A Comparison of THz Spectroscopy Measurements of Carbon Nanotubes Embedded in Polymer Matrices

Terahertz spectroscopy is used to obtain the optical parameters of polypropylene samples with different concentrations of multi walled carbon nanotubes. Results are put in context with previous works utilizing other kinds of polymer matrixes and an noticeable discrepancy in the behavior of attenuation with increasing loading content is found.
