Spontaneous Formation of Blood‐Compatible Surfaces on Hydrophobic Polymers: Surface Enrichment of a Block Copolymer with a Water‐Soluble Block

Abstract

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.
