Flame‐Retardant Expandable Graphite–Polymer Composite Putty for High‐Temperature Triboelectric Nanogenerators and Shape‐Adaptive Cyclic Fire‐Warning

Advanced Functional Materials, EarlyView.
This work introduces shape‐adaptive, flame‐retardant (FR) expandable graphite–filled polymer composite putty that unites moldability, self‐healing, adhesion, conductivity, and exceptional fire‐shielding performance to enable FR–TENGs and cyclic fire warning systems operable on complex and irregular 3D surfaces. ABSTRACT Self‐powered, flexible, and fire‐
