MICRORAMAN ANALYSES OF EPOXY CROSS-LINKING REACTION

Epoxy based materials find a number of applications. Suitability of these materials demands the process of crosslinking, which among others influences the final mechanical and thermal properties. Raman spectroscopy is a modern research and analytical tool providing specific information of a molecular structure. Prime advantages of Raman spectroscopy are non-destructivness, rapidity, contactless, no special requrements for sample preparation and others. The essence of the vibrational method along with the almost all natural sciences and technical and industrial disciplines. This paper is focused on using Raman microspectroscopy as an innovative method for monitoring and analyses of epoxy resin cross-linking reaction. The study of the proccess comprises principal chemical bonds identification, their localisation in Raman spectra and their time behaviour. Experimantal data demonstrate the changesin structure during the crosslinking reaction. In regard of the rapidity of measurement a quasi real time monitoring of epoxides curing is feasible.
