“…The reported resistance changes due to exposure to even smaller CO 2 concentrations are irreversible and their recovery has to be triggered by an additional UV irradiation step. Additionally, unlike PIL/CNTs‐ and polyethylenimine‐based sensors, the P[VBTMA][PF 6 ]/La 2 O 2 CO 3 sensors show instead of an increase a decrease of resistance upon exposure to CO 2 , which indicates a fundamentally different reaction mechanism. To assess the origin of this discrepancy we investigate the influence of CO 2 on the impedance spectra of the composite as shown in Figure c.…”

1wileyonlinelibrary.com oxidizing or reducing gases while operating at room temperature (RT). [16][17][18] Since then, electron conductive polymer-based sensors have attracted rapidly growing interest. [ 19 ] Particularly, the polymers with amino groups have been reported as promising candidates for CO 2 sensing, but in practice they suffer from poisoning with carbamates and therefore failed to fi ll the gap in the CO 2 gas sensor sector. [ 20,21 ] As a consequence, sensing of inert CO 2 gas is still performed with infrared spectroscopy, owing to trade-offs between the technological and economical factors, and having limited portability. Recently, poly(ionic liquid)s (PILs), a unique type of functional polyelectrolytes composed of ionic liquid repeating units chosen from structural diversity of the cation/anion-repertoire of ionic liquid chemistry, have been synthesized. [22][23][24] Their physical properties can be easily and broadly adjusted by the choice of the anion-cation pair. For example, structurally well-designed PILs are capable of reversible CO 2 capture and are showing high interfacial activity to bind various surfaces of metals, carbons, and to ionically interact with charged species via electrostatic repulsion or complexation. [25][26][27][28] Others demonstrated the ability of resistive CO 2 sensing with carbon nanotubes (CNTs) wrapped with poly[1-(p-vinylbenzyl)-3-methyl-imidazolium tetrafl uoroborate], P[VBTMA] [BF 4 ]. [ 29 ] They show a high sensitivity to low concentrations of CO 2 in oxygen-free atmospheres, but the response saturates already at 50 ppm, which is much lower than the normal CO 2 concentration level in fresh air (250 ppm) and thus lacks of practical application. Therefore, transforming the CO 2 sorption capacity of PILs into a chemoresistive sensor operating in real conditions, i.e., 21 vol% of oxygen and 50% relative humidity (rh), in the presence of 400 ppm [ 30 ] of CO 2 at RT requires a new structural model and additionally an understanding of the intrinsic interaction between organic and inorganic building blocks and their impact on the overall properties of such composites. Among different candidates, poly [( p -vinylbenzyl nanoparticles-both of which are intrinsically insulating materials-are utilized as building blocks, taking full advantage of the electrostatic interaction at their interface to boost the overall conductivity of composites at room temperature. To rationalize this unique behavior, the charge transport mechanism is studied using impedance spectroscopy. It is found fi nd that, for the composites with La 2 O 2 CO 3 content of 60-80 wt%, the interfacial effect becomes dominant and leads to the formation of conduction channels with increased mobility of [PF 6 ] − anions. These composites show further increase of the conductivity when exposed to pulses of CO 2 between 150 and 2400 ppm at room temperature in a relative humidity of 50%. This work therefore provides a simple strategy to achieve an enhancement of the electrical properties required for the utilizat...

