The dielectric relaxation time of collagen over a wide temperature range
- 65 Downloads
The dielectric properties of collagen were measured at two hydration levels over a frequency range of 101–105 Hz and at temperatures from 298–470 K. In the low-frequency range, dielectric dispersion was observed which results from Maxwell-Wagner-Sillars polarization. The relaxation times for a collagen sample containing loosely bound water were shorter than for a collagen sample containing only structural water in the temperature range 298–390 K. Above 390 K, continuous decrease in the relaxation times was observed for both samples.
