在101- 105 Hz的频率范围和298-470 K的温度下，在两个水合水平下测量胶原的介电性质。在低频范围内，观察到的介电色散的结果从麦克斯韦-瓦格纳-Sillars极化。在298-390 K的温度范围内，含有松散结合水的胶原样品的弛豫时间比仅含有结构水的胶原样品的弛豫时间短。高于390 K，连续减少的弛豫时间观察到的两个样品。
The dielectric properties of collagen were measured at two hydration levels over a frequency range of 101–105Hz 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.
