Flexible conductive nanocomposites with the ability of self‐assembly into well‐ordered structures are promising multifunctional materials for energy conversion and storage devices. In this work, flexible nanocomposites based on multi‐walled carbon nanotubes (MWCNTs) and poly(styrene‐butadiene‐styrene) (SBS) were obtained by solution casting, followed by a post‐annealing treatment, during 7 days at 110 °C, to enable the self‐organization of the SBS. The impact of the MWCNTs on the self‐assembly was studied by atomic force microscopy and Small angle X‐rays scattering, and the conductivity of these nanocomposites was analyzed over the broadband frequency range, that is, 10−1–106 Hz. The results revealed that the lower MWCNTs loadings (∼0.2 v %) were the most suitable to achieve a conductive network through the SBS, maintaining self‐assembled domains. These domains include hexagonally packed cylinders and alternating lamellae. Furthermore, at loadings above 1 v %, the impact of further MWCNTs addition on the conductivity was marginal over the whole frequency range and the self‐assembly tendency was progressively reduced. © 2018 Wiley Periodicals, Inc.

“…Some researchers have also focused on the ability of the outstanding mechanical properties of CNTS to improve durability and tribological characteristics. There have been several attempts to exploit CNTs in reinforcing polymers [17,18] or metal composites [19][20][21]. The utilization of CNTs as additives in lubricants has also been considered by several researchers [22,23].…”

Study on frictional behavior of carbon nanotube thin films with respect to surface condition

In this work, tribological characteristics of thin films composed of entangled carbon nanotubes (CNTs) were investigated. The surface roughness of CNT thin films fabricated via a dip-coating process was controlled by squeezing during the process with an applied normal force ranging from 0 to 5 kgf. Raman spectra and scanning electron microscopy (SEM) images of the thin films were obtained to estimate the influence of the squeezing process on the crystallinity of the CNTs. The analysis revealed that squeezing could reduce surface roughness, while preserving the crystallinity of the CNTs. Moreover, the surface energy of the cover glass used to press the CNT thin film was found to be the critical factor controlling surface roughness. A micro-tribometer and macro-tribometer were used to assess the tribological characteristics of the CNT thin film. The results of the tribotest exhibited a correlation between the friction coefficient and surface roughness. Dramatic changes in friction coefficient could be observed in the micro-tribotest, while changes in friction coefficient in the macro-tribotest were not significant.

The application of composite microspheres closely lies on their morphology and properties. In this work, carbon nanotubes (CNTs) reinforced composite microspheres were prepared via in situ polymerization: methyl methacrylate was selected as matrix to copolymerize with cationic comonomer 2-(methacryloyloxy)ethyltrimethyl ammonium chloride, using CNTs as nanofillers to fabricate composite microspheres. The morphology, molecular weight, and thermal properties of obtained composite microspheres with different monomer feeding ways (batch polymerization and dropwise monomer feeding procedure) and reaction time (1-6 h) were investigated. The results revealed that dropwise monomer feeding procedure leaded to remarkably decreased diameter of composite microspheres. Compared with polymer microspheres, the addition of CNTs resulted in earlier formation of composite microspheres. When the reaction time was controlled for 1-6 h, the morphology of the composite microspheres underwent a shape change from deformed particles to spherical structure. Although reaction time had no significant effect on molecular weight, the thermal property was gradually improved with increase of reaction time. For ensuring the effectiveness of the produced composite microspheres and tailoring them for any specific application, our investigation shows significant reference value on choosing feeding ways and controlling reaction time to obtain different morphology microspheres.
