“…In composite materials, PVA is frequently utilized as a polymer matrix, and CS is frequently employed as a reinforcing agent in an effort to broaden the application of PVA in the field of high-strength materials [ 26 , 38 ]. Thus, the co-existence of the hydroxyl groups in both PVA and CS, doubled by the presence of amino groups in CS, can produce intermolecular interactions, which may result in an improvement of performances of PVA composites.…”

Eco-innovation through the development of intelligent materials for food packaging is evolving, and it still has huge potential to improve food product safety, quality, and control. The design of such materials by the combination of biodegradable semi-synthetic polymers with natural ones and with some additives, which may improve certain functionalities in the targeted material, is continuing to attract attention of researchers. To fabricate composite films via casting from solution, followed by drying in atmospheric conditions, certain mass ratios of poly(vinyl alcohol) and chitosan were used as polymeric matrix, whereas TiO2 nanoparticles and a polyphosphonate were used as reinforcing additives. The structural confirmation, surface properties, swelling behavior, and morphology of the xerogel composite films have been studied. The results confirmed the presence of all ingredients in the prepared fabrics, the contact angle of the formulation containing poly(vinyl alcohol), chitosan, and titanium dioxide in its composition exhibited the smallest value (87.67°), whereas the profilometry and scanning electron microscopy enlightened the good dispersion of the ingredients and the quality of all the composite films. Antimicrobial assay established successful antimicrobial potential of the poly(vinyl alcoohol)/chitosan-reinforced composites films against Staphylococcus aureus, Methicillin-resistant Staphylococcus aureus (MRSA), Escherichia coli, Pseudomonas aeruginosa, and Candida albicans. Cytotoxicity tests have revealed that the studied films are non-toxic, presented good compatibility, and they are attractive candidates for packaging applications.

“…Other metal and oxide metal NPs compounds have shown increased potential for application as antimicrobial agents in food packaging, such as gold (Au) NPs (Hameed et al., 2020; Virgili et al., 2021), selenium (Se) (Ndwandwe et al., 2021), NiO (Ali et al., 2021; Saleem et al., 2017), Cu 2 O (Jaramillo et al., 2019; Yan et al., 2021), Al 2 O 3 (Tavakolian et al., 2021; Yakdoumi & Hadj‐Hamou, 2020), Fe 3 O 4 (Gabrielyan et al., 2019; Saedi et al., 2021b), α‐Fe 2 O 3 hematite (Dash et al., 2020; Vihodceva et al., 2021), γ‐Fe 2 O 3 maghemite (Luengo et al., 2020; Rana et al., 2019), and FeMnO 3 (Vasiljevic et al., 2020). In addition, carbon‐based nanomaterials including graphene oxide (GO), CNT, fullerene, pure detonated nanodiamond (DND), and modified nanodiamond NPs have been used in the preparation of reinforced nanocomposites for various food applications (Mitura et al., 2021; Sobhan et al., 2020; Vieira et al., 2020b).…”

“…Additionally, CS‐based films are excellent barrier materials that prevent oxygen from entering the food, inhibiting respiratory activity and the growth of bacteria in the food (Nouri et al., 2018). Lately, various CS‐based film manufacturing methods have been reported, including coating, solvent casting, extrusion, layer‐by‐layer assembly, electrospinning, among others (Pandey et al., 2020; Shankar et al., 2021; Yan et al., 2021). Inorganic NPs have been widely added to CS matrices, modifying the characteristics of the composite material, such as mechanical, optical, thermal, barrier properties, antimicrobial, and antioxidant activities (Lan et al., 2021; Zhan et al., 2021).…”

Inorganic nanoparticles (NPs) and natural antioxidant compounds are an emerging trend in the food industry. Incorporating these substances in biobased and biodegradable matrices as polysaccharides (e.g., starch, cellulose, and chitosan) and proteins has highlighted the potential in active food packaging applications due to more significant antimicrobial, antioxidant, UV blocking, oxygen scavenging, water vapor permeability effects, and low environmental impact.

“…The electrical and optical properties of a conducting polymer could be altered by doping metal oxides to it. There have been many studies reported on metal oxide doped polymer nanocomposites with dopants such as CuO, ZnO, Cu 2 O, MnO 2 , ZrO 2 ,TiO 2 and SnO 2 [12][13][14][15][16][17][18]. Copper Oxide is blackish brown in color and has monoclinic structure.…”

Polycarbazole (PCz) has been synthesized by chemical oxidation method using APS as an oxidizing agent and PCz/CuO and PCz/Fe2O3 nanocomposites by in situ polymerization method for different wt% of CuO and Fe2O3 at room temperature. XRD patterns confirmed crystalline nature of samples. FTIR indicated strong interaction between PCz and nano fillers. The morphological and optical absorption studies were carried out using SEM and UV-Vis respectively. Addition of CuO or Fe2O3 to PCz decreased its direct and indirect band gaps. However, band gap showed a small change with dopant contents up to 30%. Urbach energy decreased with the addition of dopants. But Urbach energy of the composites increased with increasing dopants content from 10 to 30%. DC conductivity of PCz and its nanocomposites has been measured by following two probe technique in the temperature range from 300 K to 423 K. he conductivity of both the nanocomposites is found to be less than the pure PCz and it is found to increase with wt% of CuO or Fe2O3 as the case may be. The activation energy has been determined by fitting Arrhenius expression to the dc conductivity data at high temperature. The activation energy of polycarbazole is determined to be less than that of the composites. In both the composites, activation energy decreased and conductivity increased with the increase of dopant content.
