It is commonly believed that block copolymers are the only type of polymeric surfactants available for incompatible homopolymers( 1 ). We explore the conditions for which a homopolymer will also lower the surface tension between two incompatible homopolymers by lowering the enthalpic contribution to the interfacial free energy, noting that the resulting three‐component interface will not necessarily have the same mechanical strength as a block copolymer‐homopolymer interface.
