“…It shows that there were the same FTIR bands for the CA‐1.1% to CA‐4.4% composites; this indicated that the CA synthesized at different proportions had stable composites. The spectrum of the CA was mainly characterized by the following bands: the band at 1664 cm −1 (pyridine ring vibrations, CN stretching) indicated the existence of the diazafluorene derivative; the bands at 1733 cm −1 (esters, aliphatic CO stretching), 3336 cm −1 (amido, vibrations NH stretching and terminal hydroxyl), and 1068 cm −1 (ether, antisymmetric stretching) supported the formation of urethane linkages; the bands at 2270 cm −1 (vibrations, NCO stretching), 1522 cm −1 (benzene ring skeletal vibrations), 2880 and 2939 cm −1 (CH stretching vibrations of methyl and methylene, respectively), and 762 cm −1 (out‐of‐plane CH bending) demonstrated the CA composites. Figure shows a comparison of the FTIR spectra of the novel CAs and PU membranes of the diazafluorene‐derivative‐modified PU CAs and N75 CA.…”

In this study, we synthesized a novel polyurethane (PU) curing agent (CA) modified by the diazafluorene derivative, 9,9′‐di(4‐hydroxyphenyl)‐9‐1H‐4,5‐diazafluorene, at different hydroxyl ratios. The results of 1H‐NMR and Fourier transform infrared spectroscopy proved the structure of the fluorine derivative and the modification of CAs. Differential scanning calorimetry and dynamic mechanical analysis showed that the glass‐transition temperature of the PU increased with the addition of the diazafluorene derivative, and the PU cured in the novel CA had more stable and better damping properties under moderate‐temperature conditions (30–80 °C) than the PU cured in the N75 CA. Tan δ was maintained in a relatively lower range shift in the moderate‐temperature range. The average adhesion values of the PU coating cured in the novel CA increased. The scanning electron microscopy morphologies of the PU film and the average adhesion of the coatings showed that the PU cured in the novel CA had good mechanical properties. © 2018 Wiley Periodicals, Inc.

“…A fiber can be made from any type of materials, including metals, alloys, ceramics, polymers, and their composites by different methods, e.g., melt‐spinning, wet‐spinning, electrospinning, scrolling, drawing, templated deposition, etc. Sometimes, surface treatment methods are accompanied . Moreover, fibers can be grouped into a cluster with programmed arrangements by processes of but not limited to twisting, braiding and weaving into yarn, braid, and fabric, respectively.…”

“…On one hand, polymer fibers can be coated by other materials on their surface. The basic purpose for polymer‐based composite fibers (not conducting polymer fibers) is endowing them with conductivity, which can be realized by coating metals, graphene, CNTs and conducting polymers . For example, Ni‐coated cotton yarns (Figure c) were made by electroless deposition method .…”

Fiber is a symbol of human civilization, being ubiquitous but obscure in society over most of history. Fiber has been revived upon the advent of fiber‐based electronic devices in the past two decades. This is due to its desirable lightweight, flexible, and conformable characteristics, which enable it to play a fundamental role in the electronic and information era. Numerous fiber‐based electronic devices have sprung up in energy conversion, energy storage, sensing, actuation, etc. A possibility is thereby conceived that they can be integrated into smart systems compatible with the human body, consisting of biotic fiber‐based organs and tissues, which possess similar but more advanced functions. However, the design of mono‐/multifibers, the construction of fiber‐based devices, and the integration of these smart systems represent great challenges in fundamental understanding and practical implementation. A systematic review of the current state of the art with respect to the design and fabrication of electronic fiber materials, construction of fiber‐based devices, and integration of smart systems is presented. In addition, limitations of current fiber‐based devices and perspectives are explored toward potential and promising smart integration.

“…In the development of vapour/gas sensing materials, the focus today is on promoting the combination of properties, such as ultrahigh sensitivity, fast response and recovery, high specificity, and good reversibility [ 8 , 9 ]. Thus far, numerous sensing materials have been reported, for example, semiconducting metal oxide (SMO) [ 10 ], nano-carbons, e.g., carbon nanotubes and graphene [ 11 ], organic semiconductors [ 12 ], intrinsically conducting polymers (ICPs) [ 13 , 14 , 15 ], and conductive polymer composites (CPCs) [ 16 ].…”

Aerogels Based on Reduced Graphene Oxide/Cellulose Composites: Preparation and Vapour Sensing Abilities

This paper reports on the preparation of cellulose/reduced graphene oxide (rGO) aerogels for use as chemical vapour sensors. Cellulose/rGO composite aerogels were prepared by dissolving cellulose and dispersing graphene oxide (GO) in aqueous NaOH/urea solution, followed by an in-situ reduction of GO to reduced GO (rGO) and lyophilisation. The vapour sensing properties of cellulose/rGO composite aerogels were investigated by measuring the change in electrical resistance during cyclic exposure to vapours with varying solubility parameters, namely water, methanol, ethanol, acetone, toluene, tetrahydrofuran (THF), and chloroform. The increase in resistance of aerogels on exposure to vapours is in the range of 7 to 40% with methanol giving the highest response. The sensing signal increases almost linearly with the vapour concentration, as tested for methanol. The resistance changes are caused by the destruction of the conductive filler network due to a combination of swelling of the cellulose matrix and adsorption of vapour molecules on the filler surfaces. This combined mechanism leads to an increased sensing response with increasing conductive filler content. Overall, fast reaction, good reproducibility, high sensitivity, and good differentiation ability between different vapours characterize the detection behaviour of the aerogels.
