Nonfouling biomaterials based on polyethylene oxide‐containing amphiphilic triblock copolymers as surface modifying additives: Adsorption of proteins from human plasma to copolymer/polyurethane blends

Three polyethylene oxide-polyurethane-polyethylene oxide (PEO-PU-PEO) block copolymers of variable PEO block size (MW 550, 2000, and 5000) were used to modify the surface of a conventional segmented polyurethane (PU) with the objective of inhibiting interactions with proteins. The surface-active copolymers were blended with the PU by solution methods. Protein adsorption from human plasma to the modified materials was investigated using …
