“…In Figure 6, we plotted mode of size distribution and viscosity (measured at a shear rate of 100 s −1 ) in different samples, and we can observe that the trends are almost overlapping. The only slight exception is the sample LNF/5 compared to the sample The complexity of size distribution analysis of nanofibers in this work comes as a consequence of two effects: first, the nanofibers without ZnO are formed in such a way that PEO envelopes the CA, which leads to the effect of several CA nanofibers being enveloped by PEO [39], and the addition of ZnO in polymer solution disrupts the CA-PEO system, which is reflected in the observed change in viscosity.…”

“…Solution blow spinning was performed using a homemade device at UC3M as reported previously [39,40]. The distance from the tip of the needle to the collector (working distance) was set to 15 cm, the rotational speed of the collector was 250 rpm, the pressure of the propellent air was 1.5 bar for the LNF mixtures and 2 bar for the HNF mixtures, and the injection rate (IR) was set at 0.25 mL/min.…”

“…In this paper, we present incorporation of ZnO nanoparticles into cellulose acetatepoly(ethylene oxide) CA-PEO nanofibers. The use of PEO during spinning plays a supporting role in CA spinning [39], since CA is difficult to process using SBS, because of the inability to obtain bead-free nanofibers [40]. Both polymers, CA and PEO, are biodegradable and biocompatible, which makes them suitable for potential biomedical applications, especially considering the bioactivity of ZnO [31].…”

In this work, the preparation and characterization of composites from cellulose acetate (CA)–poly(ethylene oxide) (PEO) nanofibers (NFs) with incorporated zinc oxide nanoparticles (ZnO-NPs) using solution blow spinning (SBS) is reported. CA–PEO nanofibers were produced by spinning solution that contained a higher CA-to-PEO ratio and lower (equal) CA-to-PEO ratio. Nanoparticles were added to comprise 2.5% and 5% of the solution, calculated on the weight of the polymers. To have better control of the SBS processing conditions, characterization of the spinning suspensions is carried out, which reveals a decrease in viscosity (two- to eightfold) upon the addition of NPs. It is observed that this variation of viscosity does not significantly affect the mean diameters of nanofibers, but does affect the mode of the nanofibers’ size distribution, whereby lower viscosity provides thinner fibers. FESEM–EDS confirms ZnO NP encapsulation into nanofibers, specifically into the CA component based on UV-vis studies, since the release of ZnO is not detected for up to 5 days in deionized water, despite the significant swelling of the material and accompanied dissolution of water-soluble PEO. Upon the dissolution of CA nanofibers into acetone, immediate release of ZnO is detected, both visually and by spectrometer. ATR–FTIR studies reveal interaction of ZnO with the CA component of composite nanofibers. As ZnO nanoparticles are known for their bioactivity, it can be concluded that these CA–PEO–ZnO composites are good candidates to be used in filtration membranes, with no loss of incorporated ZnO NPs or their release into an environment.

Perishable food post-harvest loss is a major global concern, and research is currently concentrated on creating active packaging materials. This research is focused in multiple antioxidants intercalated Layered Double Hydroxides (LDH) that are combined in one matrix, and their overall effect that defines as synergism, which successfully preserves perishable food by releasing antioxidants slowly. For this purpose, a hybrid LDH material of ascorbic-LDH, salicylic-LDH, and citric-LDH was synthesized, characterized and incorporate into electrospun nanofiber mat to be used as a potential active packaging material. Antioxidants intercalated Mg/Al LDH was synthesized and successfully characterized by PXRD, FTIR, XPS, Raman, SEM and EDS. The shifts in the LDHs' peaks in PXRD indicated the successful incorporation of antioxidants into LDH. FTIR, Raman and XPS data clearly indicated the establishment of metal-oxygen bonds by observing the characteristic peaks. Morphological features and layered structure were clearly observed by SEM images. Antioxidants were slowly released from LDHs, and it was evaluated for time intervals up to 24 hrs. The hybrid LDH material exhibited the highest antioxidant activity with an IC50 value of 132.5µg/mL, where 234.1, 354.5, and 402.2µg/mL were reported for ascorbic-LDH, salicylic-LDH, and citric-LDH respectively. The hybrid LDH material incorporated electrospun mats showed the best antibacterial activity against the tested bacteria and clearly evidenced the synergistic activity of the combination of the nanohybrids. It has showed a minimal bacterial growth compared to other control samples (∼2.41 log CFU/mL). The shelf life of cherry tomatoes was studied at different physiochemical parameters with and without hybrid LDH material incorporated electrospun mats. The mat showed an extended shelf life of 42 days for cherry tomatoes, whereas the control sample showed a shelf life of 17 days. It is concluded that hybrid LDH material exhibited synergistic performance and the best antioxidant activity when comparing with mono LDH materials.
