Abstract :
The glass transition temperature Tg of polymers is identified by terahertz (THz) time-domain spectroscopy (TDS). The THz refractive index n of the investigated material changes significantly in the region of the glass transition. Hence, THz TDS offers the possibility for non-contact polymer analysis.
