Popis: We report the sonophysically-exfoliated methods access to the preparation of homogeneous-free multi-walled carbon nanotubes (MWCNTs) in water solution. Highly stable, uniform, individual MWCNTs are entirely performed through sodium dodecylsulfate surfactants by means of a tip sinicator. HRTEM images show that the crystalline finger walls of individual CNTs are apparently observed. Raman spectrum of MWCNTs shows that the so-called G'-band, associated with metallic electronic structure, was significantly observed at 2644 cm -1 with full-width at half-maximum of 262 cm -1 , indicating that the sonication physical methods do not alter their electric properties. Owing to its easy-to-use procedure and low cost of implementation, this approach could lead to the commercial viability of the large-scale MWCNTs processing.
