Article Abstract
An edible food packaging gelatin/zein nanofiber film co-loaded with cinnamaldehyde (CA)/thymol (THY) was developed, which possessed outstanding features conducive to strawberries preservation. Firstly, the synergistic antibacterial behavior of CA and THY was investigated. Then CA and THY were co-loaded into gelatin/zein nanofiber films by electrospinning technology. The addition of CA and THY increased water contact angle to 85.1° after 10 s and decreased the water vapor transmission rate of 3.1×10 g·mm·h·Pa. The tensile strength was 1.30 MPa and the elongation at break was 185%. The nanofiber films exhibited good shielding effect of ultraviolet-visible light and excellent antioxidant capacity with DPPH free radical scavenging percentage of 99.9% in 4 h. The nanofiber films (12.5 mg/mL) could achieve significant inhibition effects on Escherichia coli ATCC 25922 with the bacteriostatic ratio of 67.5%, Staphylococcus aureus ATCC 6538 and Listeria monocytogenes ATCC 19115 with the antibacterial ratios of 100%. A real-time study on the nanofiber films as fruit packaging materials was carried out on strawberries and the packaged strawberries kept their freshness as long as 7 days at room temperature. Therefore, the GZ/CT nanofiber film prepared in this work has good application potential in the field of fruit packaging.

Passive Radiant Cooling and Heating are green and sustainable methods of radiant heat management without consuming additional energy. However, the absorption of sunlight and poor insulation of materials can reduce radiative cooling and also affect radiative heating performance. Herein, we have constructed porous hierarchical dual-mode silk nanofibrous aerogel (SNF) films with high mechanical toughness and stability using silk nanofibers/GO.

There is an emerging quest for fabrication of water-soluble fluorescent silver nanoclusters (AgNCs) with long-lasting fluorescent properties and dimensional stability while being sustainable and functional. Thus, a well-known seed-mediated growth strategy has been developed to manufacture AgNCs supported onto carboxyl and aldehyde modified cellulose nanofiber (DATCNF) with ultra-small and intense fluorescence. The DATCNF acts as a reductant, template, and stabilizer while the protective ligand, 2-Mercaptonicotinic Acid (2-HMA), provides AgNCs with luminous characteristic and constrained size of 4.

We investigate the effects of water-processable celluloses on the charge-transport properties in the conducting polymer composites and their solid-state organic electrochemical transistors (OECTs). Water-soluble methyl cellulose (MC) and water-dispersible cellulose nanofiber (CNF) are blended with poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) in solution and used as a conductive channel. Both cellulose-PEDOT:PSS composites show fibrillar structures in thin films with respective dimensions of cellulose.

Degradable and cost-effective cellulose fiber-based materials are ideal substitutes for traditional plastics. However, organic additives used to enhance water and oil resistance often contain toxic substances that may migrate into food, posing health risks. In this study, inspired by tree structures, lignin-containing cellulose nanofibers (LCNFs) are used to form a "crown-roots" structure to enhance the water, oil, and gas resistance, as well as mechanical performance of composites.

In the search of new bioactive and biobased films, the use of lignin nanoparticles (LNP) and cellulose nanofibers (CNF) has gained potential relevance in the last years. In this context, an enzymatic and environmentally friendly pretreatment with laccases has been proposed in this work to modify the properties of the developed cellulose-lignin nanocomposite films. Thus, the laccase treatment successfully polymerized kraft lignin as indicated by the increase in weight average molecular weight (from 3621 to 5681 Da) and the reduction in phenol content (from 552 to 324 mg GAE/g lignin).
