“…The construction of reliable alternative materials can also minimize energy consumption for heating, cooling, and air conditioning, thus appreciably reduce both cultivation cost and plant growth periods 4 . The environmental sustainability, mechanical durability, and optical transmittance property of greenhouse covering materials have been studied based on the physicochemical properties of used materials such as additives, fillers, reinforcements, performance, ultraviolet (UV) stabilizers 5–7 …”

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.

“…Nanocomposites have attracted significant research interest during the past decades due to their enhanced electrical, thermal, optical, and mechanical properties . These materials are hybrids of filler and matrix (polymer, metal, and ceramic) where at least one of them is at nanoscale (1–100 nm) . Much effort has been devoted to investigating polymer‐based nanocomposites because polymer possesses several advantages such as lightweight, flexibility, and easy fabrication in comparison with metal and ceramic .…”

“…Nano‐ZnO, with superior refractive index (2.0) and UVA‐shielding capability to nano‐TiO 2 , is a well‐known multifunctional inorganic filler that have unique properties, such as high catalytic activity, strong UV adsorption, and high transparency in the whole visible range, because of its direct and wide band gap of 3.37 eV at room temperature . Moreover, nano‐ZnO exhibits low toxicity, high chemical stability, effective antibacterial properties . Thus many researches have reported on the preparation of multifunctional nano‐ZnO/PMMA composites with UV‐shielding capability, luminescence, photocatalysis even near IR reflectance properties .…”

Multifunctional nano‐ZnO/PMMA composites have wide application prospects in many fields such as antibacterial, photocatalysis, photoluminescence, and UV resistance. For mass production, one‐step in situ polymerization process was employed to prepare nano‐ZnO/PMMA composites, which is simple, environmentally friendly, and economical. The growth of nano‐ZnO was inhibited by PMMA thus nano‐ZnO with small particle sizes of 3–5 nm was dispersed homogeneously in PMMA matrix. Thermal stability and molecular weight of nano‐ZnO/PMMA composites were enhanced obviously in comparison with pure PMMA. Nano‐ZnO/PMMA composites with high visible transparency (91.8% at 600 nm) and efficient UV‐shielding capacity (97.7% at 320 nm) can be used as a substitute for inorganic glass and further extended to optical sensors or optical filters. In addition, the blue‐green luminescence emission under UV light makes nano‐ZnO/PMMA composites a promising candidate for promoting the photosynthesis of plants. POLYM.
