“…Some of the researchers applied all of these methods to gain better stability [28][29][30] but others just applied one [31] or two techniques [32][33][34] with satisfaction. There is no standard to recognize the superlative mix up of combining methods.…”

“…This can be overcome by subjecting them to ultra-sonification [12,13]. Besides, adding surfactant or activator to modify the hydrophobic surfaces of nanoparticles to become hydrophilic for aqueous and vice versa can also be used for non-aqueous [14,15]. In addition, pH control can create a strong repulsive force that can stabilize a well-dispersed suspension [16,17].…”

Nanofluid has attracted great attention due to its superior thermal properties. In this study, chemical oxidative polymerization of aniline was carried out in the presence of dodecylbenzenesulfonic acid (DBSA) as a dopant. Particles of DBSA-doped polyaniline (DBSA-doped PANI) with the size range of 15 to 50 nm were obtained, as indicated by transmission electron microscope (TEM). Results of ultra violet-visible (UV-Vis) absorption and Fourier transform infrared (FTIR) spectroscopies as well as thermogravimetric analysis showed that PANI nanoparticles were doped with DBSA molecules. The doping level found was 36.8%, as calculated from elemental analysis data. Thermal conductivity of water was enhanced by 5.4% when dispersed with 1.0 wt% of DBSA-PANI nanoparticles. Specific heat capacity of water-based nanofluids decreased with increasing amount of DBSA-PANI nanoparticles.

“…In this study, DBSA-PANI nanoparticles acted as surfactant and dopant [3]. DBSA modified the surface of nanoparticles and improved the stability of nanofluids [2,7] while water played as another hydrogen bond donor in this case [10,18]. Interaction of dopants and DES ions was also revealed to contribute to enhancement in thermal conductivity of DES based nanofluids.…”
