A novel continuous process for synthesis of carbon nanotubes using iron floating catalyst and MgO particles for CVD of methane in a fluidized bed reactor

Enhanced dielectric and mechanical properties in chlorine-doped continuous CNT sheet reinforced sandwich polyvinylidene fluoride film

“…By analyzing the intensity of G-band with respect to that of D-band (I G /I D ), the degree of order in carbon material can be determined qualitatively. It is previously reported that the floating catalyst CVD method allows production of CNT with high purity and order in structure [36,37]. In our case, the ratio I G /I D of P-CNT sheet reaches 10.71 which indicates very high degree of order and very few defects in CNTs [25].…”

Continuous production of carbon nanotubes – A review

“…According to So et al (2009), the use of this technique is to ensure the decomposition of hydrocarbon gas and the reaction between the decomposed gas and the catalyst proceeds separately. Lastly in the case of the fluidized-bed reactor, the process is started with the reaction chamber firstly heated to a reaction temperature according to [2], [26] and [23]. This is followed by the injection of a catalyst at a predetermined rate which is carried by the flow of methane and inert gases into the reaction zone [23,26] or it is carried just by the inert gas [2].…”

“…Only recently, the continuous synthesis of CNTs has been a hot topic of discussion due to their ability to grow large quantities of CNTs effortlessly. These techniques include but are not restricted to arc-jet plasma [5], simplified carbon-arc [16], floating catalyst [26] and fluidized-bed CVD [23]. The new techniques have been developed due to the difficulty of current methods to grow high quantities of CNTs.…”

Improving flexural and dielectric properties of MWCNT/epoxy nanocomposites by introducing advanced hybrid filler system

“…The CNT-inorganic filler synthesised by CVD will possess a strong bond between CNT and the inorganic filler, which prevents the detachment of CNT during the fabrication of the polymer composites. In the last few years, the hybridization of CNT with inorganic fillers such as Al 2 O 3 , MgO, SiO 2 , CaO and ZrO 2 were successfully performed using CVD [25,26]. Researchers focused on the hybridization of CNT with Al 2 O 3 due to the interesting properties of Al 2 O 3 such as high hardness, excellent dielectric properties, good thermal properties, as well as, refractoriness [27].…”
