Area of Science:

  • Materials Science
  • Nanotechnology
  • Heat Transfer

Background:

  • Developing thermally stable nanofluids for heat transfer applications is challenging.
  • Existing nanofluids often degrade at elevated temperatures, losing performance.
  • Graphene oxide (GO) nanofluids face stability issues due to surface group reduction.

Purpose of the Study:

  • To investigate the thermal conductivity, rheological properties, and thermal stability of hexagonal boron nitride nanosheets (h-BNNSs) in ethylene glycol (EG).
  • To compare the performance and stability of h-BNNS/EG nanofluids against graphene oxide (GO) nanofluids.
  • To evaluate the potential of h-BNNSs as a stable alternative for heat transfer fluids.

Main Methods:

  • Synthesis and characterization of two-dimensional (2D) hexagonal boron nitride nanosheets (h-BNNSs).
  • Preparation of h-BNNS/EG and GO/EG nanofluids at various concentrations.
  • Measurement of thermal conductivity, rheological properties, and long-term thermal stability at elevated temperatures (up to 90 °C).

Main Results:

  • Hydroxyl functional groups on h-BNNSs ensured excellent dispersion and compatibility in EG up to 90 °C.
  • h-BNNS/EG nanofluids showed an 80% enhancement in thermal conductivity at 5 vol% due to the percolation effect of 2D sheets.
  • h-BNNS fluids maintained high thermal conductivity, low viscosity, and electrical insulation for 5 days at 90 °C, unlike GO fluids which degraded.

Conclusions:

  • h-BNNSs offer superior thermal stability and performance in ethylene glycol compared to GO for heat transfer applications.
  • The covalent hydroxyl functionalization of h-BNNSs is key to their stable dispersion and properties at elevated temperatures.
  • h-BNNS/EG nanofluids represent a promising candidate for advanced thermal management systems requiring long-term stability.
