Superhydrophilic polymer surface

Because the polymer surface reorients the hydrophilic groups toward polymer/water interfaces, modified polyurethanes show much lower CA after hydration (Table 2.1). PU-PEG IK-OH, PU-PEG IK-NH2, and PU-PEG IK-SO3H show complete wetting (undetectable 6(ec) after hydration, suggesting a superhydrophilic nature of the modified surfaces. The hydrophilic surface modifications greatly reduced Escherichia coli adhesion. 

In this chapter, recent developments on different polymer surfaces with superwettability will be introduced. As mentioned above, the super-wettability on a solid surface is not solely determined by the chemical composition of that surface, but is also a result of some roughness arrangement. Theoretically speaking, all polymers can be either made superhydrophilic or superhydrophobic with the help of proper surface structures. As a result, it is...
