Abstract
We investigated the property changes of medical film cross-linked by electron beam (e-beam) irradiation, using THz time-domain spectroscopy (TDS). The cross-linked medical film showed higher refractive indices and absorption coefficients than those of reference film in the THz regime. THz-TDS have a potential for monitoring of cross-linking on the medical film. In addition, the THz-TDS method has potential as a practical nondestructive technique for polymer examination and analysis.
