A novel nanocage from the cooperative self-assembly of coil-rod-coil triblock copolymers and nanopartilces

A Dissipative particle dynamics (DPD) simulations are performed to study the cooperative self-assembly of coil-rod-coil triblock copolymers and nanoparticles in solution. The results show that, when the nanoparticle concentration exceeds a given value, the ternary systems can form a novel nanocage composed of two-end coil-caps and middle rod-linkers. The novel nanocage is very similar to the real bird cage and the captured nanoparticles like the bird. It is the first nanocage from the self-assembly of coil-rod-coil triblock copolymers. This may be used for the release of drugs and fertilizers, or as nanoreactors. This novel "nanocage" formed by the cooperative self-assembly of coil-rod-coil triblock copolymers enriches the material source of the nanocage. The novel structure is may be used to the release of drug and fertilizer, or the nanoreactors.
