Real time polymer nanocomposites-based physical nanosensors: theory and modeling

Abstract

Functionalized carbon nanotubes and graphene nanoribbons nanostructures, serving as the basis for the creation of physical pressure and temperature nanosensors, are considered as tools for ecological monitoring and medical applications. Fragments of nanocarbon inclusions with different morphologies, presenting a disordered system, are regarded as models for nanocomposite materials based on carbon nanoсluster suspension in dielectric polymer environments (e.g., epoxy resins). We have formulated the approach of conductivity calculations for carbon-based polymer nanocomposites using the effective media cluster approach, disordered systems theory and conductivity mechanisms analysis, and obtained the calibration dependences. Providing a proper description of electric responses in nanosensoring systems, we demonstrate the implementation of advanced simulation models suitable for real time control nanosystems. We also consider the prospects and prototypes of the proposed physical nanosensor models providing the comparisons with experimental calibration dependences.

“…The development of functional nanomaterials with high sensitivity and reproducibility is highly desirable for practical applications but very challenging. − Nanostructured materials are very interesting because of their unique properties at the nanoscale level that significantly enhance the physical and chemical properties that are desirable for potential applications. − In addition, the reliable and controllable doping of nanomaterials or the embedding of a combination of other functional materials into a suitable medium such as a polymer could provide a better platform for practical applications via thin-film or coating nanotechnology. ,− …”
