Temperature modulated dielectric analysis (TMDA): a new experimental technique for the separation of temperature and reaction effects in dielectric cure monitoring signals

摘要

An early development of a new experimental technique is presented in this communication. Temperature modulated dielectric analysis (TMDA) employs the well-established method of temperature oscillations in order to separate the combined effects of temperature and of the polymerization reaction in the cure of epoxy resins. A novel experimental cell was designed, built and tested for the TMDA measurements. The cell performance was assessed and the results shown here suggest that temperature modulated dielectric measurements are feasible.
