With the support of the National Natural Science Foundation of China and the Chinese Academy of Sciences, researchers in the Key Laboratory of Colloids, Interfaces, and Chemistry and Thermal Engineering have made new advances in the controllable assembly of nanostructures and their applications. The relevant research work was published in the recent "Advanced Materials". (2008, 20, 452-456).
In recent years, the research group has been devoted to the controlled assembly of functionalized nanomaterials and nanostructures, and has applied them to various fields and achieved a series of results. In terms of assembly of polymer nanotubes, light-emitting composite nanotubes with good flexibility and electro-optical functions (Chem. Eur. J. 2006, 12, 4802) were prepared and applied to cells by means of a layer assembly technique and a template method. Gene-transfected biodegradable nanotubes (Biomaterials 2007, 28, 3083); Grafted and assembled pH using surface-initiated Atom Transfer Radical Polymerization for controllable preparation and assembly of smart nanoparticle/polymer composite structures And thermally responsive core-shell composite nanostructures (Chem. Mater. 2007, 19, 412, Chem. Eur. J. 2007, 13, 2224; Adv. Funct. Mater. 2007, 17, 3134).
Based on the above research work, the research group used crystal-constrained diffusion growth to controllably prepare a reactive crystal template MnCo3, combined with the Kirkendall effect, to achieve controlled preparation of hollow MnO2 with different shapes, different wall thicknesses, and hierarchical nanostructures. The three-dimensional assembly of nanomaterials and nanostructures and their regulation provides an important approach, and experiments have confirmed that the assembled hollow spheres and cubic structures of nanomaterials can be used for wastewater treatment containing organic dyes.
