as the frequency and 20 μm
as the oscillating amplitude.
