Abstract

Supramolecular structures and morphologies of nonsintered, sintered, and radiation-modified suspension-polymerized PTFEs are investigated via scanning electron microscopy. Gamma irradiation is performed below and above the melting point of the crystalline phase. The fibrillar supramolecular structure of the nonsintered PTFE is preserved after its sintering. However, some regions of fibrils in the sintered PTFE form lamellas elongated perpendicularly to the orientation of fibrils. Irradiation of PTFE below the melting temperature at 20 and 200°C is not accompanied by a qualitative change in its morphology. Irradiation above the melting temperature results in reorganization of the PTFE structure, namely, formation of spherulites consisting of radially oriented fibrils.
