Real-time crystallization of organoclay nanoparticle filled natural rubber under stretching

An experimental evidence of a remarkable enhancement of strain-induced crystallization in natural rubber nanocomposite under uniaxial stretching, due to the presence of nanoclay particles, is described. Synchroton wide-angle X-ray diffraction (WAXD) have been used to monitor structure changes and cr...
