Abstract With their low density and high porosity, aerogels are widely used as supporting frameworks for phase change materials (PCMs). However, the host–guest solid–liquid phase‐change systems often encounter difficulties in optimizing balance between mechanical properties thermal energy storage performance, intrinsic advantages of not being fully realized. Herein, an aerogel‐functionalization‐PCM strategy, a completely converse route compared to traditional aerogel‐filling‐PCM method, toward lightweight, flexible PCM robust management is developed. As proof concept, silica aerogel particles (SAPs) functional components added polyvinyl alcohol‐polyethylene glycol network produce composite PCMs. The addition SAP reduces PCM's latent heat by 25% but significantly decreases heating rate 190% enhances insulation 147%, achieving 28 °C temperature drop at 80 °C. This work provides fresh perspective on design thermally PCMs demonstrates feasibility enhancing protection under reduced conditions.
