“…Another study carried out by Sattari et al (2014) [281] discovered that methane gas was efficiently sensed by CNT/polyaniline composites at room temperature. Likewise, Rajabi et al (2013) [282] applied CNT/polyvinyl chloride (PVC) mixed matrix membranes for gas separation applications. Khan et al (2014) [283] also established that similar nanocomposites that can function as indicator electrodes for titration of the potentiometric materials.…”

Fabrication, Functionalization, and Application of Carbon Nanotube-Reinforced Polymer Composite: An Overview

A novel class of carbon nanotube (CNT)-based nanomaterials has been surging since 1991 due to their noticeable mechanical and electrical properties, as well as their good electron transport properties. This is evidence that the development of CNT-reinforced polymer composites could contribute in expanding many areas of use, from energy-related devices to structural components. As a promising material with a wide range of applications, their poor solubility in aqueous and organic solvents has hindered the utilizations of CNTs. The current state of research in CNTs—both single-wall carbon nanotubes (SWCNT) and multiwalled carbon nanotube (MWCNT)-reinforced polymer composites—was reviewed in the context of the presently employed covalent and non-covalent functionalization. As such, this overview intends to provide a critical assessment of a surging class of composite materials and unveil the successful development associated with CNT-incorporated polymer composites. The mechanisms related to the mechanical, thermal, and electrical performance of CNT-reinforced polymer composites is also discussed. It is vital to understand how the addition of CNTs in a polymer composite alters the microstructure at the micro- and nano-scale, as well as how these modifications influence overall structural behavior, not only in its as fabricated form but also its functionalization techniques. The technological superiority gained with CNT addition to polymer composites may be advantageous, but scientific values are here to be critically explored for reliable, sustainable, and structural reliability in different industrial needs.

“…Khan et al incorporated pristine MWNTs into PIM-1, which caused as well an increase in gas permeabilities [12]. Rajabi et al reported on the addition of functionalised MWNT to polyvinylchloride (PVC) membranes which resulted in better gas separation performance, especially for CO 2 /CH 4 [22]. Studies by Kim and his group demonstrated that the permeabilities of O 2 , N 2 , and CH 4 increased proportionally to the amount of open-ended CNTs in the polymer matrix [23].…”

Gas Transport Properties of Polybenzimidazole and Poly(Phenylene Oxide) Mixed Matrix Membranes Incorporated with PDA-Functionalised Titanate Nanotubes

et al. 2017

Functionalised titanate nanotubes (TiNTs) were incorporated to poly(5,5-bisbenzimidazole-2,2-diyl-1,3-phenylene) (PBI) or poly(2,6-dimethyl-1,4-phenylene oxide) (PPO) for improving the interfacial compatibility between the polymer matrix and inorganic material and for altering the gas separation performance of the neat polymer membranes. Functionalisation consisted in oxidative polymerisation of dopamine-hydrochloride on the surface of non-functionalised TiNTs. Transmission electron microscopy (TEM) confirmed that a thin polydopamine (PDA) layer was created on the surface of TiNTs. 1.5, 3, 6, and 9 wt.% of PDA-functionalised TiNTs (PDA-TiNTs) were dispersed to each type of polymer matrix to create so-called mixed matrix membranes (MMMs). Infrared spectroscopy confirmed that –OH and –NH groups exist on the surface of PDA-TiNTs and that the nanotubes interact via H-bonding with PBI but not with PPO. The distribution of PDA-TiNTs in the MMMs was to some extent uniform as scanning electron microscope (SEM) studies showed. Beyond, PDA-TiNTs exhibit positive effect on gas transport properties, resulting in increased selectivities of MMMs. The addition of nanotubes caused a decrease in permeabilities but an increase in selectivities. It is shown that 9 wt.% of PDA-TiNTs in PBI gave a rise to CO2/N2 and CO2/CH4 selectivities of 112 and 63 %, respectively. In case of PPO-PDA-TiNT MMMs, CO2/N2 and CO2/CH4 selectivity increased about 25 and 17 %, respectively. Sorption measurement showed that the presence of PDA-TiNTs in PBI caused an increase in CO2 sorption, whereas the influence on other gases is less noticeable.

“…Figure shows a comparison of CO 2 /CH 4 separation performances of several promising sorption–diffusion polymeric membranes and the studied PVA/[m-2HEA][Pr] membranes. The materials selected for this comparison have been reported to target the attractive area close to or above the so-called “Robeson upper bound”, including polyimide, ,,− polysulfone, ,,− thermally rearranged polymers (TR) ,,− and polycarbonates, and miscellaneous polymers. ,,− As can be observed, TR and polyimides showed the highest permeabilities and were also associated with moderate-to-high CO 2 /CH 4 selectivity. It is worth mentioning that TR membranes are usually synthesized from polyimides and polyamides with hydroxyl or thiol groups and undergo thermal treatment to reduce their polymer packing efficiency .…”

Alkanolamine + carboxylic acid-based ionic liquids have shown promising high CO 2 selectivities. Their addition to cellulose acetate (CA) and polyvinyl alcohol (PVA) was investigated in the present study. The N-methyl-2-hydroxyethylammonium propionate IL [m-2HEA][Pr] significantly enhances the CO 2 separation performance of PVA. Scanning electron microscopy, Fourier transform infrared spectroscopy, and nuclear magnetic resonance analyses indicate that the IL−PVA combination produced IL composite membranes with interactions being predominantly physical. Furthermore, the IL addition to CA produced porous membranes with apparent low CO 2 separation efficiency. Pure gas permeation experiments indicate that increasing IL concentration of PVA-based membranes promotes higher gas permeabilities. The membranes were prepared containing up to 60.3 wt % of [m-2HEA][Pr], which resisted pressure differentials up to 6 barg. PVA containing 45.5 wt % of IL produced the most promising results, achieving 26 barrer of CO 2 permeability and permselectivities of 122 and 213 for CO 2 /CH 4 and CO 2 /N 2 , respectively. This result was compared to promising materials from the literature and indicated the overall high CO 2 /CH 4 and CO 2 / N 2 selectivities of PVA/[m-2HEA][Pr] membranes, which overcome even the 2008 Robeson's upper boundary.
