Extended Data Fig. 2 | Rheology of silica aerogel inks. a–d, Apparent
viscosity as a function of applied shear rate (a, c), and storage (G′) and loss (G′′)
modulus as a function of applied shear stress (b, d), for the silica aerogel ink
with various loadings of silica aerogel particles (as labelled). e, f, Shelf life of ink
SP1.6: apparent viscosity as a function of applied shear rate (e), and storage (G′)
and loss (G′′) modulus as a function of applied shear stress (f), for the fresh
silica aerogel ink and after 30 days of storage at room temperature (25 °C, 50%
relative humidity).
