PROTON CONDUCTION AND IMPEDANCE ANALYSIS IN SUBMUCOSA MEMBRANE

We have investigated proton conductivity in the submucosa membrane. The AC electrical conductivity includes not only DC component but also the component of dielectric dispersion. From the analysis of AC conductivity, it was found that DC electrical conductivity in submucosa membrane begins to increase with the increase of relative humidity around the 48% relative humidity. Furthermore, the static dielectric constant also begins to increase around the 48% humidity. From these results, it is deduced that the hydrophile and large molecule such as hydroxyproline in submucosa membrane plays an important role in the appearance of proton conductivity.
