Polarization phenomena in collagens from various tissues

A comparative study of polarization phenomena in collagens extracted from various tissus (tendon, skin, cartilage) is presented. For this investigation, the ThermoStimulated Current (TSC) technique has been used. A special attention has been paid to dipolar reorientations associated with intra molecular mobility which has been found to be specific of the typical collagen and of its interaction with the other constituants of the organic matrix.
