Special Issue Information

Dear Colleagues,

With nanomaterials gaining a great interest in a wide range of industrial areas, a thorough characterization study of their properties once combined with other materials into nanocomposites remains in the forefront of the materials research field. A better understanding of their behavior in a nanocomposite matrix is imperative for development of new devices for a number of practical applications.

Nanomaterials is relevant to any field of study that involves nanotechnology. All manuscripts undergo a rigorous reviewing process and decisions are made based on the recommendations of independent reviewers. This special issue focuses on the performance and characterization of 2D nanomaterials and nanocomposites for designing novel devices. We invite authors to contribute research articles on the multidisciplinary research area on nanocomposite-based devices including but not limited to:

  • Synthesis and characterization of carbon nanomaterials
  • Carbon nanomaterials in energy conversion and storage
  • Nanomaterials in catalysis
  • Nanomaterials in sensors
  • Nanocomposites
  • Nanoelectronic devices
  • Optoelectronic devices
  • Chemical sensing devices
  • Nanocomposite-based devices

Recent advances in nanoscience have opened ways of recycling substrates for nanomaterial growth. Novel materials, such as atomically thin materials, are highly desirable for the recycling substrates. In this work, we report recycling of monolayer graphene as a growth template for synthesis of single crystalline ZnO nanowires. Selective nucleation of ZnO nanowires on graphene was elucidated by scanning electron microscopy and density functional theory calculation. Growth and subsequent separation of ZnO nanowires was repeated up to seven times on the same monolayer graphene film. Raman analyses were also performed to investigate the quality of graphene structure along the recycling processes. The chemical robustness of graphene enables the repetitive ZnO nanowire growth without noticeable degradation of the graphene quality. This work presents a route for graphene as a multifunctional growth template for diverse nanomaterials such as nanocrystals, aligned nanowires, other two-dimensional materials, and semiconductor thin films.

A novel composite based on a polymer (P(VDF-TrFE)) and a two-dimensional material (graphene flower) was proposed as the active layer of an interdigitated electrode (IDEs) based humidity sensor. Silver (Ag) IDEs were screen printed on a flexible polyethylene terephthalate (PET) substrate followed by spin coating the active layer of P(VDF-TrFE)/graphene flower on its surface. It was observed that this sensor responds to a wide relative humidity range (RH%) of 8–98% with a fast response and recovery time of 0.8 s and 2.5 s for the capacitance, respectively. The fabricated sensor displayed an inversely proportional response between capacitance and RH%, while a directly proportional relationship was observed between its impedance and RH%. P(VDF-TrFE)/graphene flower-based flexible humidity sensor exhibited high sensitivity with an average change of capacitance as 0.0558 pF/RH%. Stability of obtained results was monitored for two weeks without any considerable change in the original values, signifying its high reliability. Various chemical, morphological, and electrical characterizations were performed to comprehensively study the humidity-sensing behavior of this advanced composite. The fabricated sensor was successfully used for the applications of health monitoring and measuring the water content in the environment. Full article
