Electrically conducting nano (micro) poly(3,4-ethylenedioxythiophene) (PEDOT) fiber non-woven web was fabricated using the electrospinning technique by applying high voltage of 10 to 30 kV to the electrospinning solution. To investigate the effects of various conditions on formation and properties of PEDOT fiber non-woven web, we changed the solvent or other components and their concentrations. We used 1-propanol or 1-butanol as a solvent and poly(vinyl pyrrolidone) (PVP) as a matrix polymer to prepare the electrospinning solution. The electrical conductivity of the electro-spun PEDOT non-woven web was as high as 7.5 S/cm when 1-propanol was used as the solvent. Electrochemical capacitor was assembled using one pair of the PEDOT non-woven webs as the electrodes by a simple stack method, where metal plates were used as current collectors. We observed the electrochemical charge and discharge behavior of the capacitor, confirming that the PEDOT non-woven web can be used as the electrode for flexible electrochemical capacitor.

Antibacterial properties of engineered materials are important in the transition to a circular economy and societal security, as they are central to many key industrial areas, such as health, food, and water treatment/reclaiming. Nanocoating and electrospinning are two versatile, simple, and low-cost technologies that can be combined into new advanced manufacturing approaches to achieve controlled production of innovative micro- and nano-structured non-woven membranes with antifouling and antibacterial properties. The present study investigates a rational approach to design and manufacture electrospun membranes of polysulfone (PSU) with mechanical properties optimized via combinatorial testing from factorial design of experiments (DOE) and endowed with antimicrobial silver (Ag) nanocoating.

In this study, natural silk web and natural silk non-woven fabric were prepared mechanically using the binding character of the sericin in silk. The effect of process variables on the preparation, structure, and properties of the silk web and the non-woven fabric was examined. The reeling velocity affected the morphology and mechanical properties of the web but had almost no influence on the crystalline structure of the silk.

Face masks are becoming one of the most useful personal protective equipment with the outbreak of the coronavirus (CoV) pandemic. The entire world is experiencing shortage of disposable masks and melt-blown non-woven fabrics, which is the raw material of the mask filter. Recyclability of the discarded mask is also becoming a big challenge for the environment.

Constructing heterostructures can facilitate photoinduced charge separation, leading to enhanced photocatalytic performance. However, spatial separation of charge carriers in traditional type II heterojunctions is at the expense of their redox ability. In this paper, well-designed direct Z-scheme systems (ZSS) of p-CuAlO/n-BiWO composite nanofibers with uniform non-woven web nanostructure was built by electrospinning technique and solvothermal reactions.
