| Research Abstract |
The aims of this study are the construction of carbon nanotube-based hybrid nanomaterials. The combination of carbon nanotubes and organic, inorganic and polymer materials may lead to the construction of navel nano carbonmaterials with high performances. The obtained results are summarized as follows.
Carbon nanotubes are found to dissolve individually insolvents containing several kinds of amphiphiles carrying an aromatic moiety including anthryl, phenathryl and pyrenyl groups. The sollubilized nantube solutions were characterized by NMR, UV vis-near IR and Raman spectra.
We have introduced an aromatic moiety to poly(styrene-alt-maleic anhydride). The synthesized copolymers were characterized by atomic force microscopy, UV-vis-near IR,NMR and Raman spectra and found that they act as "reactive carbon nanotube solubilizers" that should be useful for the design and construction of SWNTs/polymer composite nanomaterials with specific functions.
We have already reported that double-stranded DNA dissolves SWNTs in aqueous solutions. DNA/carbon nanotube films were successfully formed by the alternating adsorption of poly(dC)-SWNTs and poly(dG)-SWNTs onto a quartz substrate. UV-vis-near IR spectra for the obtained DNA-SWNTs films showed absorption bands in the region of 500-600nm and 1000-1400 nm that are assignable to met-SWNTs and sem-SWNTs, respectively. The DNA-SWNTs films after the adsorption cycle of 50 times showed characteristic Raman peaks derived from the SWNTs on the substrate.
