These studies showed the presence of homogeneously
dispersed carbon nanoparticles within the cellular structure of the
foams through a careful analysis of the rheological properties
[18,19]. In the present work, we study the effect of the carbon
nanostructures in the matrix phase-separated block copolymer
morphology, since it has a profound effect on the final properties of
the foam. Hence, we select a fixed loading fraction and two
different contents of hard segments and analyze both the kinetics
of polymerization and the kinetics of matrix morphology development.
The reaction kinetics of PU nanocomposites foams is
monitored by FT-IR spectroscopy while the matrix morphology
development is investigated by synchrotron SAXS. Visual 3D
representations of the PU morphologies are generated from the
SAXS data. Finally, the effect of the carbon nanofillers on the phaseseparated
morphology is analyzed by AFM.
