The scientific community maintains considerable interest in polyvinyl alcohol (PVA) based on metal oxide nanocomposites due to its ability to combine both polymers and dopants with their properties. [1-15] These polymers have many applications in medical and engineering technology because of their mechanical, electrical, and optical properties. [16,17] ZnO-based polymeric nanocomposite materials have attracted scientific attention because of their transparency, high electron mobility, wide bandgap (3.2 eV, at 300 K [18,19]), and electrical properties. The insertion of ZnO nanoparticles into PVA matrices, in general, may significantly change their electric, mechanical, and optical characteristics. [1,7,8,15] PVA is readily water-soluble, and as such has many uses in the fields of polymer processing, pharmacy, and biomedicine. [20-23] Shanshool et al. [7] have studied the optical properties of various composites that use ZnO nanoparticles as a filler material in different polymer matrices, such as poly(methyl methacrylate) (PMMA), poly(vinylidene fluoride) (PVDF), PVA, and polystyrene (PS). ZnO nanoparticles have been found to have an effect on the bandgap of each polymer matrix, depending on the polymer's nature. The structural, optical, and dielectric properties of ZnOreinforced poly(ethylene oxide) (PEO) blended with poly(vinyl pyrrolidone) (PVP) have been previously studied by Choudhary.

Poly(ethylene terephthalate) (PET) was synthesized by two steps, namely (a) transesterification and (b) polycondensation. Various analytical instruments were used for the characterization of neat PET. The sodium salt of nucleating agents added with PET was synthesized by the in‐situ method under the same experimental conditions. The influence of CO2Na, ONa, SO3Na, PO3Na on the crystallization properties of PET was tested. The aromatic SO3Na nucleated PET exhibited the highest crystallization temperature (Tc) value of 211.4°C with the degradation temperature (Td) value of 446.9°C. The energy of activation (Ea) for the degradation and crystallization of PET was determined using various kinetic models. The modified Avrami equation showed the 3D crystal growth of PET, which was further evidenced by polarized optical microscopy (POM). The second stage of degradation consumed a higher amount of thermal energy. The experimental results were compared with the literature values.

Food packaging film is being developed using biodegradable polymers to prolong the shelf life of foods and address the environmental damage caused by non‐biodegradable plastics. Poly(vinyl alcohol) (PVA) is a biodegradable polymer with outstanding characteristics and can be easily shaped into a film. However, PVA‐based film still faces several obstacles that seriously restrict its practical application in the food packaging industry, particularly its low thermal stability limits the film process method. The growing preference demand for PVA‐based films with enhanced thermal stability in food packaging can be attributed to their advantageous characteristics, including commendable temperature resistance, safety, versatile processing capabilities, and prolonged shelf life. It is critical to comprehend the difficulties with PVA thermal degradation behavior and mechanism, and how to address this problem. In this review, we provide strategies for improving the thermal stability of PVA film including modification with environmentally friendly polymers, nanoparticles, and crosslinking agents. Also, the current challenges, and the potential for future advancements in the thermal stability of PVA and its composites are proposed. The new insight into the relationship between PVA based film processing and thermal properties of materials are expected to provide a valuable guide for developing PVA films with high thermal stability.
