The morphology and physicomechanical properties of two types of collagen membranes, one of which does not have telopeptides, were compared with small‐angle light scattering, rheo‐optical, dynamic mechanical, and dynamic rheo‐optical techniques. The presence of telopeptides in native collagen allows the formation of larger rod‐like superstructures; it renders the membrane more resistant to irreversible deformation yet more responsive to dynamic mechanical perturbation. Telopeptides are also responsible for relaxation at room temperature, and impart more linearly elastic properties to the material as compared to membranes derived from enzyme‐treated collagens.
