“…The peaks at 2θ = 10.5° and 15.1° for CS-15%NDAS disappeared. For gelatin, the signal located at about 2θ = 8.6° corresponds to the inter-helix distance of the triple helix of gelatin, and a broad diffraction peak in the 2θ range of 15.0–25.0 is typical of the amorphous fraction of gelatin [ 68 ]. The obtained pattern is consistent with the literature data [ 69 ].…”

In recent years, new cross-linkers from renewable resources have been sought to replace toxic synthetic compounds of this type. One of the most popular synthetic cross-linking agents used for biomedical applications is glutaraldehyde. However, the unreacted cross-linker can be released from the materials and cause cytotoxic effects. In the present work, dialdehyde starch nanocrystals (NDASs) were obtained from this polysaccharide nanocrystal form as an alternative to commonly used cross-linking agents. Then, 5−15% NDASs were used for chemical cross-linking of native chitosan (CS), gelatin (Gel), and a mixture of these two biopolymers (CS-Gel) via Schiff base reaction. The obtained materials, forming thin films, were characterized by ATR-FTIR, SEM, and XRD analysis. Thermal and mechanical properties were determined by TGA analysis and tensile testing. Moreover, all cross-linked biopolymers were also characterized by hydrophilic character, swelling ability, and protein absorption. The toxicity of obtained materials was tested using the Microtox test. Dialdehyde starch nanocrystals appear as a beneficial plant-derived cross-linking agent that allows obtaining cross-linked biopolymer materials with properties desirable for biomedical applications.

“…Furthermore, ECH is commonly utilized as an coupling agent for removal of bacterial endotoxins, in waste water treatment, drug delivery systems, enzyme immobilization, food packaging, wound healing and many other applications . Once ECH anchorage is accomplished on the surface, then the epoxide surface can readily react with amine groups in basic media such as PEI . Then, these amine‐modified PEI‐HNTs were further protonated with HCl to attain modified H‐PEI‐HNTs and then IL forms of modified HNTs as SDC‐PEI‐HNTs, STFB‐PEI‐HNTs and AHFP‐PEI‐HNTs were created via appropriate anion exchange.…”

Halloysite nanotube (HNT), a natural clay, was modified with branched polyethyleneimine (PEI) to form PEI‐HNT using epichlorohydrin (ECH) as coupling agent, then protonated with HCl to obtain H‐PEI‐HNTs providing [NH3]+[Cl]− functionality for potential antimicrobial properties. Upon PEI modification, zeta potential value of HNTs was increased to +37.3 mV from −34.5 mV and to +41.1 mV for H‐PEI‐HNTs. Only 1.87 wt % H‐element in HNT was increased to 3.03 wt % upon PEI modification along with newly generated elements of N and C at 2.99 and 9.93 wt %, respectively. Moreover, ionic liquid (IL) forms of HNTs with [NH3]+[N(CN)2]−, [NH3]+[PF6]− and [NH3]+[BF4]− functionality were generated via anion exchange of H‐PEI‐HNTs with sodium dicyanamide (SDC), ammonium hexafluorophosphate (AHFP), and sodium tetrafluoroborate (STFB). The antimicrobial properties of the modified, protonated, and IL forms of HNTs were determined via macro dilution, diffusion and agar screening tests against Escherichia coli ATCC 8739, Pseudomonas aeruginosa ATCC 10145, Bacillus subtilis ATCC 6633, Staphylococcus aureus ATCC 6538 strains, and Candida albicans ATCC 10231 strains. It was found that H‐PEI‐HNTs possesses potent antimicrobial effect compared with the other forms of HNTs with 2–4 mg mL−1 MIC and 8–16 mg mL−1 MBC values via the macro dilution method. © 2019 Wiley Periodicals, Inc.

“…As shown in Figure b, a moderately crystalline peak of GBF was observed at around 20.0°. GAF presented a major crystalline peak at 20.6°, indicating that AGO and gelatin were not mixed well in the composite matrix. − From GBAF-1 to GBAF-4, with the amino content of AGO increased, the crystalline peak strength decreased, especially the crystalline peak intensities of GBAF-3 and GBAF-4 were much lower than that of GBF. It demonstrated that AGO with a higher amino group content was dispersed better in the gelatin matrix containing BDA, probably due to the more amorphous cross-linking among BDA, gelatin, and AGO …”

Developing biopackaging materials is a key for environmental, social, and economic sustainability. Herein, a newly designed gelatin composite film was prepared by incorporating biomass-derived aldehyde (BDA) and aminated graphene oxide (AGO), denoted as GBAF. FTIR, XPS, and primary amino group content tests demonstrated the successful preparation of AGO with different amino group contents. FTIR, XRD, and SEM analyses of GBAFs indicated strong interactions among AGO, BDA, and gelatin as well as the uniform dispersion of AGO in the film matrix. TG-DSC analysis showed that the GBAFs had higher thermal stability, and introducing AGO helped to improve the thermal stability of the GBAFs. WVP and gas permeability tests showed that the addition of AGO and BDA into the gelatin film reduced the transmission rate of water vapor, O 2 , and CO 2 , respectively. Additionally, the GBAF prepared from AGO with the highest primary amino content had the best tensile strength (2.45 MPa) due to the rigidity of AGO and covalent cross-linking between gelatin and BDA. Its tensile strength was much higher than that of the composite film without AGO (1.36 MPa) or BDA (1.59 MPa). Owing to its environmental friendliness, low toxicity, and sustainability, the as-prepared GBAF shows the potential to be used in sustainable biopackaging.
