Dynamic mechanical thermal analysis was performed on a TRITON
Tritec 2000 dynamic mechanical analyzer in single cantilever
bending mode. The storage modulus (E), loss modulus (E) and loss
factor (tan ı) were measured as a function of temperature at a frequency
of 1 Hz, heating rate of 2 ◦C/min and temperature range of
25–120 ◦C. The strain was set at 0.005%. At least two samples of each
material were tested and the average value of these parameters for
each material was calculated and reported.
