FT-IR of the Polymer-Reinforcement Interphase in Composite Materials

  • Andrew Garton
Part of the Polymer Science and Technology book series (POLS, volume 36)


A modified internal reflection spectroscopy (IRS) technique is described, where the IRS element is coated with a thin (<100 nm) layer of a material intended to simulate the surface of a reinforcement. Examples of coatings include silica, poly(p-phenyleneterephthalamide), carbonized poly(acrylonitrile) and an aminosilane coupling agent. The way in which these surfaces affect the crosslinking kinetics and final crosslinked state of the first 200–400 nm of an amine- or anhydride-cured epoxy resin was then determined by infrared (IR) spectroscopy. Chemical differences detected by spectroscopy are shown to correlate with physical property differences of reinforced epoxy composites.
