Summary: The enormous potential of electrospun polymer fibers in the field of biomaterials for tissue engineering and wound healing has been explored in this study. Fibrous poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) scaffolds were created to support the anchoring and proliferation of keratinocytes. Hyaluronic acid (HA) was used as a coating on PHBV fibers to improve wound closure processes.

Summary: Poly(3-hydroxybutyrate-co-3-hydroxypentanoate) (PHBV)/graphene oxide (GO) composite membranes were prepared using various solvent mixtures, GO concentrations, and process parameters. The addition of 10 wt% GO nanosheets significantly improved the mechanical properties of the PHBV/GO membrane, resulting in greater breaking strength and tensile modulus. Furthermore, the PHBV/GO membranes exhibited antibacterial properties against E.coli and S.aureus, with a reduction in colonies forming units compared to PHBV membrane, and the development of bacterial biofilm was greatly reduced when incorporating 5-10 wt% GO.

Summary: In order to treat large-scale wounds or chronic ulcers, a poly(3-hydroxybutyrate-co-4-hydroxybuty-rate) (P34HB) fibrous wound dressing that integrates an antibacterial ciprofloxacin (CIP) and pro-angiogenic dimethyloxalylglycine (DMOG) was successfully prepared. The resulting dressing showed excellent biocompatibility, increased cell proliferation, migration, and capillary-like tube formation. The dressings also exhibited broad-spectrum antimicrobial action and promoted wound closure, reepithelialization, collagen formation, angiogenesis, and hair follicle regeneration. This work provides a simple and efficient approach for the design of versatile wound dressings with antibacterial and angiogenic properties.

Summary: This paper evaluates the abrasion resistance of a carbon fiber composite filled with layered-silicate clay nanoparticles. The study investigates the dispersion and performance of the clay-epoxy nanocomposite, and determines the optimal content for fiber composite production. The nanocomposite mixture is prepared by dispersing clay nanoparticles in the epoxy monomer, followed by vacuum infusion to produce the fiber reinforced composite. The presence of nanoclay reduces weight loss and damage on the impacted surface.

Summary: This study fabricated PVA nanofibers reinforced with 1 wt% boron carbide (B4C) using the electrospinning technique. The size and morphology of the B4C particles were found to have a significant impact on the formation and properties of the nanocomposites. The reinforcement of the fibers with sol-gel synthesized nano-sized B4C particles improved the neutron and gamma attenuation of the PVA matrix.

Summary: Research on tissue engineering, particularly heart tissue engineering, is rapidly expanding. Investigated the properties of PCL/PGS and PCL/PGS/graphene nanofibrous scaffolds, finding that blending PGS with PCL enhances elongation and decreases elastic modulus. The addition of PGS reduces hydrophobicity of PCL nanofibers, and graphene balances hydrophilicity. Degradation rate of nanofibers increases in the presence of PGS.

Summary: In this research, bio-based electrospun multilayered films with good barrier properties and superhydrophobic behavior were developed for food packaging applications. Two different biopolymers, a synthetic aliphatic copolyamide and a microbially synthesized poly(3-hydroxybutyrate-co-3-hydroxyvalerate), were processed by electrospinning and layered with organomodified silica nanostructured microparticles. The resulting films exhibited improved barrier and mechanical properties, high water contact angle, and low sliding angle. These biopolymer-based multilayer films could be a promising environmentally friendly alternative for food packaging.
