Dipole dynamics in network-forming epoxy-amine formulations were investigated by dielectric relaxation spectroscopy. The unreacted liquid monomer mixture was characterized by a single ab process at high frequencies. The ab relaxation peak broadens with the progress of chemical reactions and separate

Dielectric relaxation phenomena are analyzed wil.h an exactly solvable model. This is such a general model that it includes typical stochastic processes and models as special cases. The solutions in the frequency domain as well as in the time domain are obtained and dielectric function e(w) is expli
A physically based method is proposed to represent interpenetrating polymer networks and their electromechanical behavior. The mechanical behavior of the material is nonlinear elastic and the electromechanical coupling arises from electrostatic effects often called the Maxwell stress effect. Ha et a
