“…[19] Although effective, it consumes some of the functional groups of the cross-linked polymer and thus limits the functionality of the PVA for being used in water treatment applications. Therefore, various materials have been incorporated into PVA to improve its adsorption performance to water pollutants such as β-maltodextrin, [20] starch, [21] chitosan, [22] kappacarrageenan, [23] alginate, [24,25] poly (diallyldimethylammonium chloride), [26] agar, [27] cellulose, [28] biomass, [29] and inorganic fillers. [30][31][32] Despite these materials showed a high adsorption efficiency in removal of water pollutant, most of them exhibited a low adsorption efficiency for anionic dye.…”

[20,25,27,33] Therefore, the present work focuses on developing an effective eco-friendly film based on PVA and PAMAM dendrimers for anionic dye removal using a chemical cross-linker, epichlorohydrin (EPI). In recent years, dendrimers, particularly PAMAM, has been emerged as an effective adsorbent for heavy metal ions and oily saline wastewater.…”

The dye-water treatment by polyvinyl alcohol (PVA) is still a challenge as PVA is characterized by its strong affinity to water. Therefore, this study aims to fabricate a functional PVA film with good regeneration ability to remove anionic dyes from aqueous solution using polyamidoamine dendrimers (PAMAM) as a modifier and epichlorohydrin as a cross-linker. Solution casting technique was applied to prepare the functionalized film. The adsorption efficiency of the film was evaluated by studying the effect of various parameters such as PAMAM loading (0, 12.5, 25, 50 wt%), initial dye concentration, film dose, solution pH, and adsorption time. The adsorption studies showed that with increasing PAMAM loading, the maximum adsorption capacity of the resulting film increased till it reached up to 73.8 mg/g by the PVA film with 50 wt% PAMAM. For understanding the nature of the adsorption process of the prepared film, the kinetics and isotherm analysis were studied. It was found that the mechanism of dye removal by the prepared film followed pseudo-secondorder kinetic and Freundlich isotherm, respectively. The adsorption and regeneration studies indicated that this film has great potential to effectively remove anionic dye from wastewater.

This work is to produce multi‐functional active film from polyvinyl (alcohol)/chitosan (PCs) supplemented with Sonneratia ovata leaf extract (SOE) and Piper betel L. oil (PBLO). Our finding showed yellowish SOE‐added PCs film with the compact structure possessing lower swelling degree (SD) (22.48%) and higher mechanical strength (5.05 MPa) as compared to the neat PCs (35.43% and 3.18 MPa, respectively). While the co‐supplementation with PBLO at different ratios significantly increased SD between 50.97% and 104.08% due to the more open structure. UV‐barrier, antimicrobial, and antioxidant properties of PCs film were significantly revitalized with co‐supplementation of SOE and PBLO. The PCs/SOE1/PBLO0.5 film presented better force resistance (5.51 MPa) and flexibility (87.12%) than other film formulations with balanced antibacterial and antioxidant properties and hence, it was further applied for preserving fresh‐cut beef for 14 days at 4°C. Changes in visual appearance, drip loss, and pH of fresh‐cut beef during storage period indicated better protective efficacy of PCs/SOE1/PBLO0.5 film as compared to polyethylene (PE), PCs, and SOE‐added PCs materials, suggesting its promisingly potential for food packaging application.

The present work aims to develop active and biodegradable coating from polyvinyl alcohol (PVOH), agarose, and D‐glucose combined with Sonneratia ovata leaf extract (SO) for prolonging the shelf life of Grande Naine banana. In addition, the PVOH/agarose/D‐glucose/SO coating films were prepared through solvent evaporation method before applying it to banana for the purpose of characterizing vital properties required for food packaging materials. Our findings showed that the addition of SO in the polymer blend based on PVOH/agarose/D‐glucose (PAD) imparts outstanding flexibility, UV‐barrier, antioxidant, and bactericidal properties of the resultant film. It was also found that the modified coatings with SO could prolong the shelf life of bananas up to day 6th storage at 25°C. The visual appearance, development of peel color, weight loss, total soluble sugar content, and pH of banana samples confirmed that PAD‐SO coating could prevent ripening of bananas during the storage period as compared to uncoated and PAD‐coated fruits. These results suggest that PAD‐SO active coatings are a promisingly potential material for extending the shelf life of fruits.
