We demonstrate the unusual applications of the recently developed mirage-Fourier transform infrared (FTIR) spectroscopy for nondestructive characterization of polymer coatings, especially on absorbing substrates or very thin coatings, where conventional FTIR techniques tend to fail. The mirage-FTIR

β¦ Synopsis
Carbon fiber, being black (high absorptivity) material, is difficult to analyze by the conventional infrared (IR) techniques. Probably due to this fact, most of the studies reported in literature have been restricted to the thermal degradation of polyacrylonitrile-based fibers only. In the present work, we have used a recently developed mirage-FTIR technique for recording the IR spectra of carbon fibre at different stages of production, right from the precursor to final product. A study of microstructural/ chemical changes occuring not only provides the information on structure but also demonstrates an unusual and highly technical industrial application.

In this work, polyacrylonitrile (PAN) -based activated carbon fibers (ACFs) were developed by the common processes of stabilization, carbonization, and steam activation. Those fibers were successively subjected to heat treatment in a vacuum at high temperature and reactivation in steam. The changes
A rayon-based graphitized carbon fiber has been oxidized and its surface has been studied by Fourier transform infrared attenuated total reflection spectroscopy (F'TIR-ATR). The spectra of the samples oxidized for different times are compared and the bands at 1720 cm-' and 1580 cm-', arising from th
