Figure 5. Composites exhibit pronounced viscoelastic properties which vary with actin fraction.

Figure 5.

(A) Storage and (B) loss moduli, G’(ω) and G”(ω), are plotted vs. frequency (ω). (C) The complex viscosity η*(ω) vs. ω is plotted. (D) The zero-shear viscosity, η0, (left axis) and the average storage modulus, <G’(ω)>, (right axis) are plotted vs. actin fraction. While increasing the fraction of actin within the composite generally serves to increase the viscoelasticity, there is relatively little change in η0 and <G’(ω)> between the φA = 0.25 and φA = 0.5 composites.
