Block Copolymers at Homopolymer Interfaces: Conformation and Compatibilization is a recent paper published in Macromolecules. In this work by Zhan Chen,* Christian Steinmetz,* Mingqiu Hu,* E. Bryan Coughlin,* Hanyu Wang, William T. Heller, Wim Bras, and Thomas P. Russell*, researchers demonstrated the interfacial broadening by adding star block copolymers as compatibilizers and investigated their architectural-directed interfacial conformation. We also proved star block copolymers serve as a more efficient compatibilizer compared to their linear counterparts towards polymer upcycling.
