“…The values of the elongation obtained by us vary between 120% and 180%. Various values ranging from 22% to 280% elongation are reported in the literature and our values are higher than most of the reported values 10,13,16,36,41 . Higher elongation values in our nanocomposites might be due to the sliding of GnP in the PVA matrix.…”

“…In addition to this, our values of DC conductivity values are higher than other PVA composites like rGO–PVA nanocomposites, 47 LrGO–PVA nanocomposites, 28 SrGO–PVA nanocomposites, 28 multi‐walled carbon nanotube (MWCNT)–PVA nanocomposites, 10 GO–PVA–PEDOT–PSS nanocomposites, 48 and GP–PVA nanocomposites 7 . However, it is also worth to be mentioned that a few coworkers have reported higher values of conductivity up to 25 S/m with various fillers like rGO–PVA nanocomposites 27,49 and SRGO/HRGO–PVA nanocomposites 50 .…”

The improvement in elongation observed could also be due to the plasticizing effect of PVA in the presence of GnP.…”

“…Recently, there has been an increasing drive towards the development of conductive polymer matrix, which could be used in a wide range of relevant technological applications, such as sensor, 1 antistatic, 2 microwave absorbing, 3 and conductive coating 4,5 . Among the various composites, carbon‐based fillers such as carbon black, 6 graphite, 7,8 graphene oxide (GO), 9 carbon nanotube (CNT), 10–12 and graphene 13 are particularly studied due to its high electrical conductivity, thermal stability, mechanical strength, and ease of processing. Uniform dispersion of nano‐sized fillers in polymer matrix brings large interfacial area per unit volume.…”

Polymer based nanocomposites are gaining attention in various fields of science and technology due to its tunable properties. In this work, we report for the first time, the preparation and study on electrical and mechanical properties of standalone poly(vinyl alcohol) (PVA) based graphite nanoplatelet (GnP) composite films using modified film casting technique. Our modified tape casting method can produce films with uniform thickness, and uniform dispersion of filler deprived of pinholes. This technique is scalable for the mass production of polymer composite films for device application. We have obtained a significant enhancement in the electrical conductivity of 9 orders of magnitude and a maximum value of 0.143 S/m using PVA-GnP composites. To the best of our knowledge, this increase is the highest among the reported values for PVA-GnP composite films. However, a reduction in crystallinity and tensile strength can be seen with the addition of GnP fillers. The maximum tensile strength obtained for PVA-GnP composite films was 15 MPa and is adequate for use in electronic applications and devices. The effect of filler addition in PVA is discussed in detail.

“…A first step towards the synthesis of monoliths for technical applications was taken by Shen et al, who focussed on a more economical synthesis protocol using low-cost MWCNTs [11]. While the use of MWCNTs could reduce material costs, the applied protocols in literature still require prolonged time for gelation and special drying techniques such as supercritical fluid drying [11,12,15,17,20]. Thus, the synthesis becomes complex and time-intensive, further reducing the cost-performance ratio of the resulting monoliths [21].…”

Design of 3D Carbon Nanotube Monoliths for Potential-Controlled Adsorption

The design of 3D monoliths provides a promising opportunity to scale the unique properties of singular carbon nanotubes to a macroscopic level. However, the synthesis of carbon nanotube monoliths is often characterized by complex procedures and additives impairing the later macroscopic properties. Here, we present a simple and efficient synthesis protocol leading to the formation of free-standing, stable, and highly conductive 3D carbon nanotube monoliths for later application in potential-controlled adsorption in aqueous systems. We synthesized monoliths displaying high tensile strength, excellent conductivity (up to 140 S m−1), and a large specific surface area (up to 177 m2 g−1). The resulting monoliths were studied as novel electrode materials for the reversible electrosorption of maleic acid. The process principle was investigated using chronoamperometry and cyclic voltammetry in a two-electrode setup. A stable electrochemical behavior was observed, and the synthesized monoliths displayed capacitive and faradaic current responses. At moderate applied overpotentials (± 500 mV vs. open circuit potential), the monolithic electrodes showed a high loading capacity (~20 µmol g−1) and reversible potential-triggered release of the analyte. Our results demonstrate that carbon nanotube monoliths can be used as novel electrode material to control the adsorption of small organic molecules onto charged surfaces.
