Figure 3: Rheological properties of composite inks.
From: Shape-morphing composites with designed micro-architectures
(a) Ink viscosity dependence on CNF concentration for viscosity at a shear rate of 1 s−1 showing shear thinning behavior. (b) Ink storage modulus as a function of shear stress for low, medium, and high CNF concentrations, which shows the onset of a yield stress at medium CNF concentrations. (c) Ink storage modulus dependence on CNF concentration for storage modulus at a shear stress of 1 Pa in the plateau regime. Increasing CNF concentration increases the ink storage modulus over 3 orders of magnitude.
