Modification of PU with functional groups

Kim et al. reported an investigation into the negatively charged surface of a PU with a sulfonated PEO graft. They described the importance of the flexible PEO chain on the antithrombogenicity using a negative cilia concept [58,59]. [Pg.325]

PhosphorylctK ine (PC) group takes internal salt structure stably with 6-alo ms ring structure. [Pg.325]

In the field of biomimetic chemistry, phospholipid molecules have been utilized for the preparation of cell membrane-like stractures, namely, liposomes and Langmuir-Blodgett membranes. However, a major disadvantage of molecular assemblies of this kind is their inadequate chemical and/or physical stability. Stabilization of the phospholipid assembly is therefore an important topic of focus in the construction of interfaces between living and artificial systems. One approach to addressing this issue is the design of a new type of polymer system with PC groups. [Pg.326]

Several studies that involve the introduction of PC groups to a PU surface have been performed. They are summarized in Table 11.1. [Pg.326]
