T1 - THz and Mid IR Fourier transform spectroscopy on polyethylene irradiated with Gamma- Co60 radiation N2 - THz and mid IR spectroscopy of high molecular PE (HMW) and ultra high molecular PE (UHMW) reveals modifications of the molecular structure induced by γ-Co60 radiation. UHMW-PE and HMW-PE can be distinguished. The integral absorption in the B1u THz-region can quantitatively describe the amorphization of crystallinity. The formation of trans vinylene unsaturations and the decay of vinyl can be followed by mid IR spectroscopy T2 - IRMMW-THz 2014 - 39th International conference on infrared, millimeter, and terahertz waves CY - Tucson, Arizona, USA DA - 14.09.2014 KW - Thz and Mid IR Fourier transform spectroscopy KW - Polyethylene KW - Gamma-Co-60 radiation KW - Fourier transform spectroscopy KW - Infrared spectroscopy KW - Light absorption KW - Molecular electronic states KW - Polymers KW - MidIR Fourier transform spectroscopy KW - Terahertz spectroscopy KW - THz spectroscopy KW - γ-Co60radiation KW - HMW KW - High molecular PE KW - Ultrahigh molecular PE KW - Molecular structure modifications KW - UHMW-PE KW - HMW-PE KW - Integral absorption KW - B1uTHz-region KW - Crystallinity amorphization KW - Transvinylene unsaturation formation KW - Vinyl decay KW - Absorption KW - Radiation effects KW - Temperature measurement KW - Spectroscopy PY - 2014 UR - http://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=6956355&isnumber=6955975 SN - 978-1-4799-3877-3 U6 - https://doi.org/10.1109/IRMMW-THz.2014.6956355 IS - IEEE Catalog No.: CFP14IMM-ART SP - 1 EP - 2 AN - OPUS4-32699 LA - eng AD - Bundesanstalt fuer Materialforschung und -pruefung (BAM), Berlin, Germany ER -
