Abstract


Nano-materials and nano- structures is an important object of study in the field of new materials today , especially nanomaterials today's nanotechnology research hotspots due to their novel physical , chemical and biological characteristics and potential use in nanoscale devices . In this thesis in the team original work based on , to produce soluble, easy processing organic - inorganic composite nanomaterials application target , choose to have their own discussion group to study characteristics of CNTs / CdS core-shell nano- wire structure as inorganic material , poly anisole dendrimers with a mercapto group as an organic solubilizer , polyethylene anisole dendrimers by a mercapto group to the chemical action of the CNTs / CdS core - shell nanowires , improved core - shell nanowires in common organic solvents solubility, provides the basis for the wet processing of the material , and opens up a new approach is also similar to the application of nanomaterials . The main works are summarized below: 1. Inward convergence method , protection, deprotection methods , 3,5 - dihydroxy benzoic acid for the synthesis of branched units two polyether dendrimers thiol molecules with alkyl chains , its structure was characterized by infrared spectroscopy and NMR . 2 to CNTs nanowires as a template , simple , moderate room temperature oxidation to restore hair preparation of functionalized CNTs / CdS core-shell heterostructure nanowires , confirmed its structure through a variety of characterization methods , TEM pictures clearly to show that the presence of a core - shell structure , EDX given the presence of these elements of the Cd, S, C , the XRD pattern proof shell of CdS hexagonal . 3 with a mercapto group poly anisole dendrimers and CNTs / CdS core-shell nanowires role in an organic solvent , by adjusting the reaction time and temperature , was successfully prepared a soluble form of CNTs / CdS core - shell nanowire structure . The solubility experiments clearly showed peripheral modifier effective in improving the CNTs / CdS core - shell nanowires solubility in an organic solvent , the XRD test results show that the peripheral organic modification does not affect the internal structure of the CNTs / CdS core - shell nanowires .
