A team from the Nelson and Craig labs use a 1 : 1 substitution of cyclobutane-based mechanophores as scissile covalent crosslinks in 3D printed poly(methoxyethylacrylate) networks to enhance the material toughness without compromising stiffness. These crosslinkers increased the material's toughness in tensile and tearing tests without altering its stiffness or appearance, suggesting that mechanophores offer a promising route to toughen 3D printed elastomers.
