Physicochemical and biological characterization of nanocomposites made of seg…

Nanocomposites were prepared with segmented polyurethanes and Cloisite 30B by either solution mixing or in situ polymerization and characterized by Fourier transform infrared spectroscopy, differential scanning calorimetry, thermogravimetric analysis and X-ray diffraction. Cytotoxicity and enotoxicity were assessed with lymphocytes while cell viability was measured by the methyl tetrazolium ass…
