Structural Investigations of Polyurethane-Urea∕Clay Nanocomposites (original) (raw)

2011

Abstract

Structural features of polyurethane-urea (PUU)/organoclay nanocomposites have been investigated by FTIR and small angle x-ray scattering techniques. It is found that the clay has significant influence on morphology of the hard segments (HS) of the PUU. The HS domains which have rough surface, becomes more compact with mass fractal morphology with increase of clay content. FTIR suggests the clay interacts
