Abstract

---

Pristine Multiwalled Carbon nanotubes (MWNT) were dispersed in two selected surfactants and their mixture using a probe sonicator at room temperature. The results presented in this article apply only to the short-length MWNT. The dispersions achieved generally ranged from very poor to average. In the average category, the solvents ranked o-Dichloro benzene > Dimethyl formamide > Tetrahydrofuran. The surfactants and one of the mixtures performed better than average with Sodium lauroamphoacetate (Miranol) > Cetyl pyridinium chloride (CPC) > Miranol/CPC mixture (50:50). The higher the aspect ratio, the more difficult they are to disperse; the shorter the nanotubes, the better and more uniform the dispersion obtained. Miranol was then applied (dyed) on Polyester fabrics and various chroma Characteristics obtained.
