Abstract
Thermally stimulated current (TSC) of tsuga (Tsuga sieboldii CARR) in Cellulose I has been measured for the fiber and tangential directions in the temperature range from −20-°C to 200°C. Three peaks A, B, and C for the fiber direction are observed at about 30°C, about 85°C and about 160°C, respectively. The peaks A and B appear for the tangential direction. The TSC currents Imax of the peaks A and B are proportional to the thickness of the sample, and increase with the polarizing field in the relation of the sine-hyperbolic equation. The peaks A and B are considered to be due to ionic space-charge polarization caused by the migration of mobile ions between neighbour-sites and next neighbour-sites of the long period with hopping.
