Effects of a Pseudophysiological Environment on the Elastic and Viscoelastic Properties of Collagen Gels

Figure 8

Relaxation times of ring-shaped collagen gels as a function of temperature (experiments performed either at 23°C or 37°C), hydration (either with or without a PBS solution), and mechanical preconditioning (either with or without mechanical preconditioning PC). and are the relaxation times of the gels considered in the viscoelastic model. Values are expressed as mean standard error. Significance: * ; ** ; *** .
