[47]. 11 Synthesis route of oligomeric polyurethane with terminal phosphorous choline groups. Reprinted with permission from Ref. [52]. 11) [52,53]. The key to preventing protein adsorption is to have phosphorous choline groups at the polymer surface. To achieve this goal, PU–FPC is synthesized by putting fluorocarbon and phosphorous choline groups together because fluorine has a much lower surface energy and has a great tendency to concentrate at Surface characterization techniques 33 the polymer/air interface.

In theory, XPS can detect all elements. However, H and He are barely detected in practical ­situations [46]. Chemical bonding or chemical state plays an important role in the binding energy of the electron orbital and thus gives rise to observable energy shifts in the kinetic energy of the photoelectron. These binding energy shifts can be used to extract information of a chemical nature (such as atomic oxidation state/chemical bonding) at the sample surface. aspx). 4)). When the ample surface is irradiated by X-rays, the X-rays knock out outer electrons on the surface.

1 Static sessile drop A typical static sessile drop is created by a microsyringe with an automated plunger to place a tiny drop of water on the polymer surface. Ideally, the polymer sample should be in a humidity chamber to minimize the water evaporation that would change the shape, and thus the CA of the droplet. The shape of the droplet is captured by a camera and CA is measured by an image analysis software [30]. 2 Dynamic contact angle Polyurethane is a segmented polymer with both a hard segment (diisocyanate/ chain extender crystalline region) and a soft segment (polyols amorphous region).
