Abstract Polyethylene terephthalate (PET) is the most widely used polymer in world. For first time, laser‐driven integration of aluminum nanoparticles (Al NPs) into PET to realize a laser‐induced graphene/Al NPs/polymer composite, which demonstrates excellent toughness and high electrical conductivity with formation carbide shown. The conductive structures show an impressive mechanical resistance against >10000 bending cycles, projectile impact, hammering, abrasion, structural chemical...
