摘要：

An oxidized carbon fiber has been modeled as a thin polymeric film, representing the surface species, coated with a graphite overlayer. Optical theory has been utilized to calculate the variations in the electric field intensities that occur when the graphite layer is overlayed on a film of PV Ac (polyvinylacetate). The increase of the 〈Ez2〉 component has been observed. Spectral simulations based on Hansen's formulas clearly show the enhancement of the infrared absorbances. The enhancement proves to be dependent on the air gap thickness existing between the germanium element and the polymeric film and on the nature of the substrates.
