Organic-inorganic nanocomposites composed of polymer and nanoparticles offer a vast design space of potential material properties,depending heavily on the properties of these two constituents and their spatial arrangement.The ability to place polymers in direct contact with functional nanoparticles via strong bonding,that is,stable chemical interaction without the dissociation of surface capping polymers,provides a means of preventing nanoparticles from aggregation and increasing their dispersibility in nanocomposites,and promises opportunities to explore new properties and construction of miniaturized devices.However,this is still a challenging issue and has not yet been largely explored.
