Sep 07, 2015 · However, it remains challenging to form layers of <20 nm with high zwitterion content on the surfaces with different degrees of hydrophilicity. We demonstrate that amine-functionalized sulfobetaine (SBAm) can be co-deposited with dopamine on ultrafiltration (UF) membranes, leading to a thickness of 10 nm to 50 nm and an SBAm content of up to 31 ...

and thus zwitterionic property, are wcfR, which encodes a pro-tein that synthesizes AATGal, and wcfS, which encodes a GT that transfers this amino sugar to the polysaccharide backbone, in an adjacent position to wcfR (Figure 1)(Coyne et al., 2001). Gene homologs to wcfR and wcfS downstream of upaY and

Apr 15, 2015 · The molecular structure of zwitterionic polyurethanes was investigated with ATR-FTIR and XPS ().The broad shoulder at 3318 cm −1, corresponding to N–H stretching vibration and the characteristic carbonyl peaks at 1688 cm −1, indicates the formation of urethane linkages in all MZPU (Fig. 1A). The peak appearing at 1038 cm −1 suggests the presence of SO 3 − …

zwitterionic polymer to a hydrophobic molecule or domain. A mixed solvent system may partially synthesis of zwitterionic polymer surfactant, a hydrophobic precursor for superhydrophilic zwitterionic polymer has been used (i.e., CB-tBu in Fig. 2A).
