Viscoelastic properties of MC. (A) Frequency sweep at 37°C for MC at different concentrations (0.8% to 2.5%). Curves are representative of 3 different samples for each concentration. G′ (filled symbols) and G″ (unfilled symbols) represent the elastic and viscous parts, respectively, of the complex shear modulus and are both expressed in Pascals. (B) Evolution of the shear modulus over 3 days in 2% MC (left) and 2.5% MC (right) at a constant oscillatory frequency.
