Study on the Construction of TATB @ ES /Al Composites via Interface Regulation and Their Hydrophobic Properties

ABSTRACT TATB features a surface architecture rich in intermolecular hydrogen bonds, which inherently leads to poor interfacial compatibility with nano‐Al and pronounced hydrophilicity, severely limiting its application. Herein, a mild solvent‐evaporation strategy was employed to fabricate TATB@ES and TATB@ES/Al energetic composites using thermoplastic polyurethane Estane (ES) as an interfacial mediator. At only 1 wt% loading, ES formed a conformal hydrophobic interlayer that preserved the prist
