摘要： The biocompatibility of polymeric and metallic articles used in contact with blood can be substantially improved by coating the articles as described. The coating materials are triblock copolymers of the polylactone-polysiloxane-polylactone type. Optimum biocompatibility is provided by a coating of optimum surface concentration. Porous membranes can be coated as described, providing improved biocompatibility of blood oxygenators, hemodialyzers and the like.

摘要： The surface free energy of a polymer blend where a base polymer contains an additive having a different surface free energy than that of the base polymer can be controlled over a wide range of additive surface concentrations by appropriate choice of the mold surface free energy during fabrication. A high surface concentration of additive relative to a low bulk concentration can be achieved, leading to improved biocompatibility without loss of optical clarity.
