Nowadays, different types of strategies are proposed and tested to find the best scenario for upgrading the productivity of heat transfer fluids, especially nanofluids. Some optimum empirical conditions demonstrated that the best size, shape, and nature of nanoparticles and their appropriate dispersion have positive influences on nanofluid thermal conductivity improvements. Therefore, the specific physicochemical properties of the base fluid can be taken into account as one of the decisive factors in heat transfer operations. Deep eutectic solvents (DESs) are nominated as valuable materials to meet the demands for sustainable ecological processes and open opportunities for overcoming the limitations of conventional fluids.The purpose of this study is to briefly introduce the DESs for evaluating their thermal potential applicability and their use to produce nanofluids. DES-based nanofluids represent a new and creative type of heat transfer fluids that possess high potential in different target applications and are not harmful to the environment. This type of nanofluid has higher thermal properties than the base DESs. Increasing the temperature and the volume fraction of nanoparticles lead to further increment in their thermal properties. In this study, the chemical structure and preparation method have been addressed for the DES and DES-based nanofluids. Also, the theoretical approaches have been considered for modeling and predicting their behavior. A discussion was extended to investigate the usage of DES as host fluid for producing nanofluids, and its advantages and drawbacks are also presented. It is deduced that the DES-based nanofluids are one of the smart choices for the progression of nanofluids and give the most promising results for application in heat transport fluids. The contents may shed light on a detailed awareness of the heat transfer potential of the DESs.

“…Dehury et al 15 reported the thermal conductivity measurement of the DES dispersed with the alumina-based nanoparticle, proving that it can be used as a potential solar storage medium. To investigate the possibility of using DES as a heat-transfer fluid, Siong et al 24 prepared DESbased nanofluids by a two-step method. They found that if the temperature has increased, the nanofluids based on DES with water showed greater improvement in thermal conductivity than the pure DES-based approach.…”

In this work, the thermal conductivities of l-menthol–decanoic acid (Men–DecA) deep eutectic solvents were measured with different mole compositions using a transient hot-wire method. The measured temperature range was 283.15–363.15 K, and the pressure was up to 15.1 MPa. The relative expanded uncertainty of the obtained data was estimated to be ±2% with a confidence level of 0.95 (k = 2). The linear thermal conductivity model was used to correlate the experimental data as a function of the mole fraction of decanoic acid, temperature, and pressure. The average absolute relative deviation and the maximum absolute relative deviation between the experimental values and the calculated results from the model were 0.27 and 1.26%, respectively.

“…31 Moreover, the fibrous structure of PANI has been synthesized via oxidative polymerization as reported in the literature. 16,22,29,31 Siong et al have also shown the increment in thermal conductivity 4.67% with a weight fraction of 0.2% using dodecylbenzenesulfonic acid (DBSA)-doped PANI-based ionic NFs at a temperature of 50 C. 32 The limited work on the PANI-based NFs has shown that the research is still on its way as the colloidal stability, pressure losses and PP aspects were not explored much. These aspects play a vital role in longterm operation of HTFs and are the decisive factors required in the process design.…”

Summary In this study, polyaniline (PANI) nanocomposite‐based nanofluids (NFs) in ethylene glycol were obtained with a two‐step method by varying volume concentrations from 0.005% to 0.02%. Tungsten disulphide (WS2) nanoparticles were doped in PANI having different weight percentage (1%, 2% and 5%) via oxidative in situ polymerization employing ammonium persulphate oxidant in an acidic environment. The nanocomposites were comprehensively characterised using various techniques, such as Fourier transform infrared spectroscopy, thermogravimetric analysis, field emission scanning electron microscopy and high‐resolution transmission electron microscopy. The formulated NFs were extensively investigated with zeta‐sizer, particle size analyzer, thermal property analyzer and rheometer in a temperature range of 25°C to 70°C. The zeta potential results (up to 54.5 mV) were evident of extraordinary stability of NFs at all targeted temperatures along with polydispersity index <30% and mean particle/agglomerate size in the range of 335.8 to 489 nm. Additionally, a remarkable thermal conductivity improvement (~20.7%) was achieved with intrinsic PANI‐based NFs at an operating temperature of 50°C. Subsequently, it varied substantially with WS2 doping within PANI matrix and reached to 117.9%. Furthermore, the rheological measurements have revealed the viscoelastic nature of NFs along with a remarkable reduction in apparent viscosity (up to 8.4%). The temperature sweep viscosity indicated the transition of relative viscosity from high to low at a critical temperature of about 55°C. The NF10 (WS2 + PANI 5, at 0.005 vol%) was found to be the best candidate with 63.8% thermal conductivity enhancement and 6.4% viscosity reduction as compared with the base fluid at an operating temperature of 50°C. Thus, WS2 doping within PANI has proved to be crucial in the proliferation of thermal conductivity and mitigation of viscosity.
