“…Different from the spherical particles which frequently caused a viscosity slight increase or even reduction when few particles (usually D < 10 nm) are introduced, the large aspect ratio of CNTs, beneficial to form networks, should be responsible for the viscosities increase presented herein. This is consistent with the suggestion that for rod‐like particles of aspect ratio ≫ 1, their nanocomposites viscosity drastically increase with the filler content . When aspect ratio increases, effective volume fraction also increases, leading to the increase of the friction between them as well as the increase of energy dissipation; thus, higher melt viscosity is obtained.…”

The rheological behavior of polymeric nanocomposites provides major determination for their processability. In this work, three carbon nanotubes (CNTs) with varied geometries were adopted as nanofiller and then were introduced into poly(methyl methacrylate) (PMMA) matrix with different loadings (0.07–1.0 wt %). The different preparation routine led to varied CNTs dispersion states, on which the shear viscosity and the compressibility of their melts were proved to be sensitive. The technology for the preparation of their nanocomposites played a crucial role in controlling their rheological behavior. With melting blended bare CNTs, the dynamic shear viscosity of PMMA/CNTs increased with the increase of CNTs content, accompanied by aggregated CNTs in which no polymer matrix was entrapped. With the help of surface modification and pre‐mixing, well dispersed CNTs were obtained and a rather low aggregation rate ca. 0.029% was revealed. The well dispersed CNTs with an organic layer which was constructed by small molecules and presented lower viscosity. Such CNTs led to no remarkable clusters within polymer host and played the role of lubricant with an increased‐mobility layer, which can be reflected from the weighted relaxation time spectra. © 2018 Wiley Periodicals, Inc.

“…The first mechanism involves diffusion through the Brownian motion of nanoparticles, which is strongly dependent on size and viscosity. Table 1 shows the rotary diffusion coefficients of particles with different shapes (L/D aspect ratio), where K B , T , and η s are the Boltzmann constant, temperature, and viscosity, respectively. Thus, the required time ( t D ) for a nanoparticle to travel a distance equal to its diameter can be calculated using the equation (Equation ) below

t_{D} = \frac{d^{2}}{4 D_{ro}}

This article critically reviews the detailed fundamental understanding of the influence of conductive nanoparticle migration on the localization, and hence, electrical conductivity of immiscible polymer blend nanocomposites. Three types of conductive nanoparticles, namely, spherical, tubular, and platelet, are discussed with respect to their migration and electrical conductivity of obtained nanocomposites. A complete migration process consists of bulk migration within one component, contact with the interface, and penetration to the other component. During processing, the wetting coefficient parameter is the main thermodynamically controlling factor for nanoparticle localization. However, kinetic effects, such as mixing sequence and intensity, viscosity ratio, size and shape of the nanoparticles, and mixing time, can play a substantial role in determining the final locations of nanoparticles. Moreover, the rate of migration varies with the surface chemistry of the nanoparticles. It has been reported that nanoparticles in a more viscous phase move slower compared with a low viscous phase. Furthermore, nanoparticles having high aspect ratios and surface polarities compatible with the other component migrating faster. It is established that immiscible polymer blend nanocomposites with a “double percolation” structure having higher conductivity with nanoparticles are localized at the interface of the co‐continuous blends.

“…The ability to absorb mechanical energy during cyclic loading of composites with such a filler increases when applying nanometer-sized copper particles [25]. The effect of fillers on the rheological properties of polymeric composites is considered in detail in article [26]. Using aluminum powder as an example, it is shown that the presence of a metallic filler in polysopren increases the polymer crystallinity, elevates the temperature of glass transition, and improves mechanical properties [27].…”
