“…The relationship between the structure and properties of segmented PURs has been extensively investigated [16][17][18][19][20][21] and has been considered in relation to their biocompatibility. Many researchers have focused on protein adsorption, cell adhesion and blood compatibility of segmented PURs [22,23].…”

“…That is why the variety of their utility is so wide in medical applications. PUR have been used in a variety of medical devices such as intravenous catheters (US 5752941; US20110178507, US20100256546), vascular grafts (US20080306181, US 8187319, US20120271200 A1), cartilage replacements (US20110105635, US20080262618), artificial hearts (EP0914834 A2, US5393858, US5500016), and pacemaker lead insulation [29][30][31]. PUR chains contain hard and soft segments, which allow for subtle control of their structure and properties.…”

“…The hard, rigid segments are produced by the reaction between the diisocyanate and the chain extender, whereas polyether, polyester, or polycarbonate diol comprise the soft segments. The amount of hard segments influences the degree of phase separation, which in turn affects physical and mechanical properties [30], degradation rate and biocompatibility [32][33]. By varying the molecular weight of polyol and the composition of the different segments, properties of PUR can be tuned up for use in many areas of TE [34][35][36][37][38].…”

Abstract. The introduction of the paper was devoted to the main items of Tissue Engineering (TE) and the way of porous structure obtaining as scaffolds. Furthermore, the significant role of the scaffold design in TE was described. It was shown, that properly designed polyurethanes (PURs) find application in TE due to the proper physicochemical, mechanical and biological properties. Then the use of L-ascorbic acid (L-AA) in PUR systems for TE was described. L-AA has been applied in this area due to its suitable biological characteristics and antioxidative properties. Moreover, L-AA influences tissue regeneration due to improving collagen synthesis, which is a primary component of the extracellular matrix (ECM). Modification of PUR with L-AA leads to the materials with higher biocompatibility and such system is promising for TE applications.

“…It is used to probe the glass transitions in hard segments and soft segments [9,10]. Different forms including thermoplastic PU [11,12], caster oil-based PU [13], poly(ester-siloxane)urethanes [14] and PU foam [15] have been studied by DSC. Furthermore, the effect of metal on the glass transition of PU has been reported [16].…”

Effects of magnetic cobalt ferrite (CoFe 2 O 4 ) on thermal properties of polypropylene (PP), polyurethane (PU) and natural rubber (NR) matrices were studied by differential scanning calorimetry. The endothermic peak area of PP was reduced with increasing loading of CoFe 2 O 4 from 0 to 45 % and such peak in semicrystalline PU was entirely absent when the CoFe 2 O 4 loading was over 25 part per hundred rubber. The results indicated that magnetic clusters embedded at the interchain spacing inhibited the nucleation of order segments in polymer matrix. The presence of CoFe 2 O 4 particles also had influence on the mobile amorphous portions of PU chains with polar functional group. No endothermic evidence on the thermograms of non-polar amorphous NR was observed.
