A comparative experimental study on the physical behavior of mono and hybrid RBD palm olein based nanofluids using CuO nanoparticles and PANI nanofibers

A new class nanofluid consisting of Copper Oxide (CuO) nanoparticles, Polyaniline Nanofibers (PANI), and CuOPANI nanocomposites dispersed in refined, bleached, and deodorized palm olein (RBDL) base fluids have been successfully prepared. The prepared nanofluids were physically characterized to inv...
