“…The films shown here have a preferable strength and toughness versus most lignocellulosic films (Figure 6b). 6,[28][29][30]42,43 The mechanical strength of cellulose films prepared via physical methods was mainly affected by the entanglement and hydrogen bonds. The ultrasonic treatment led to microfibril fibrillation, which exposes a larger specific surface area and further forms a denser cellulose network with a micro-and nanoscale hierarchical structure (Figure S7).…”

“…Lignin is the second-most abundant renewable biopolymer and is the most abundant aromatic compound in the world. Lignin has natural ultraviolet barrier properties because of its phenolic hydroxyl and ketone groups. , Therefore, our goal here was to prepare a biodegradable and sustainable micro/nano cellulose film with excellent optical properties and endow it with UV resistance by using lignin.…”

Light-management materials play a great significant role in efficient-energy buildings because they reduce indoor energy consumption by adjusting to natural sunlight, enhancing heat insulation, and creating comfortable indoor lighting. Here, we fabricated an ecofriendly and sustainable lignocellulose-based light-management film via a facile homogenization and mechanical hot-pressing method without complicated treatment or toxic reagents. The resulting film exhibited a favorable ultraviolet (UV) blocking performance of 82.25% for UVA, high visible light transmittance, and high haze, with a desirable tensile strength of 197 MPa, which was significantly higher than those of most petroleum-based plastics. Accordingly, the film was further endowed with near-infrared absorption performance by spray-coating with lanthanum hexaboride (LaB6) nanoparticlesthere were almost no adverse effects on its light transmittance or mechanical strength. Meanwhile, the high haze of the film implied that it met the requirement for privacy protection in smart buildings. The MFC/lignin/LaB6 composite film has potential applications in energy-saving buildings and optoelectronic devices.

“…ECH is a typical hydroxyl cross-linking agent, and the above results indicated that ECH could combine the components tightly to reduce the exposed hydroxyl groups and decrease the availability of hydroxyl groups to react with water molecules ( Ma et al, 2022 ); thus, the swelling ratio of the composite films decreased. The swelling property of ECH cross-linked composite films agreed well with Ma et al ( Ma et al, 2022 ) who reported the development in the water resistance of ECH cross-linked cellulose/glucomannan/lignin composite films. From Figure 5I , however, the swelling ratio of the composite films developed from 91.64% to 142.54% by increasing ε-PL content from 10% to 50%.…”

Cellulose-based functional composite films can be a good substitute for conventional plastic packaging to ensure food safety. In this study, the semi-transparent, mechanical strengthened, UV-shielding, antibacterial and biocompatible films were developed from hydroxyethyl cellulose Polyvinyl alcohol (PVA) and ε-polylysine (ε-PL) were respectively used as reinforcing agent and antibacterial agent, and chemical cross-linking among these three components were constructed using epichlorohydrin The maximum tensile strength and elongation at break were 95.9 ± 4.1 MPa and 148.8 ± 2.6%, respectively. TG-FTIR and XRD analyses indicated that chemical structure of the composite films could be well controlled by varying component proportion. From UV-Vis analysis, the optimum values of the percentage of blocking from UV-A and UV-B and ultraviolet protection factor values were 98.35%, 99.99% and 60.25, respectively. Additionally, the composite films exhibited good water vapor permeability, swelling behavior, antibacterial activity and biocompatibility. In terms of these properties, the shelf life of grapes could be extended to 6 days after packing with the composite film.

“…Recently, the usage of lignin as an additive for preparing polyvinyl alcohol (PVA)-based films has emerged as a method of using lignin in the material context. By simply adding lignin to PVA gels, the obtained films can exhibit higher mechanical strength and UV-shielding properties ( Posoknistakul et al, 2020 ; Zhang et al, 2020 ; Ma et al, 2022 ). However, in identical practice, commercial lignin needs to be obtained as another co-ingradient.…”

The conversion of lignocellulosic biomass into various high-value chemicals has been a rapid expanding research topic in industry and agriculture. Among them, alkaline removal and utilization of lignin are important for the accelerated degradation of biomass. Modern biorefinery has been focusing the vision on the advancement of economical, green, and environmentally friendly processes. Therefore, it is indispensable to develop cost-effective and simple biomass conversion technologies to obtain high-value products. In this study, the black liquor (BL) obtained from the alkaline pretreatment of biomass was added to polyvinyl alcohol (PVA) solution and used to prepare degradable ultraviolet (UV) shielding films, achieving direct and efficient utilization of the aqueous phase from alkaline pretreatment. This method avoids the extraction step of lignin fraction from black liquor, which can be directly utilized as the raw materials of films preparation. In addition, the direct use of alkaline BL results in films with similar UV-shielding properties, higher physical strength, and similar thermal stability compared with films made by commercial alkaline lignin. Therefore, this strategy is proposed for alkaline-pretreated biorefineries as a simple way to convert waste BL into valuable products and partially recover unconsumed sodium hydroxide to achieve as much integration of biomass and near zero-waste biorefineries as possible.
