Triblock copolymer, Poloxamer 407 or commercially known as Pluronic F127, was used for dispersing Single-walled Carbon Nanotubes (SWNTs) in aqueous solution. Due to strong van der Waals interaction between tubes, SWNTs experienced hydrophobicity properties and required surface modification. Non-covalent method of dispersing SWNTs using Pluronic polymer has the advantages of maintaining the instrinsic properties of SWNTs structure. In this study, the physicochemical properties of carbon nanotubes were analyzed in terms of size, surface modification, stability and concentration. The SWNT dispersion prepared by using probe sonication method exhibited good stability with average CNT diameter and length of 4±2 nm and 100-600 nm, respectively. The dispersion stability and hydrodynamic size were also discussed. Raman analysis was carried out in order to analyze diameter, chirality, and purity. High frequency tangential T modes or known as G band can be observed at 1591 cm-1 which represent semiconducting SWNT. Exfoliation of SWNT bundle into individual tubes was observed using SEM dan TEM.
