“…The investigation confirmed that CNT-BPs can be used to fabricate high-loading CNT/thermoplastic composites with improved thermal properties [101]. Mixed single-walled and multi-walled carbon nanotube membrane (buckypaper) was incorporated onto the surface of polyimide/carbon fiber composites via compression moulding process [102][103][104]. Flammability was investigated by cone calorimeter tests under an external radiant heat flux of 50 kWm -2 .…”

“…The buckypaper worked as an excellent physical barrier, obstructing the flow of heat and oxygen to the inner polymer resin. The as-prepared buckypaper greatly improved the fire retardancy of polyimide matrix carbon fiber composites [104]. Carbon nanotube buckypaper/thermoplastic polyurethane elastomer composites were successfully fabricated [105].…”

This review is a comprehensive source for synthesis, functionalization, and physical properties of polymer/carbon nanotube (CNT) nanocomposites. Effectiveness of processing methods for CNT reinforcement in matrix for proper dispersion and appropriate interfacial adhesion is discussed. Novelty of polymer/CNT buckypaper fabrication with preformed networks through microfiltration of nanotube suspension has also been discussed. Moreover, preparation, properties and manufacturing proficiencies of buckypaper are reviewed. Different approaches of intertwining buckypaper through infiltration, compression, soaking, and dry transfer have been analyzed. Polymer/CNT buckypaper obtained by vacuum infiltration have micron-scale bicontinuous morphology and improved thermal properties due to effectual heat transfer within nanotube rich phase.

“…However, BP membranes' typical microcracks, hydrophobicity, and lack of mechanical handling ability may limit their application in certain processes, such as desalination . Consequently, the mechanical characteristics of BP membranes can be improved using adhesives or through polymer incorporation . BPs have been mechanically reinforced through soaking in polymer solutions, such as poly (vinyl pyrrolidone) (PVP), polystyrene, and poly (vinyl alcohols) (PVA) .…”

“…They have high porosity and a large free volume, with a pore diameter distribution ranging from 1 nm to well over 100 nm, making this material suitable for the incorporation of polymers . One such polymer is chitosan, which has the capacity to significantly enhance mechanical properties . Chitosan consists of a linear polysaccharide chain containing a 1, 4‐glycosidic linkage, a structure generated by partial deacetylation of chitin, a key component in crustacean shells (eg, crab, shrimp, and crawfish).…”

The preparation and characterization of buckypaper made from carbon nanotubes impregnated with chitosan

Biopolymer chitosan was incorporated into a thin multiwalled carbon nanotube membrane (MWNT buckypaper) via filtration and soaking in 0.1% (w/v) of low‐molecular‐weight (MW) chitosan. The properties of the buckypaper membrane before and after annealing and after soaking were characterized by measurement of their electrical conductivities (19 ± 2 to 42 ± 2 S/cm), contact angles (31 ± 4° to 71 ± 4°), and mechanical properties (tensile strength, small‐ranging between 1.4 ± 0.1 and 4.2 ± 0.7 MPa; Young's modulus: 85 ± 4 to 443 ± 20 MPa). Moreover, the morphological properties, surface area, and permeability toward water of these buckypaper membranes were characterized and compared with corresponding carbon nanotube membranes prepared with Triton X‐100 (Trix) as the surfactant. Scanning electron microscopic (SEM) images and Brunauer, Emmett, and Teller (BET) data of MWNT‐annealing buckypaper membranes revealed that the diameters of their surface pores were significantly higher than that of the corresponding buckypaper membranes soaked in chitosan solution. The solution of chitosan incorporated inside the porous structure of the annealed MWNT membrane led to a significantly reduced surface area and pore size distribution of the composite membrane, revealing that this could be a useful method for desalination.

Advantage of Fractional Calculus Based Hybrid‐Theoretical‐Computational‐Experimental Approach for Alternating Current Voltammetry

et al. 2020

The dynamic electrochemical behavior of electroactive species is believed to be represented better by the fractional calculus, because it can consider the history of mass-transfers of that species near the electrode surface. The elucidation of mathematical fundamentals of fractional calculus has been recently introduced for batteries, supercapacitors and a few voltammetry studies. The working equations for faradaic fundamental and second-harmonic (SHac) components of alternating current (ac) for ac voltammetry of an electrochemically reversible redox reaction on an electrode of macroscopic diameter have been derived here by using generalized formulae of the fractional calculus. A computation code is written in Python language with a matrix based algorithm developed based on latest, accurate, efficient and stable Grunwald-Letnikov-Improved fractional-order differentiation equation. That computational code is used to find the concealed faradaic fundamental, SHac components of the total current and other double-layer parameters of experimentally recorded voltammograms of ruthenium (III/II) redox reaction on gold-disc electrode by a common electrochemical workstation without having inbuilt Fourier transformation features. The amplitude of the computed faradaic current concealed in the experimental data gets enhanced through this hybrid theoretical-computational-experimental approach and thus it keeps scope of application and further improvement in electroanalysis.
