Nanofiber membranes via electrospinning with layered structures are frequently used for oil/water separation, thanks to their unique properties. However, challenges that involve nanofibrous still remain, such as high energy consumption and unfavorable transport properties because of the densely compact structure. In this study, superelastic robust nanofiber-based aerogels (NFAs) a three-dimensional (3D) structure well tunable porosity were prepared using polyimide (PI) nanofibers...
An ideal wound dressing for full-thickness regeneration should offer desirable biocompatibility, adequate mechanical properties, barrier function, and cellular regulation. Here, a bilayer scaffold resembling the hierarchical structure of human skin was developed using silk fibroin sodium alginate. The upper membrane prepared through casting functioned as epidermis, whereas lower porous by freeze-drying mimicked extracellular matrix structures. had nonporous structure, moderate hydrophilic...
Bioactive substances such as probiotics are becoming a research hotspot in the field of tissue regeneration due to their excellent regulatory functions. Here, we proposed load Lactobacillus casei onto bilayer silk fibroin/sodium alginate (SF/SA) scaffold endow with both antibacterial and regenerative properties. The performance was characterized systemically. L. casei-loaded scaffolds (L-SF/SA) bring lactic acid, which has wound healing In vitro, cell-free supernatant (CFS) inhibited...
Cocontinuous PLA/EVA (60/40 wt%) blends were filled with reduced graphene oxides (0.1–3 through the master batches of PLA/rGOs and EVA/rGOs, respectively. The results show that rGOs are located at interface when blend nanocomposites prepared from PLA masterbatch. On other hand, in EVA component EVA/rGOs materbatch. underlying mechanism for selective localization was systematically investigated. First, theoretical prediction indicates energies between two polymer components similar prefer to...
Nanofibrous scaffolds were widely studied to construct scaffold for various fields of tissue engineering due their ability mimic a native extracellular matrix (ECM). However, generally, an electrospun nanofiber exhibited two-dimensional (2D) membrane form with densely packed structure, which inhibited the formation bulk in three-dimensional (3D) structure. The appearance yarn (NFY) made it possible further process into desired fabric specific regeneration. Here, poly(l-lactic acid) (PLLA)...
Abstract Engineering skin substitutes represent a prospective source of advanced therapy in repairing severe traumatic wounds. Sodium alginate (SA) and silk fibroin (SF) are natural biomaterials, which widely used tissue engineering other fields because their low price, high safety, good biocompatibility. However, SA itself degrades slowly, its degradation mode is difficult to control, the products remove from body molecular weight. Therefore, composite scaffolds were prepared by...
Graphene oxide (GO) and carbon nanotubes (CNTs) were simultaneously introduced into an immiscible polymer blend. The dispersion of fillers the electrical resistivity composites studied. results first showed that more CNTs trapped at blend interface by GO. Consequently, a remarkable decrease about 7 orders magnitude was achieved even if concentration only 0.1 wt%. Further quaternary exhibited much smaller percolation threshold (0.06 wt%) compared with ternary containing (0.24 wt%).
Owing to the hierarchically three-dimensional (3D) network, ultralow density, and high porosity, nanofiber-based aerogels (NFAs) have drawn great attention recently. However, precise control of porous structure mechanical properties NFAs, which been proved be extremely essential applications, still remains a major challenge. Herein, electrospun polyimide (PI) nanofibers were utilized as building blocks construct NFAs through solid-templating technique. The PI (PI-NFAs) could adjusted by...

When proteins are removed from their native state they suffer two deficiencies: (1) glassy behavior with glass transition temperatures (Tg) well above room temperature and (2) thermal instability. The originates in multiple hydrogen bonds between amino acids on adjacent protein molecules. Proteins, like most biopolymers, thermally unstable. Substituting ovalbumin linear cyclic substituents using a facile nucleophilic addition reaction can affect Tg stability. More hydrophobic lowered by...
