A fiber can include 50 mass % or more of a component A below and 10 mass % or more of a component B below with respect to a mass of a whole fiber. The fiber can include the component A and the component B inside the fiber. The component A is an aliphatic polyester. The component B can be a compound that is an ester compound of a polyhydric alcohol and a fatty acid, can be water-insoluble, can have a solidification point of 30 C. or more, and/or can include a fatty acid group having 14 or more and less than 24 carbon atoms.

Embodiments provide metal batteries (e.g., lithium metal batteries), scaffolded collectors for anodes for such batteries, and methods for making such scaffolded collectors. One formation method includes electrospinning a polymeric material (e.g., polyimide) to form a nanomat, matrix or scaffold with opening or voids therein. The scaffold is treated to incorporate potassium ions which are then replaced by silver ions, which are then converted to silver seeds. The seeded scaffold receives copper via electroplating which is then followed by heat-treating to make the copper smooth and uniform. Openings within the heat-treated copper coated scaffold can then be loaded with anode material (e.g., lithium) and used as part of a metal battery. The copper coated scaffold without additional loading can also be used as current collector in anode-free metal batteries.

Decontaminating materials and methods of making and using the same are provided. The material comprises a network comprising electrospun polymeric nanofibers and at least 50 grams of metal organic framework (MOF) microparticles per m.sup.2 of the network based on the entire area of the network. A composition of the polymeric nanofibers comprises a hydroscopic polymer. An area of the material is defined by an outer surface of the network. The MOF microparticles are retained between the polymeric nanofibers in the network and are configured to decontaminate a chemical threat agent in contact with the material.

At least one face of the nanofiber nonwoven fabric layer (3) is a water-repellent layer (5). The outer fabric layer (2) and the nanofiber nonwoven fabric layer (3) are partially bonded together with an adhesive (4). A method for manufacturing the fabric includes applying a water repellent agent to at least one face of the nanofiber nonwoven fabric layer (3) and curing the water repellent agent to form a water repellent layer (5), and partially bonding the nanofiber nonwoven fabric layer (3) and the outer fabric layer (2) together with an adhesive (4). As a result, the moisture-permeable waterproof laminated fabric that can continue to display the air permeability and the moisture permeability of its moisture permeable film irrespective of exposure to rain and perspiration during wearing, the method for manufacturing the fabric, and a garment including the fabric are provided.

A composite multi-layer textile, comprising at least one nanofibre layer with nanofibres with diameters below 100 nm and one support layer with microfibres with diameters below three microns, wherein the layers were produced by electrospinning. The multi-layer textile shows a general transmittance at #=550 nm greater than 60%, which shows improved properties concerning transparency, breathability and robustness. This is achieved in that the at least one nanofibre layer and the support layer are fused, forming solid domains in the multi-layer textile, at closed areas of a pattern used in the production process, wherein the solid domains are separated from each other or connected, showing defined shapes, with regular or irregular spatial distribution, while the fibre morphology of nanofibres of the nanofibre layer and microfibres of support layer is preserved on top of the open areas beside the solid domains, attaining a general transmittance greater than that given by the sum of the individual layers.
