1. The same mechanical relaxation phenomenon of polymers can be observed at a higher temperature for a shorter time (or a higher action frequency), or at a lower temperature for a longer time.
2. Therefore, increasing the temperature and prolonging the observation time are equivalent to the molecular motion and the viscoelastic behavior of polymers.
3. This is the principle of time temperature equivalence.
The introduction of the time temperature equivalence principle in this paper is over, and I hope it will be helpful to everyone.
