A polymer surface with excellent blood compatibility has been produced via spontaneous surface segregation of a block copolymer. The water‐soluble polymer block (PME3MA) spontaneously segregates into hydrophobic and hydrophilic environments (see Figure), causing the blocks to expel biological substances including proteins, cells and platelets via flexible chain motion.
