Recently,many studies have been carried out on the cooperative self-assembly of block copolymer and inorganic nanoparticles,which offers a way to create solution processable functional materials with useful chemical and mechanical properties of polymers and nanoparticles.1 Researchers have made a number of effects toward encapsulating different types of nanoparticles into aggregates of block copolymers with controllable nanoparticle arrangements and morphologies.2 However,most of the block copolymers used in previous work are coil-coil block copolymers,rod-coil block copolymers are rarely applied.
