abstract = "in this study, in situ polymerization procedure in solvent mixture was used for the preparation of thermosetting PU nanocomposites (PUNCs) with different content of soft segment (from 30 to 60 wt%), and with the addition of organomodified montmorillonite clay (Cloisite 30B®) as the nanofiller, in an amount of 0.5 wt.%. The PUNCs were based on poly(dimethylsiloxane) macrodiol (PDMS) that represents soft segment and 4,4′-diphenylmethane diisocyanate (MDI) and hyperbranched polyester (BH-30) which were selected as the hard segment. The PUNCs are marked.
so that the last two numbers in title indicate wt.% of soft segment in materials. Namely, the main
objective of this study is to analyze the effect of the soft segment content on the morphology of the
prepared PU nanocomposite films using atomic force microscopy (AFM), scanning electron
microscopy (SEM), and small- and near wide-angle X-Ray scattering (SWAXS) analyses. SEM
images of the fractured surfaces were obtained on JEOL JSM-6610LV. AFM analysis was carried
out by atomic force microscope (Dimension Icon, Bruker, USA). SWAXS measurements of the
PUNCs were performed using SAXS instrument (originally Molecular Metrology, USA, recently
considerably upgraded by SAXSLAB, now Xenocs).",
