“…In recent years, terahertz spectroscopy with a longer band than infrared can fill the gap in this field. Terahertz time-domain spectroscopy (THz-TDS) has become an important tool for identifying material components and analyzing material characteristics [13][14][15][16] owing to its advantages of being non-contact, non-invasive, strong penetrability and high sensitivity [17][18][19]. HDPE is often used and tested as a substrate material in the terahertz range [20,21], Stefan Sommer et al [22] distinguished the crystalline state of HDPE by refractive index, and the adsorption characteristics of HDPE have been studied by Gas chromatography [8], liquid chromatography [23,24], etc.…”

The optical properties of high-density polyethylene (HDPE) in the terahertz band are characterized by terahertz time-domain spectroscopy (THz-TDS). The results show that the THz-TDS can effectively distinguish the particle size of HDPE and filler content of HDPE. And it can also be used to characterize the adsorption characteristics of HDPE. These indicate that it can improve the performance of HDPE, industrial production and even environmental pollution of micro-size of HDPE.
