Rapid social and industrial development has resulted in an increasing demand for fossil fuel energy, which increases particulate matter (PM) pollution. In this study, we employed a simple one-step electrospinning technique to fabricate polysulfone (PSF) fiber membranes for PM filtration. A 0.3 g/mL polymer solution with an N,N-dimethylformamide:tetrahydrofuran volume ratio of 3:1 yielded uniform and bead-free PSF fibers with a diameter of approximately 1.17 μm. The PSF fiber membrane exhibited excellent hydrophobicity and mechanical properties, including a tensile strength of 1.14 MPa and an elongation at break of 116.6%. Finally, the PM filtration performance of the PSF fiber membrane was evaluated. The filtration efficiencies of the membrane for PM2.5 and PM1.0 were approximately 99.6% and 99.2%, respectively. The pressure drops were 65.0 and 65.2 Pa, which were significantly lower than those of commercial air filters. Using this technique, PSF fiber membrane filters can be easily fabricated over a large area, which is promising for numerous air filtration systems.

Developing efficient and recyclable membranes for water contaminant removal still remains a challenge in terms of practical applications. Herein, a recyclable membrane constituted of polyacrylonitrile-graphene and oxide-polydopamine was fabricated and demonstrated efficient adsorption capacities with respect to heavy metal ions (62.9 mg g−1 of Cu2+ ion, CuSO4 50 mg L−1) and organic dye molecules (306.7 mg g−1 of methylene blue and 339.6 mg g−1 of eriochrome black T, MB/EBT 50 mg L−1). The polyacrylonitrile fibers provide the skeleton of the membrane, while the graphene oxide and polydopamine endow the membrane with hydrophilicity, which is favorable for the adsorption of pollutants in water. Benefitting from the protonation and deprotonation effects of graphene oxide and polydopamine, the obtained membrane demonstrated promotion of the selective adsorption or desorption of pollutant molecules. This guarantees that the adsorbed pollutant molecules can be desorbed promptly from the membrane through simple pH adjustment, ensuring the reusability of the membrane. After ten adsorption–desorption cycles, the membrane could still maintain a desirable adsorption capacity. In addition, compared with other, similar membranes reported, this composite membrane displays the highest mechanical stability. This work puts forward an alternative strategy for recyclable membrane design and expects to promote the utilization of membrane techniques in practical wastewater treatment.

Heart valve diseases (HVDs) are a major health issue and are significant causes of mortality worldwide. Despite technological developments, current valve substitutes still face major challenges such as thrombogenicity, limited durability, and lack of growth or remodeling capabilities. To handle the limitations of currently used valve prostheses, heart valve tissue engineering (HVTE) has become a viable option for generating biological valve alternatives. However, a major challenge when designing functional HVTE is mimicking the structural and anisotropic mechanical characteristics of the valve leaflets in their natural state. To achieve a biomimetic structure, this study aims to create an anisotropic microenvironment by focusing on the ventricularis layer of the leaflet. Through this approach, we reported the fabrication and characterization of a novel composite nanofibrous radial aligned scaffold consisting of polycaprolactone (PCL), poly(glycerol sebacate) (PGS), and anticoagulant polysulfone (PSf) polymers by combining 3D printing and electrospinning techniques. Radially aligned PCL/PGS/PSf scaffolds enhanced human umbilical vein endothelial cells (HUVECs) cell viability and induced alignment as shown from fluorescence microscopy analysis. Meeting the anisotropy requirements, the composite heart valves of PCL/PGS/PSf nanofibrous scaffolds would be a tissue engineering construct.
