Paper Abstract

On the basis of the relation of polymer free volume and the stress and strain, a novel image measurement with computed digital tomography was developed for the polymer morphology during extrusion in the paper. The method synthetically utilizes the knowledge of nuclear physics, photo-electricity, polymer physics, computer technology and mathematics, the dynamic deformation and morphology of polymer can be visually obtained by the interaction of the atom of polymer or polymer chain and the photon beam to come from gamma ray, in which the photoemission, Compton effect and electron pair effect will be generated. The experimental result indicates the method can not only measure the dynamic deformation and morphology of extrusion polymer in the way of non-open, non-destroy and on-line, but also deduce the relationship between the mechanical properties and polymer morphology during extrusion.
