Summary: This research evaluated the potential of bioactive chitosan@poly (ethylene oxide)@CuFe2O4 (CS@PEO@CF) nanofibers in wound healing. The nanoparticles showed antibacterial and antioxidant properties and did not adversely affect fibroblast cell viability. The nanofibrous mats promoted cell migration and growth at the wound edge, leading to enhanced wound healing and regeneration of sebaceous glands and hair follicles within the skin.

Summary: In this study, the shape memory properties of poly(lactic acid) (PLA)/poly(ethylene glycol) (PEG) blends were improved by adding maleic anhydride-grafted poly(lactic acid) (PLA-g-MA) as a compatibilizer. The PLA-g-MA improved interfacial adhesion between phases and promoted chain entanglement, leading to enhanced mechanical properties and shape fixity performance. The compatibilized blend containing 2 wt% PLA-g-MA exhibited the best shape fixity and recovery performance.

Summary: This study investigated the blends of polyethylene oxide (PEO) and poly(sodium 1-[3-(methacryloyloxy)propylsulfonyl]-1-(tri-fluoromethanesulfonyl) imide) (PNaMTFSI) for their application as solid electrolytes in sodium batteries. PNaMTFSI was found to decrease the crystal growth rate of PEO but increase its nucleation rate, leading to higher overall crystallization rate in the blends. The ionic conductivity of the blends was also influenced by the composition, with the highest values observed at 15 and 30 wt% PNaMTFSI.

Summary: This study investigates the thermal transitions, crystallization, and molecular mobility of a series of sustainable polymeric blends based on poly(lactic acid) (PLA) and poly(ethylene adipate) (PEAd). The addition of PEAd to PLA enhances the plasticization of PLA chains and facilitates the nucleation of PLA, leading to strong cold crystallization. The blends also exhibit partially miscible polymers and systematic alternation in both local dynamics and dielectric strength. These PLA/PEAd blends have the potential to be used as phase change materials for tuning material performance.

Summary: This study discusses the irradiation consequences on SIS/PCL blends, focusing on oxidation initiation. Three characterization methods are used: chemiluminescence, differential scanning calorimetry, and FTIR spectroscopy. The inhibition protection of PCL on the faster oxidation of SIS is related to the activation energies and kinetic parameters of degradation during accelerated damaging of blended polymers.

Summary: Vinyl-functionalized graphene oxide (VGO) was used as a reactive compatibilizer in the preparation of PLA/PBAT blends. The results showed that VGO nanosheets were effective in improving the blend's compatibility and PLA crystallinity. The prepared PLA/PBAT pellets were also successfully applied to 3D printing.

Summary: This work investigates the effect of uniaxial stretching on the properties of neat poly(L-lactide) (PLLA) and miscible PLLA/poly(vinyl acetate) (PVAc) blends. The stretching process influences the thermal properties, crystallization behavior, miscibility, crystal structure, and mechanical properties of the materials. With an increased stretching ratio, the chains in PLLA and PLLA/PVAc blends become more oriented and exhibit enhanced crystallization, resulting in changes in thermal properties and improved toughness. The findings provide insight into the effect of stretching on miscible PLLA blends and offer practical implications for their large-scale application.

Summary: Thermally-triggered shape memory polymers (SMPs) can change shape when exposed to heat. Blending PEO and SIS thermoplastic elastomers resulted in a 60PEO/40SIS blend with the best shape memory performance, showing 95.74% shape fixing and 98.98% shape recovery. The presence of semi-crystalline PEO improved shape fixing, while SIS content enhanced shape recovery capability, despite the immiscibility of these polymers.

Summary: The optical and photochromic properties, as well as surface quality, of thin films of methacrylic copolymers containing 2-methylquinoline and quinoline azo-dyes were presented. The presence of a methyl substituent in the 2nd position of the quinoline moiety was found to affect the optical properties and photoisomerization rates of the investigated polymers. The quality of the thin films was examined using Atomic Force Microscopy measurements.

Summary: A new approach was presented for obtaining piezoelectric polymeric films based on isotactic-polypropylene through corona discharge. The study found that surface quality played a crucial role in the possibility of charging the polymeric composites and inducing the piezoelectric effect. High surface smoothness of the polymer films contributed to improved piezoelectric properties without the need for additional polymer modifications.

Summary: The study focused on the production of gelatin/polyvinylpyrrolidone/hydroxyethyl cellulose/glycerol porous matrices with microspheres made of sodium alginate or pectin and sodium alginate. Characterization of the microspheres was done using various techniques, showing that the two-component microspheres were slightly larger than single-ingredient microparticles. The addition of microspheres increased the stiffness and toughness of the prepared materials, but also accelerated the degradation rate of the matrices.
