“…It should be noted that the MWCNT-coated cellulose fibers exhibit a positive vapor coefficient for ethanol and acetone vapors, which is also found in other CNT-based sensory materials for vapor sensing [17,[27][28][29][30]. As reported previously, the change of resistance of CNT-based materials as sensors for vapors is mainly due to two reasons.…”

“…One reason is the adsorption of electron-donating VOC molecules, compensating for the hole carriers in semiconductive MWCNTs and causing the increase of electrical resistance [27]. Another probable reason is that the adsorption of VOC molecules also directly causes the swelling of the polymer, resulting in the change in the microstructure of MWCNT networks in the matrix or on the surface [17,28,29]. As a result, in our cases, it can be deduced that the resistance responses of MWCNT-coated cellulose fibers for VOC can be attributed to the adsorption of VOC molecules by both the cellulose fiber and the CNT networks.…”

Smart multi-walled carbon nanotube (MWCNT)-coated cellulose fibers with a unique sensing ability were manufactured by a simple dip coating process. The formation of electrically-conducting MWCNT networks on cellulose mono-and multi-filament fiber surfaces was confirmed by electrical resistance measurements and visualized by scanning electron microscopy. The interaction between MWCNT networks and cellulose fiber was investigated by Raman spectroscopy. The piezoresistivity of these fibers for strain sensing was investigated. The MWCNT-coated cellulose fibers exhibited a unique linear strain-dependent electrical resistance change up to 18% strain, with good reversibility and repeatability. In addition, the sensing behavior of these fibers to volatile molecules (including vapors of methanol, ethanol, acetone, chloroform and tetrahydrofuran) was investigated. The results revealed a rapid response, high sensitivity and good reproducibility for these chemical vapors. Besides, they showed good selectivity to different vapors. It is suggested that the intrinsic physical and chemical features of cellulose fiber, well-formed MWCNT networks and favorable MWCNT-cellulose interaction caused the unique and excellent sensing ability of the MWCNT-coated cellulose fibers, which have the potential to be used as smart materials.

“…Recently, to extend the uses of natural cellulose in advanced application areas including transistor [5], sensor [6], actuator [7], supercapacitor [8], electric heater [9], and electromagnetic interference (EMI) shielding materials [10], one-dimensional carbon nanotubes (CNTs) and their derivatives with high aspect ratio have been chosen as nano-scale functional fillers for cellulosebased composite papers and films, because of their exceptional electrical conductivity, thermal conductivity, mechanical modulus, and thermal stability [11,12]. Generally, a papermaking technique for CNT/cellulose composite papers was known to be efficient and eco-friendly, compared to solution processes for cellulose-based composite films requiring toxic polar or expensive ionic liquid solvents to dissolve hydrogen-bonded cellulose crystals.…”

“…88 Cellulose based hybrid nanocomposites have also been employed for the detection of toxic and harmful gases in gas sensors, and chemical vapor sensors. 89 Highly sensitive gas sensors were developed based on SWNT networks prepared from aqueous hydroxypropyl cellulose-assisted dispersions. 90 The sensor can detect the level of 25 ppb or lower concentrations of NO 2 and 5 ppm ammonia, and showed almost no baseline drift after multiple NO 2 exposures at room temperature.…”

Cellulose, the chain of glucose residues easily obtained from nature, is the most common natural polymer. Owing to its own unique material properties, compared to the conventional usage, nanocellulose (NC) with a crystalline structure can be considered to be used in various industrial applications. As a novel sustainable future material, we review the recent achievements of NC from the view point of material extraction and the composite processes to some extended important applications. While the mechanical properties of NCs and the energy consumption during their composite processing are the key considerations, their application potentials have never been limited to mechanical or commodity products as conventional celluloses. In the latter part of this review, emerging engineering applications of NCs such as energy storage, flexible electronics, and smart materials will be further discussed for readers searching future high-end eco-friendly functional materials. Also some suggestions for potential applications will be also discussed.
