Coherent vibrations in 'polar/non-polar'-like complex polymeric mixtures -A dielectric approach to percolation phenomena

The analysis of thermostimulated currents by the fractional polarization pr ocedure has been used to establish the existence of a coherent vibration in 'Linseed oil/mastic varnish' mixtures. This excitation is seen in the oil component when its proportion in the system is inferior to its percolation threshold. The observed phenomenon complies with compensation laws and is i nterpreted in the framework of the formalism developed by Frohlich to under stand collective phenomena in biological systems.
