Hierarchical Assembly of TiO2 Nanoparticles on WS2 Nanotubes Achieved Through Multifunctional Polymeric Ligands

subject

description

Thefunctionalization of nanotubes is required in order to bene-fit from their outstanding properties, as any application inmaterials and devices is hindered by processing and manipu-lation difficulties. Only the attachment of appropriate chem-ical functionalities on the nanotube surface allows tailoringof the properties for the respective applications. As an ex-ample, the enhancement of the nanotube solubility is onemajor task since most pristine nanotubes are insoluble inboth water and organic solvents. Thus, the improvement ofthe solubility by chemical functionalization is an importantconcept for synthetic chemists and materials scientists. Tai-loring of the surface chemical bonds might also lead to anoptimized interaction of the nanotubes with solvent mole-cules, polymer matrices, or biomolecules. Furthermore, thefunctionalized nanotubes might reveal mechanical or electri-cal properties that differ from those of the pristine ones. Fi-nally, the attachment of nanoparticles to one-dimensional(1D) nanostructures offers great potential for their use asbuilding blocks for applications in nanoelectronics
