A series of well-defined MMA-DMA-MMA triblock copolymers with different molecular weights and compositions were synthesized by in situ sequential block copolymerization of DMA followed by MMA from a difunctional initiator through Ru-based living radical polymerization. Obtained triblock copolymers showed periodically well-organized morphologies both in bulk and in film states, giving excellent actuation performances at relatively lower electric fields due to their polar methacrylate groups (k), lower modulus, and microstructures.
