The surface structure and surface mechanical properties of low- and high-density polyethylene were characterized by atomic force microscopy (AFM) as the polymers were stretched. The surfaces of both materials roughened as they were stretched. The roughening effect is attributed to deformation of nodular structures, related to bulk spherulites, at the surface. The surface-roughening effect is completely reversible at tensile strains in the elastic regime and partially reversible at tensile… CONTINUE READING
