The optical properties of polyvinyl chloride have been investigated by the terahertz time-
domain spectroscopy technology to highlight their application. Optical parameters such as
absorption coefficient, phase difference and refractive index have presented different
characterizations among different particle sizes, types and proportion blends. The
adsorption properties of polyvinyl chloride on methyl orange were studied and characterized
by terahertz spectroscopy at different times. These results provide a database for the efficient …
