Abstract:
The present invention provides a deterioration analysis method capable of analyzing in detail deterioration of a polymer material, and in particular deterioration in the surface condition of a polymer material with low conductivity. The present invention relates to a deterioration analysis method including irradiating a polymer material with a metal coating having a thickness of 100 Å or less formed thereon, with high intensity X-rays, and measuring X-ray absorption while varying the energy of the X-rays, to analyze deterioration of the polymer.
