Aerogel-involved triple-state viscoelastic fluidic materials enable high-efficiency dual-purpose energy management (opens in new tab)

Fluidic materials remain in their infancy. Here, we develop triple-state fluids (TSFs) by dispersing superhydrophobic aerogel microparticles into aqueous solutions, creating multiphase systems that integrate solid, liquid, and gaseous states with heterogeneous lyophobic characteristics and dual-mode viscoelasticity. TSFs exhibit low density (0.45 g·cm−3), low thermal conductivity (0.21 W · m−1 · K−1), and a shear viscoelasticity that shifts from the solid-like to the liquid-like in response t...
