ABSTRACT
Fabrication of novel nanofluids from phase change materials, MgO nanoparticles and water for antibacterial, antifungal, thermal energy storage and release applications are also useful in a heating/cooling systems of buildings to prevent the bacterial and fungal presence in water. Also, the prepared nanofluids have high quality for thermal energy storage and release for heating/cooling. The (PVP-PEG-MgO-H2O) nanofluids are prepared with different concentrations of (polyvinyl pyrrolidone (PVP 50 wt.%) –polyethylene glycol (PEG 50 wt.%) and magnesium oxide nanoparticles were added to polymer blend fluids with different weight percentages of (0, 4, 8 and 12) wt.%. The optical and thermal properties of (PVP-PEG-MgO-H2O) nanofluids have been studied. The results showed that the absorbance of (PVP-PEG-H2O) fluid increases and the transmittance decreases with increase of the MgO nanoparticles’ concentrations. The thermal conductivity of (PVP-PEG-H2O) fluid increases with increase of the MgO nanoparticles’ concentrations. The antibacterial and antifungalproperties of (PVP-PEG-MgO-H2O) nanofluids were tested against aspergillus, bacillus, lactose, streptococcus and pseudonymous organisms. Results showed that the (PVP- PEG-MgO-H2O) nanofluids have high activities for antibacterial and antifungal. The inhibition zone diameter increases with increasing of magnesium oxide nanoparticles’ concentrations. Also, the (PVP- PEG-MgO-H2O) nanofluids tested for storage of energy and release; the results showed the time of melting and solidification are decreased with increase of the MgO nanoparticles’ concentrations. The (PVP- PEG-MgO-H2O) nanofluids have high activities for antibacterial and antifungal. The (PVP-PEG-MgO-H2O) nanofluids have high quality for thermal energy storage and release which can be used for heating-cooling of buildings, automobile engines etc.
