“…The TG profile of the samples containing purified LNPs except for 1% was markedly different to those of the unpurified samples and control sample, which, in turn, were practically superimposable on one another with solely negligible differences able to be observed in the overlaid TG curves. The initial stage of degradation that occurred about 40 °C to 100 °C in the films was assigned to the loss of moisture trapped within the films [ 43 , 44 ]. The corresponding weight losses in the purified LNPs films were considered lost, suggesting that these films had an inherently lower moisture content than unpurified LNPs films and control film.…”

The demand for bioplastic material for industrial applications is increasing. However, moisture absorption and low mechanical strength have limited the use of bioplastic in commercial-scale applications. Macroalgae is no exception to these challenges of bioplastics. In this study, Kappaphycus alvarezii macroalgae were reinforced with lignin nanoparticles. Lignin nanoparticles (LNPs) were used as a filler to reduce the brittleness and hydrophilic nature of macroalgae (matrix). Lignin nanofiller was produced using a green approach from black liquor of soda pulping waste and purified. The physical, mechanical, morphological, structural, thermal, and water barrier properties of LNPs with and without the purification process in macroalgae films were studied. The bioplastic films' functional properties, such as physical, mechanical, thermal, and water barrier properties, were significantly improved by incorporating purified and unpurified LNPs. However, the purified LNPs have a greater reinforcement effect on the macroalgae than unpurified LNPs. In this study, bioplastic film with 5% purified LNPs presented the optimum enhancement on almost all the functional properties. The enhancement is attributed to high compatibility due to strong interfacial interaction between the nanofiller and matrix. The developed LNPs/macroalgae bioplastic films can provide additional benefits and solutions to various industrial applications, especially packaging material.

“…In fact, UV light penetration through the packaging material creates free radicals, increasing food degradation rate and reducing shell life. 18 The incorporation of LPs in chitin nanofiber networks and respective electrostatic interactions are expected to prevent particle leakage, which is key with regards to food safety. As the interactions between lignin and chitin prevent any LP leakage, this system could also be of interest for drug release applications.…”

“…The polyphenolic nature of lignin leads to interesting photocatalytic effects, such as UV shielding and antioxidant activity, which are especially relevant for food packaging considering that light is very detrimental for food. 18 Lignin colloids have also been explored in sunscreens applications 19 and recent developments indicate a great promise for nanocellulose in cosmetics. Thus, lignin can bring great benefits if incorporated in fibrillar matrices, especially in the form of nanoparticles which could be exploited to impart improved mechanical performance.…”

Lignin Nanoparticle Nucleation and Growth on Cellulose and Chitin Nanofibers

et al. 2020

Cellulose (CNF) and chitin (ChNF) nanofibers are known to form materials that are both tough and strong. In this study, we hypothesize that the inertness of networks associated to CNF and ChNF makes them ideal templates for heterogenous reaction engineering and to install functionalities by in-situ formation of nanoarchitectures. We expand nanoparticles templating on polysaccharide colloids by introducing a new and facile process that leads to the growth of organic nanoparticles on CNF and ChNF suspended in water. The process based on solvent shifting supported on solid interfaces is demonstrated by direct observation and exploits the photocatalytic effect of lignin nanostructures. Importantly, the dynamics of nanoparticles nucleation and growth is correlated to the surface chemistry of the templates. Electrostatic repulsion between the deprotonated lignin molecules and the slightly negative CNF support led to limited adsorption and, therefore, was effective in producing free (non-bound) lignin nanoparticles (28±7 nm) by precipitation. In contrast, the stronger interfacial interactions between the positively charged ChNF and lignin molecules led to instantaneous and extensive lignin adsorption, followed by nucleation and growth into relatively larger nanosphere (46±17 nm). The latter were homogeneously distributed and strongly coupled to the ChNF support.Overall, we introduce lignin nanoparticle nucleation and growth on renewable nanofibers as an effective route toward in situ synthesis of highly functional fibrils and derived cohesive films that offer great potential in packaging and other areas.

“…16,20,65,66 The high UV and visible light blocking performance of obtained PLA–DCNP films, comparable to that of polymer films containing different additives, enable use of PLA–DCNP films for packaging of many UV and visible light sensitive foods such as meat, vegetable oils, milk, and dairy products. 16,65,67−70 It is worth mentioning that the durability (i.e., color fastness) of the nanopigment under the continuous intense UV exposure was found to be desirable in our previous studies. 20,24…”

High-Strength, Low-Permeable, and Light-Protective Nanocomposite Films Based on a Hybrid Nanopigment and Biodegradable PLA for Food Packaging Applications

2019

Herein, a multifunctional filler, a dye (organic)–clay (inorganic) hybrid nanopigment (DCNP), was embedded into polylactic acid (PLA) to fabricate a colored biodegradable/biocompatible film, which is explored as a high thermomechanical resistant as well as a superior light and mass transport barrier for food packaging applications. In this respect, the DCNP was synthesized through a wet chemical process with a reaction yield of 76% and incorporated into a PLA matrix at various concentrations using a solution casting method. The morphological characterizations revealed partially intercalated/exfoliated structure for PLA–DCNP films. The samples filled with DCNP showed up to 20% and 12 °C improvements in storage modulus (E′) and glass transition temperature (Tg), respectively, compared to those with neat PLA. Incorporation of a small amount of DCNP into the PLA matrix significantly declined the water vapor and gas permeability of PLA by 36 and 54%, respectively. The optical property investigations indicated remarkable color characteristics and light protection performance of the samples containing DCNP. The results also showed better performance of the PLA–DCNP film compared to that of the PLA–Cloisite 20A sample at an identical filler loading. In conclusion, the desirable properties of the resulting films highlighted the potential application of such nanocomposite films as a promising option for food packaging materials.
