“…The obtained results confirm the suitable performance of the PET4 sample as a greenhouse covering material. The choice of greenhouse covering material is highly dependent on the type of ambient climate 8 . In mild climates, the use of greenhouse covering material with a high value of reflectance in the NIR region is not appropriate during the winter season as it leads to an undesirable increasing the temperature drop and the heating‐loss.…”

In the warm climate, the use of materials with high reflectance helps to control solar radiation flux 8,9 . The high UV protection property of PET1 and PET3 samples can be explained by the wide band‐gap energy of the ZnO NPs and the rutile phase of TiO 2 (3.37 and 3.0 eV for bulk ZnO and rutile TiO 2 , respectively), which makes them an efficient absorber of UV radiation.…”

“…[5][6][7] During past years, the plastic sheets made of lowdensity polyethylene (LDPE), polyolefin (PO), glassreinforced polyester, and polyvinyl chloride (PVC) accounted for a large percentage of the world's greenhouses. 8,9 The benefits of plastic sheets are that they do not require heavy skeletons and reduce heating costs by up to 40% over single-layer glass greenhouses. Most LDPE-based sheets are usually blended with a UV stabilizer agent, extending their durability by up to 3 years.…”

The environmental sustainability, mechanical durability, and thermal stability of the poly(ethylene terephthalate) (PET)-based nanocomposite films compared with pure PET were evaluated. The samples were obtained by incorporating 2 wt% of TiO 2 , SiO 2 , ZnO nanoparticles (NPs), and an equal mixture of NPs in polymer by melt-mixing in a twin-screw extruder. The mechanical properties and hardness of samples were determined by the tensile and the atomic force microscopy-based nanoindentation tests. The melting, crystallization, and glass transition temperatures of samples were studied by dynamic mechanical thermal analysis and differential scanning calorimetry. The effects of compatibility, dispersity, and hydrophobicity of NPs on the surface morphology, crystallinity, and thermomechanical properties of nanocomposites were studied. The interaction of SiO 2 NPs with PET chains had a promising effect on the surface morphology, high elastic modulus, dispersibility, crystallinity, and thermostability of the sample. The mixing of ZnO and TiO 2 NPs improved the UV-blocking effects, and photostability, while the SiO 2 and TiO 2 NPs maintained the thermal properties of the film against UV radiation. The resulting film could be a good candidate as a greenhouse covering material due to its suitable photosynthetically active radiation transmittance.
