Abstrakt: •This study explores the structural, optical, and HT traits of HNF in rotating system.•FTIR and UV-Vis spectroscopy reveal the structure, optical behavior, and TPs of NFs.•The energy bandgap decreases from 4.5 eV to 5.3 eV and 4.8 eV for different NFs.•The heat transmission rate of [MgO+ZrO2/PEG-H2O]his 4.58 % higher than of [ZrO2/PEG-H2O]m.•The mass transfer rate of [ZrO2/PEG-H2O]sdrops 3.57 % due to increased activation energy.
