Examination of Hard Segment and Soft Segment Phase Separation in Polyurethane Medical Materials by Electron Microscopy Techniques
Published online by Cambridge University Press: 09 December 2005
Abstract
A combination of transmission electron microscopy (TEM) and in situ tensile testing in an environmental scanning electron microscopy (ESEM) was used to evaluate the static bulk and dynamic surface morphologies of medical polyurethanes. TEM results showed phase-separated hard segment and soft segment structures. Surface morphology as a function of strain was studied using ESEM in conjunction with a tensometer.
