Abstract We investigate the effect of water adsorption on electrical properties graphene oxide (GO) films using direct current (DC) measurement and alternating (AC) complex impedance spectroscopy. GO suspension synthesized by a modified Hummer's method is deposited Au interdigitated electrodes. The strong interaction molecules with was observed through characterizations. DC results show that are humidity- applied voltage amplitude-dependent. AC spectroscopy used to analyze mechanism between...
Based on good dispersion of multi-walled carbon nanotubes (MWCNTs) in graphene oxide (GO) solution, MWCNTs/GO composite film was fabricated a quartz crystal microbalance (QCM) by simple drop-casting method. The responds quickly to relative humidity changes. QCM with coating showed the highest sensitivity among QCMs coated different films (MWCNTs, GO, and MWCNTs/GO). By monitoring changes both resonant frequency impedance sensors, it is found that motional resistance quality factor (Q) have...
We have developed an electro-chemical deposition approach to synthesize various structures of Ag NPs on carbon fibers. This improved both the tensile strength and interfacial property as much 57.2% 27.2%, respectively.
This study focuses on a novel humidity sensor composed of graphene-oxide (GO)-supported MoTe2 nanosheets. Conductive Ag electrodes were formed PET substrates by inkjet printing. A thin film GO-MoTe2 was deposited the electrode used for adsorbing humidity. The experiment's results demonstrate that are attached to GO nanosheets uniformly and tightly. capacitive output sensors with various ratios GO/MoTe2 has been tested different levels (11.3-97.3%RH) at room temperature (25 °C). As...
Abstract Zeolitic imidazolate framework‐8 (ZIF‐8) was used to enhance the interfacial strength of composites due its large specific surface area, uniform pore size, and high stability. Morphology‐controllable ZIF‐8 nanocrystals were synthesized by solvent method a layer small‐sized height crystalline deposited on carbon fibers via an efficient electrophoretic deposition (EPD) way. The results showed that interlaminar shear (ILSS) tensile (TS) fibers/epoxy TS fiber enhanced 43.56% 25.48%,...
Silica aerogel (SA) was functionalized by γ-amino propyl triethoxy silane (APTES) with long chain amino groups, and this surface-functional SA filled into rigid polyurethane (PU) foams to enhanced mechanical property thermal insulation. It proved that the active functional groups different content of (0.3, 0.5, 0.7 0.9 wt%) played important roles in controlling cellular structure PU foams. The results scanning electron microscopy (SEM) water absorption showed surface-functionalized made cell...
Fullerenes (C60) exhibits many advantageous properties but its poor solubility seriously restricts applications. In this paper, C60 is dissolved in graphene oxide (GO) aqueous solution homogenously. This water-soluble composite material of GO/C60 used for making a capacitive humidity sensor. sensor shows sensitivity three times larger than that the based on film. The possible reason uniformly adsorbed surface GO, thus reducing agglomeration C60. supported by TEM, FTIR, and complex impedance test.
Humidity sensors based on graphene oxide quantum dots (QDs-GO) with rapid response were developed. Results proved that these QD-GO-based exhibit a subsecond response. The effect of film thickness time was discussed. possible theory intersection density proposed to explain the behavior QD-GO humidity sensors. This letter demonstrated may have various applications, such as human breath monitoring.
In this paper, hyperbranched polyether functionalized graphene oxide (EHBPE-GO) was prepared by a facile one-step method. Fourier transform infrared spectroscopy (FTIR), X-ray diffractometry (XRD), thermogravimetric analyzer (TGA), and trans-mission electron microscopy (TEM) results confirmed the formation of EHBPE-GO. Then, EHBPE-GO cured with phenolic amides at room temperature to prepare epoxy coatings. The corrosion resistance coatings investigated systematically using electrochemical...
A new approach to greatly reduce the cross‐sensitivity of a quartz crystal microbalance (QCM) humidity sensor is proposed. graphene oxide (GO) membrane, which acts as filter layer, added structure. Since GO membrane enables selective permeation water molecules, introduction into structure reduces other gases.
