Our group envisioned to make poly(styrene-block-ethylene oxide) block copolymer which can be cleaved by electrolysis. These new materials, along with their well-ordered self-assembly, can be applied to a wide range of nano technologies such as nano-structure fabrication, separation membranes, and sensors. To synthesize the desired block copolymer with well-defined molecular weight and functionalities, we employed the atom transfer radical polymerization (ATRP) technique. As for the electrolytically active linker between the two blocks, quinone type fragments were introduced. This block copolymer was successfully cleaved by electrolysis in acetonitrile/water (9:1) under 2.0 V. The removal of PEO domains from the PS-b-PEO was verified by various analytical tools such as 1H-NMR, GPC, AFM, SEM and TEM. |
