A highly stretchable dielectric elastomer based on core–shell structured soft polymer-coated liquid-metal nanofillers. Issue 78 (1st September 2020) - Su, Yaotian
Abstract : We report a facile and scalable approach for synthesizing soft nanofillers based on liquid metal nanodroplets with poly( n -butyl methacrylate) (PBMA) coating layers, thereby producing a sort of dielectric elastomer with super stretchability. Abstract : Elastomer, poly( n -butyl methacrylate), coated liquid metal (LM) nanodroplets (EGaIn@PBMA) were successfully fabricated via a facile in situ free radical polymerization method. The as-prepared soft nanoparticles can be directly hot-pressed into nanocomposites which not only exhibited ultra-high stretching flexibility (>400%) but also excellent dielectric properties with remarkably suppressed dielectric loss, showing great promise in the flexible energy-storage field.
