제목 Recovery of multiwall carbon nanotube waste using chemical bond with alkane dithiol
초록 Multiwall carbon nanotubes (MWCNT) were assembled into strands by cross-linking with alkane dithiols. Long MWCNT strands (1-10 um) were shortened to 0.25 um by chemical oxidation followed by ball-milling, and then thiolated by reaction with cysteamine. The thiol groups on the surfaces of the MWCNT strands combined with Au nanoparticles to produce MWCNT–AuNP strands. A simple mixing of these strands with alkane dithiols resulted in an assembly of strands linked by the alkane dithiols which adsorbed onto the surfaces of the AuNPs attached to the MWCNT–AuNP strands. Short MWCNT–AuNP strands connected to one another in a parallel arrangement, whereas long strands assembled in a crossing arrangement. The possibility of using this method to chemically bond MWCNTs to collect forming the lump of MWCNTs waste is discussed.
