Characterizations of high-density polyethylene by terahertz time-domain spectroscopy

Abstract

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.
