A room temperature operating electronic nose (e-nose) has been developed by the assembly of conductive polymer nanocomposite (CPC) quantum resistive sensors (QRS). The fabrication QRS spray layer (sLbL) CPC solutions allowed us to obtain transducers with reproducible initial properties that could be easily tailored adjusting either number sprayed layers and/or solution composition. selectivity was varied changing chemical nature matrix in which carbon nanotubes (CNTs) were dispersed...
Sensing skins made of reduced graphene oxide (RGO) based quantum resistive vapour sensors (vQRS) have been developed by combining two original processes, i.e., the synthesis phase transferable sheets using ionic liquid polymers (PIL) and structuring 3D conducting architectures spray layer (sLbL) technique. Many advantages can be derived from this new technology, such as versatility fabrication (sprayability, no need for a clean room), flexibility, potential transparency low cost, making vQRS...
Here, we report a new method to prepare graphene from graphite by the liquid phase exfoliation process with sonication using oxide (GO) as dispersant. It was found that GO nanosheets act surfactant mediated of into GO-adsorbed complex in aqueous solution, which separated an additional process. The preparation isolated single few layers is routinely achieved yield up higher than 40% initial material. prepared sheets showed high quality (C/O ∼ 21.5), low defect (ID/IG 0.12), and conductivity...
Sensing skins about 1.5 μm thick made of 40 nanolayers conductive polymer nanocomposites (CPC) were sprayed layer by (sLbL) directly on a PET woven textile to demonstrate their versatility monitor the deformation flexible, rigid and rough substrate such as commercial boat sail. CPC sensing developed structuring 3D carbon nanotubes network into three kinds amorphous thermoplastic matrices (PMMA, aPS, PC). Adjustable parameters thickness (number layers) initial resistance transducers (CNT...
Reinforced polymer–matrix composites are widely used under sliding contact conditions in various boating and automotive applications. In this paper, the friction wear of bulk epoxy carbon filler reinforced have been investigated using a pin-on-disc tribometer. The effect different fillers on tribological behavior an has studied treated untreated nanotubes, graphite, mixture graphite nanotubes. Filler addition greatly enhances properties resin, by reducing coefficient rate. addition, it was...
Conductive nanostructured composites combining an epoxy and graphene have been explored for application as high-performance piezo-resistive mechanical sensor.
Abstract Hybrid materials of Fe 3 O 4 ‐decorated reduced graphene oxide (Fe ‐RGO) and poly(3,4‐ethylenedioxythiophene) (PEDOT) were prepared by poly(ionic liquid)‐mediated hybridization. In this hybrid material, liquid) was found to perform multiple roles for: (1) stabilizing ‐RGO against aggregation in the reaction medium, (2) transferring nanomaterials from aqueous into organic phase, (3) associating with PEDOT. The PEDOT showed lowest surface resistivity 80 Ω sq −1 at an RGO‐Fe loading 1...
For the first time vapour sensors were made by assembling multi-wall carbon nanotube (CNT) decorated poly(methyl methacrylate) microbeads (PMMAµB) spray layer (sLbL). This combination of materials and technique resulted in an original hierarchical architecture with a segregated network CNT bridging PMMAµB. The chemo-resistive behaviour these conductive polymer nanocomposite (CPC) was studied terms sensitivity selectivity towards standard volatile organic compounds (VOC), as well...
A hybrid composite material of graphene and carbon nanotube (CNT) for high performance chemical temperature sensors is reported. Integration 1D 2D materials into composites achieved by coupling CNT through poly(ionic liquid) (PIL) mediated‐hybridization. The resulting CNT/PIL/graphene are explored as active in sensors. For sensing application, the integrated a chemo‐resistive sensor to detect general class volatile organic compounds. Compared with graphene‐only devices, film device showed an...
