QCM nanocomposite gas sensors – Expanding the application of waterborne polymer composites based on graphene nanoribbon

Structure–Function Relationships of Nanocarbon/Polymer Composites for Chemiresistive Sensing: A Review

“…Despite the outstanding potential of a GNRs/polymer nanocomposite, there has been very limited research on the development of a GNRs/polymer nanocomposite in sensor applications. Trajcheva et al [ 30 ] fabricated the nanocomposite of GNRs/poly (methyl methacrylate-butyl acrylate (Hydroxyethyl)methacrylate) (p(MMA-BA-HEMA)) in different GNRs loading ranges (0.2–3.0 wt.%) by in situ mini-emulsion polymerization and used them as sensors for the detection of CO, NH 3 , and N 2 O gases. The prepared nanocomposite with 3.0 wt.% of GNRs demonstrated excellent mechanical properties with up to 66-fold, nine-fold, and a 2 orders of magnitude increase in Young’s modulus, offset yield stress, and storage modulus, respectively.…”

“…Table 3 presents a summary of the electrical conductivity and mechanical properties of GNRs/polymer composites. The presence of oxygen functional groups of GNRs facilitate rapid electron transfer that make the related nanocomposite suitable for sensing applications [30,35]. Despite the outstanding potential of a GNRs/polymer nanocomposite, there has been very limited research on the development of a GNRs/polymer nanocomposite in sensor applications.…”

“…In comparison with G as a zero-gap material, GNRs exhibit substantial energy band gaps, which is useful for tuning the electronic properties. The width, edge structure, and functionalization of GNRs make it a promising candidate for electronic devices and biomedical applications [ 18 , 27 , 28 , 29 , 30 , 31 , 32 ]. The tunable physical and electronic properties of GNRs hold promising potential for the fabrication of gas sensors [ 33 ] due to the high conductivity, resistance to electro-migration due to the strong inherent carbon–carbon bonds, extraordinary mechanical strength, and large current conduction capacity [ 26 , 33 , 34 ].…”

Highly Selective Chloromethanes Detection Based on Quartz Crystal Microbalance Gas Sensors with Ba-MOFs

“…The excellent sensing performance of QCM sensor is highly dependent on a stable material. If this material has open coordination sites, it will be beneficial to weak interaction with the analyte to speed up the response and increase the selectivity …”

Core‐shell structured magnetite silica‐supported hexatungstate: A novel and powerful nanocatalyst for the synthesis of biologically active pyrazole derivatives

“…[15,16,[20][21][22][23] On the other hand, in recent years, nanocomposites have attracted a lot of attention due to their wide applications in various fields such as photocatalysts [24,25] and catalysts, [26][27][28][29][30][31][32][33] lithium batteries, [34] biomedical, [35] solar cells, [36] and sensors. [37] Magnetic core-shell structured nanomaterials, as a special class of nanocomposites, are particularly important between researchers. Among these, the Fe 2 O 3 @SiO 2 NPs with Fe 3 O 4 core and silica O 19 ] nanocatalyst shell has attracted more attention.…”
