Molecular origin of stress softening in elastomer-based nanocomposites via in situ elongational nuclear magnetic resonance spectroscopy

Abstract Understanding the molecular origin of stress softening in silica-reinforced polydimethylsiloxane remains a challenge. Here, we apply in situ elongational nuclear magnetic resonance (NMR) spectroscopy to selectively probe the polymer matrix under deformation. This allows us to address two ke...