“…We found that the fiber sensors show much lower sensitivity (Δ R / R o < 0.5%, near the noise level) to either carbon dioxide or oxygen flows (Figure S6, Supporting Information). With respect to change in resistance response of the graphene sensor with time of exposure of CO 2 and possible interference effects by protonation of the CO 2 by water vapor, an increased the amount of protonation would result in a decreased resistance rather than the observed increased one in our case . Similarly, because our glass fiber sensor is placed at a distance of 200 mm from one's noses during the exhalation process, a marginal increased temperature would only result in a decreased resistance ( Figure and Figure S7, Supporting Information), rather than the observed increase one in our case.…”

excellent electrically conductive materials; [3][4][5] 2) much attention has been paid to the production of electrically conductive GNPs in most frequently reported works from both academia and industry, based on chemical graphitization from graphene oxide (GO) to graphene and then reduction to hydrophobic reduced GOs (r-GOs). The multistep process, however, unavoidably causes structural damage and usually reducing agent gives rise to high sheet resistance; and 3) the deposition substrates are required to survive extremely harsh conditions (high temperature and oxygenation) during the multistep process, imposing limitations to future applications. Based on our approach, we fi nd out that the overlapping nanoparticle "skin" exhibits a high electrical conductivity, providing the fi rst example of a single fi ber sensor with diameter in micrometer-scale for sensing water vapor. Monitoring water vapor using a single glass fi ber and trace amounts of water vapor's liquid-solid phase change on a solid fi ber surface at nanoscale has not been reported yet. Water vapor is chosen for our study due to that it is not only a relatively common atmospheric constituent but also water interaction with hydrophobic carbon nanoparticles attracts a great interest for potential application in gas sensing, semiconductor manufacture, air fi lter, corrosion, catalysis, and electrochemistry. [6][7][8][9][10] Water vapor measurement or control is important for addressing structure safety, reliability, and durability from civil to aerospace engineering fi elds, because fundamental properties of concretes, plastics, and composites can vary largely with the adsorption of water vapor. In addition, we have sought to determine whether our nanoparticle-based "skin" can prevent supercooled trace water from icing when the water molecules contact the solid surfaces. We also interestingly report here that the "skin" enables highly sensitivity to in situ monitor the human breathing frequency.To investigate whether the carbon nanoparticles in oriented capillary fl ow can suppress "coffee ring" effect, we fi rst sought to deposit the GNPs onto a glass fi ber surface to form an overlapping nanoparticle "skin." Movie S1 (Supporting Information) shows an observation of oriented motion of GNPs solution that repels the coffee-ring effect at the water-glass fi ber interface as the water evaporated. We observed that the GNPs are carried to the air-water interface by the fi ber oriented capillary fl ow and in turn the formation of packed or arrested structures on the air-water interface. The orientation takes place when the capillary force prevails over the outward coffee-ring fl ow by the geometric constraints, [ 11 ] which prevents the suspended GNPs from reaching the drop edge and ensure uniform deposition.Consequently, the fi eld emission scanning electron microscopy (FESEM) images in Figure 1 and Figure S1 (Supporting Information) show morphological changes on fi ber surfaces in the absence and presence of graphene nanoplatelet deposition layers. We obser...

“…Accordingly, concentrations ranging from 0 to 0.2 % yield a linear response. However, at higher concentration values, the proportion of adsorption capacity is progressively reduced until it reaches its saturation point [49,50]. In the case of the rGO with linear PEI, a higher adsorption capacity of 8.10 mmol/g of CO2 at 273 K and low pressure has been reported [30,40].…”

The comparison between potential coatings for the measurement of CO2 concentration through the frequency shift in micro-resonators is presented. The polymers evaluated are linear polyethylenimine, branched polyethylenimine and reduced graphene oxide (rGO) by microwave reduction with polyethylenimine. The characterization of the coatings was made by using 6 MHz gold-plated quartz crystals, and a proof-of-concept sensor is shown with a diaphragm electrostatic microelectromechanical systems (MEMS) resonator. The methods of producing the solutions of the polymers deposited onto the quartz crystals are presented. A CO2 concentration range from 0.05% to 1% was dissolved in air and humidity level were controlled and evaluated. Linear polyethylenimine showed superior performance with a reaction time obtained for stabilization after the concentration increase of 345 s, while the time for recovery was of 126 s, with a maximum frequency deviation of 33.6 Hz for an in-air CO2 concentration of 0.1%.
