Abstract

A novel route for morphological characterization of phase separating toughener and cross-linker for epoxy matrices has been investigated using fluorescence spectroscopy. Phase behavior of the individual components is determined by attaching different fluorescent probes to the toughener and cross-linker. In contrast to other techniques such as transmission eletron microscopy (TEM), this method allows resolution between similar components in which selective staining cannot be achieved.
