Multiscale approach to the morphology, structure, and segmental dynamics of complex degradable aliphatic polyurethanes

Popis výsledku v původním jazyce

A multiscale approach spanning from the segmental (subnanometer) up to micrometer level was applied for detailed study of the self-assembly of aliphatic block polyurethane (PU) elastomers. To understand the principles of the self-organization of hard andsoft segments in the complex multi-component systems, several two-component model PU samples, that is, the products of 1,6-diisocyanatohexane (HDI) with three diols differing in the length and constitution were also prepared, characterized, and investigated: (i) polycarbonate-based macrodiol (MD), (ii) biodegradable oligomeric diol (DL-L; product of butane-1,4-diol and D,L-lactide), and (iii) butane-1,4-diol (BD). The study (particularly 13C-1H PILGRIM NMR spectra) reveals complex internal organizationand interesting (application appealing) behavior of multi-component PUs. Hard segments (HDI+BD products) feature self-assembled and significantly folded chain conformations with interdomain spacing 15?22 nm (small-angle X-ray scattering
