Synthesis and Self‐Assembly of Pore‐Forming Three‐Arm Amphiphilic Block Copolymers
A novel two‐step synthesis of an amphiphilic three‐arm block copolymer and self‐assembly and its tendency to pore formation is presented. Self‐assembly in the bulk state is investigated using TEM and SAXS. Pore formation following a SNIPS protocol is studied using SEM. The porous structures are further investigated via AFM in air and water.
