Double walled carbon nanotubes (DWCNTs) are considered an ideal model for studying the coupling interactions between different concentric shells in multi-walled CNTs. Due to their intrinsic coaxial structures they are mechanically, thermally, and structurally more stable than single walled CNTs. Geometrically, owing to the buffer-like function of the outer tubes in DWCNTs, the inner tubes exhibit exciting transport and optical properties that lend them promise in the fabrication of field-effect transistors, stable field emitters, and lithium ion batteries. In addition, by utilizing the outer tube chemistry, DWCNTs can be useful for anchoring semiconducting quantum dots and also as effective multifunctional fillers in producing tough, conductive transparent polymer films. The inner tubes meanwhile preserve their excitonic transitions. This article reviews the synthesis of DWCNTs, their electronic structure, transport, and mechanical properties, and their potential uses.

Self-supporting carbon nanotube (CNT) Bucky-Papers have unique structural and surface properties which can be utilised in many applications. In this work we characterised pure selfsupporting CNT membranes, where CNTs were held together only by Van der Waals forces, and evaluated their potential and performance in direct contact membrane distillation. The membranes were found to be highly hydrophobic (contact angle of 113°), highly porous (90%), and to exhibit a thermal conductivity of 2.7 kW/m 2 •h. We demonstrate, as a proof of concept, that self-supporting CNT Bucky-Paper membranes can be used for desalination in a direct contact membrane distillation setup with 99% salt rejection and a flux rate of ~12 kg/m 2 *h at a water vapour partial pressure difference of 22.7kPa. Ageing of the membranes by delamination, factor limiting their performance, is also reported but work is currently done to address this issue by investigating composite material structures.

“…From our analysis, the shape of the pores is not typical and a wide range of size distribution exists. As previously noted, some parameters such as dispersion quality and specially CNTs properties including length, diameter, functionalization method and pressure condition can affect BP pores characteristics (Li and Kröger, 2012;Muramatsu et al, 2005;Smajda et al, 2007;Zhang et al, 2014). Normally, CNTs with smaller length and lower content develop small pore sizes (Li and Kröger, 2012) which is an important variable for pollutants rejection via membrane size exclusion.…”

“…The BP characteristics depend on some variables such as CNTs types (single walled or multi walled), synthesis procedure, CNT loading in the dispersion, applied vacuum or pressure and solvent type (Li and Kröger, 2012;Muramatsu et al, 2005;Smajda et al, 2007;Zhang et al, 2014).…”

acid removal from water using a novel fabricated antifouling carbon nanotube bucky -paper membrane and effect of operating parameters, Global NEST Journal, 19(2), 217-224.Humic acid removal from water using a novel fabricated antifouling carbon nanotube bucky -paper membrane and effect of operating parameters AbstractIn present work, a novel supported bucky paper (BP) membrane was fabricated and evaluated for humic acid (HA) removal from water. For better understanding the effect of operating variables, response surface methodology (RSM) was also applied. Three independent parameters namely TOC concentration (5, 10 and 15 mg l -1 ), operating time (10, 20 and 30 min) and transmembrane pressure (TMP) (1, 2 and 3 bar) were selected for TOC removal (%) and permeate flux analysis.The results revealed that the membrane could effectively remove HA primarily through electrostatic repulsion and then adsorption mechanisms. The study also showed that about 65% and 35% of the removed HA were through repulsion and adsorption mechanisms respectively. Based on analysis of variance (ANOVA), it was showed that the effect of TMP was strongly significant on the removal and flux (P-value <0.05). In addition, statistical test confirmed that RSM based on the Box-Behnken was a suitable method for optimizing the main operating variables for HA rejection using BP membrane (R In general, the synthesized BP membrane showed a relatively good rejection of HA and revealed antifouling properties over the filtration time.
