Towards crack-resistant nanoparticle-based latex films: Scientists leverage a novel polymer interlocking mechanism to produce tough yet additive-free latex films

Synthetic latex films are widely used across many fields, but they usually contain harmful additives to enhance their strength. In a recent study, researchers have developed a new class of latex films composed of rotaxane-crosslinked acrylic nanoparticles. These films exhibit remarkable mechanical properties, including excellent crack-propagation resistance without any additives, and are easily recyclable, paving the way for more environmentally friendly materials.
