抄録

Co–Cr or Ni thin layers were deposited on both sides of a polyethylene terephthalate (PET) film by sputtering. Complex rigidity moduli of these films were measured by a torsional oscillation method under a load of 6.8×10⁵ Pa between room temperature and 200°C. The real and imaginary parts of the complex moduli of the coated films were explainable, qualitatively, in terms of those of the base film and thin metal layers using a simple composite model. The loss moduli of Co–Cr layers were small, as previously shown by a nonresonant, forced stretching oscillation method, while those of Ni were definitely greater in the temperature range above 130°C. Cracks occurred in Ni above 165°C and in Co–Cr at higher than 180°C under the minimal load mentioned above.
