A sheet material with an anti-skid surface, suitable for use as a roofing underlayment or wrapper, comprises a scrim made of woven plastic tapes with monofilaments that are round in cross-section and have a diameter larger than the thickness of the plastic tapes interwoven with the tapes. The monofilaments form ridges on the sheet material that impart an enhanced coefficient of friction to it. The monofilaments may be incorporated in the weave in the warp or weft directions or both.

The invention relates to lithium-based battery systems and, more particularly, to electro-spinable solution compositions, electro-spun sulfur-polymer fibers, e.g., wires and yarns, and their use in preparing high performance sulfur mattes, e.g., electrodes, for lithium-sulfur batteries with potential applications in small-scale mobile devices. The sulfur-polymer fibers have nanoscale dimensions and yarn-like morphology. The sulfur-polymer fibers can be prepared by co-dissolving sulfur and polymer in a solvent for forming the electro-spinable solution, and electrospinning the solution. The electrospun fibers can be used to form a composite that includes alternating layers of the electrospun fibers and polymer on a current collector.

Provided herein are protective masks made with polymer-based materials and methods of forming the materials. Methods of forming the interlaced polymer-based materials comprise applying adhesive to a substrate, electrospinning a first polymer solution onto the substrate from a first group of spinning electrodes, electrospinning a second polymer solution onto the substrate from a second group of spinning electrodes, and applying hot air to dry the polymer-based materials electrospun from the first polymer solution and the second polymer solution to form the interlaced polymer-based materials.

A method of producing poly (3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) fibers includes the step of extruding a PEDOT:PSS dope through a spinneret into a coagulation bath of a non-solvent to PEDOT:PSS polymer to produce an individual filament that floats to an upper surface of the coagulation bath. The non-solvent to PEDOT:PSS polymer has a boiling point less than 125 C. and a density higher than the PEDOT:PSS nascent filament. The individual filament is dried and then contacted with other dried filaments to make a multifilament tow.

The present invention provides a skin-adhesive air-permeable intelligent bandage comprising: a stretchable adhesive antibacterial bioelectrical interface film made of stretchable adhesive antibacterial fibres; a waterproof moisture-permeable protective film for protecting the wound from external contaminants; and a permeable stretchable circuit assembly arranged between the bioelectrical interface film and the protective film. The permeable stretchable circuit assembly comprises: a permeable stretchable circuit board; one or more biosensors constructed on the permeable stretchable circuit board; and electronic components assembled on the permeable stretchable circuit board. The electronic components include: a physiological signal processing module electrically coupled to the one or more biosensors for in-situ wound monitoring; and a drug delivery actuation module electrically coupled to the bioelectrical interface film for adaptive drug delivery for wound treatment. The provided bandage is more convenient, comfortable and efficient without numerous dressings, thereby not hindering the daily activities and life quality of patients.
