Low‐Outgassing Liquid Metal–Silicone Composites for Multifunctional Space Applications

Advanced Materials Technologies, EarlyView.
Integrating liquid metal microdroplets into a space‐grade silicone creates a multifunctional composite while preserving its inherent flexibility and low‐outgassing behavior. The composite has 11×$\times$ higher thermal conductivity while remaining thermally stable and maintaining a total mass loss of ≤$\le$ 1% under thermal vacuum testing.
