The presorted samples avg., length 704 nm, 987 nm, and 3360 nm demonstrate an amorphous "gel-like" structure, while the shorter length SWNT composites of 638 nm and below demonstrate a crystalline structure.
Dynamic viscosities of presorted nanotubes-PIB mixtures, at multiple weight fractions, are shown in Figure 7, and the dynamic viscosity at frequency 0.1 rad/s was recorded in Table 4 as the final viscosity value for further discussion.
In contrast, the 3360 and 987 nm length SWNT samples have smaller dynamic viscosity while those of presorted nanotubes (mixed lengths with avg.
The presorted samples having an average length of c.a.
Furthermore, according to Table 1, the presorted, mixed length sample has the highest concentration of longer length SWNT comparatively, which stops crystallization as discussed before.
According to Table 4, the dynamic viscosity of PIB mixed with presorted nanotubes does not increase monotonously with weight fractions, which indicates the effect of conformational change and the occurrence of non-Einstein viscosity behavior.
Furthermore, the longer length nanotube samples still result in viscosity one order larger than the pristine presorted nanotube samples.
This step removes large bundles formed during ultrasound treatment, rendering the presorted nanotube fractions.
First, aqueous solution of presorted nanotube was dropped into the mixture at various weight fractions including 0.05, 0.1, 0.25, 0.5, 1, and 5 wt.%.
