Abstract
Deformation mechanism of dry gel polyethylene film which can be elongated to a draw ratio of λ=300, was investigated in terms of morphological aspect by scanning electron microscopy, polarized microscopy, small angle X-ray scattering, wide angle X-ray diffraction, and small angle light scattering. Through a series of experimental results, the morphology of the dry gel films is found to be similar to that of single crystal mats and then the facile drawability is thought to be due to the transformation from a folded to a fibrous crystals. In this process, a suitable level of entanglements between crystal lamellae plays an important role to transmit the drawing force as intermolecular crosslinks.
