“…However, when employing bio-based nanocomposites in packaging applications, the decrease in transmission of UV-Vis radiation through the material is advantageous since UV and visible light can have a detrimental impact on the quality of food products. and biopolymer-based nanocomposite films [1,25,29]. In this study, the influence of CNC on the thermal degradation of nanocomposites was evaluated using the TGA/DTG curves.…”

“…In recent years, an increasing interest in biodegradable or sustainable polymers and environmentally friendly materials as a whole has been generated by current concerns about environmental pollution and the decreasing availability of petroleum [1,2]. Consequently, biopolymers have caught the interest of academics due to their potential applications in a variety of industries, including food packaging, pharmaceuticals, the automobile industry, and cosmetics [3][4][5].…”

“…Polyvinyl alcohol (PVA) is a basic linear hydrophilic synthetic polymer containing hydroxyl pendant groups and is commercially manufactured from polyvinyl acetate [11]. PVA is used in a wide range of industrial and packaging applications because of its film-forming properties, optical transparency, biodegradability, high crystallinity, and mechanical properties [1,16]. In general, PVA is one of the widely available synthetic polymers and has a relatively low manufacturing cost and environmental impact [17].…”

In this work, the Juncus plant was used as an abundant and sustainable raw material for the production of cellulose nanocrystals (CNC). Herein, cellulose nanocrystals were prepared via sulfuric acid hydrolysis exhibiting a needle-like shape morphology, with an average diameter of 6.8 ± 1.8 nm and length of 457 ± 76 nm, arising to an aspect ratio of 59. Moreover, X-ray diffraction and TGA show that the CNCs exhibit high crystallinity and good thermal property respectively compared to other sources. Further investigation was conducted by preparing novel bio-nanocomposites through the incorporation of CNCs into the polyvinyl alcohol- alginate (PVA-ALG) blend matrix. Thus, giving enhanced properties compared to the pure matrix, particularly the mechanical properties due to the good interfacial adhesion, confirmed by FTIR analysis, while maintaining good transparency at low CNCs concentration, which is required for packaging application.

“…As a result, these packaging materials must be biodegradable (Cheng et al, 2021). Many governments have largely overcome this problem by implementing technology solutions while emerging and poor countries continue to face considerable challenges (Andrade et al, 2022;Xu et al, 2021). The environment's resilience to deterioration is putting health, biodiversity, and agriculture in jeopardy (Iqbal, 2020;Irfan et al, 2021;Irfan, Tahir, et al, 2020;Irfan, Wang, et al, 2020).…”

Grafting of starch with methyl methacrylate was carried out using a free radical mechanism. Free radicals were generated by the thermal disintegration of potassium persulphate at the temperature of 60 C. A variety of experimental methods were investigated to check the effect of different parameters such as (temperature, amount of starch, quantity of monomer) for efficient grafting. The optimum temperature found for good grafting was 60 C. The initial amount of starch was taken as 0.75 g. Keeping the amount of starch constant, the quantity of monomer was reduced gradually from 10 to 2 ml in portions of 5 and 3 ml. The controlled biodegradability of the grafted product was obtained by using a 3 ml monomer in 0.75 g starch. This grafted polymer showed 31.45% biodegradability in 60 days. The nanocomposite of starch grafted methyl methacrylate was prepared by incorporating 0.02 g Ni nanoparticles in the reaction flask 15 min before the completion of reaction time. The starch grafted polymer and nanocomposite of this were fully characterized by SEM, FTIR, TGA, and DSC techniques. The soil burial method was applied to estimate the biodegradability of samples. The polymer containing Ni nanoparticles was less biodegradable than without nanoparticles. Such polymers can be efficiently used as packaging material for food items. Research Highlights1. Through a free radical method, methyl methacrylate was grafted onto the backbone of starch in this study.2. During the process, nickel nanoparticles were added to achieve the nickel nanocomposite of the starch grafted polymer.3. The breakdown of starch grafted polymer after 60 days in a soil burial experiment was 31.45%, whereas the degradation of nanocomposites was 20.07%. 4. Our synthesized nanocomposite polymers can be effectively employed as packaging material for food items.
