Rupture stress of liquid metal nanoparticles and their applications in stretchable conductors and dielectrics

Abstract Few works had systematically investigated the relationship between the rupture stress of the oxide shell and the diameter of liquid metal nanoparticles (LMNPs). Here, we fabricated a series of elastomer/LMNPs composites, which were based on various polyurethanes with different shore hardnes...
