“…In the calculations, Poisson's ratio of 0.3 [32][33], density of 2.0 g/cm 3 [30,34,35], Young's modulus of 50 GPa [36][37][38], and estimated aspect ratio of 100 were used for MWCNTs, and Poisson's ratio of 0.35 [39,40] and Young's moduli measured for HDPEPEgMA reference samples (0.66-0.70 GPa) were used for the matrix.…”

“…For CVD-grown MWCNTs, Young's moduli are lower than 100 GPa [36,37] and values are strongly dependent on tube diameter [38]. For our calculations, therefore, we used a Young's modulus of 50 GPa for MWCNTs.…”

“…Carbon nanotubes (CNTs) [1] are based in a unique material that possesses high mechanical strength, ballistic conduction, high temperature thermal stability and high surface area [2][3][4][5]. All these extraordinary properties make them a useful material for various kinds of applications such as supercapacitors [6,7], sensors [8], field emitters [9] and for the removal of contaminants from water and gases [10,11].…”

“…CNTs have been shown to be an efficient adsorbent for the elimination of dibenzo-p-dioxin from contaminant water [12]. Also, they can adsorb a variety of gases and have been proven to be superior to activated carbon for the removal of dioxin1,2-dichlorobenzene from water in a wide range of pH (3)(4)(5)(6)(7)(8)(9)(10) [11,13]. Recently, X Ma et al, [14] have shown the adsorption/desorption of chlorinated compounds by pristine and thermally treated multi-walled carbon nanotubes.…”

Background: Air pollution has become an important issue worldwide due to its adverse health effects. Among the different air contaminants, volatile organic compounds (VOCs) are liquids or solids with a high vapor pressure at room temperature that are extremely dangerous for human health. Removal of these compounds can be achieved using nanomaterials with tailored properties such as carbon nanotubes. Methods: Vertically-aligned multiwall carbon nanotubes (CNTs) were successfully grown on quartz filters by means of plasma enhanced chemical vapor deposition (PECVD). Furthermore, a plasma treatment was performed in order to modify the surface properties of the CNTs. The adsorption/desorption processes of three chlorinated compounds (trichloroethylene, 1,2-dichlorobenzene and chloroform) on the CNTs were studied using mass spectrometry measurements with a residual gas analyzer. Results: The adsorption capability of the CNTs increased after functionalization of their surface with a water plasma treatment. In addition, it was found that the presence of aromatic rings, water solubility and polarity of the VOCs play an important role on the adsorption/desorption kinetics at the CNTs surface. Conclusions: This study demonstrates the applicability of CNTs deposited on quartz filters for the removal or selective detection of volatile organic compounds (VOCs). The presence of aromatic rings in VOCs results in π-stacking interactions with a significant increase of their adsorption. On the other hand, it was found that CNTs surface interactions increase with water solubility and polarity of the VOC.

“…CVD materials contain residual catalyst particles, and sometimes amorphous carbon, but are otherwise relatively pure. On the other hand, these gas-phase processes operate at lower temperatures and lead to structurally imperfect nanotubes, often with seriously reduced intrinsic properties 26 . It is worth noting that there are currently around four orders of magnitude between the most expensive and cheapest commercial nanotube products.…”

Due to the remarkable physical and mechanical properties of individual, perfect carbon nanotubes (CNTs), they are considered to be one of the most promising new reinforcements for structural composites. Their impressive electrical and thermal properties also suggest opportunities for multifunctional applications. In the context of inorganic matrix composites, researchers have particularly focussed on CNTs as toughening elements to overcome the intrinsic brittleness of the ceramic or glass material. Although there are now a number of studies published in the literature, these inorganic systems have received much less attention than CNT/polymer matrix composites. This paper reviews the current status of the research and development of CNT-loaded ceramic matrix composite materials. It includes a summary of the key issues related to the optimisation of CNT-based composites, with particular reference to brittle matrices and provides an overview of the processing techniques developed to 2 optimise dispersion quality, interfaces and density. The properties of the various composite systems are discussed, with an emphasis on toughness; a comprehensive comparative summary is provided, together with a discussion of the possible toughening mechanism that may operate. Lastly, a range of potential applications are discussed, concluding with a discussion of the scope for future developments in the field.3
