摘要

Multi-walled carbon nanotubes functionalized with F3C-(CF2)(5)-(CH2)(2)-SiCl3, a molecule bearing a fluorinated terminal group is found to favor the carbon nanotubes dispersion in three perfluoropolyether fluids (Galden (R) SV70, Fomblin (R) Y25 and Fomblin (R) YR1800). The stability of the suspension appears to be related to the perfluoropolyether viscosity. With respect to time, Fomblin (R) YR1800, the more viscous fluid, leads to the most stable solutions, followed in order by Fomblin (R) Y25 and Galden (R) SV70, In general the smallest particles stay in suspensions. Stability extending over more than one year is observed in the case of Fomblin (R) YR1800.
