Abstract: This disclosure provides a portable hemostatic bandage system, which comprises two formulations comprising siloxanes and blowing gas generating agents as well as a dual container device, optionally a dual syringe applicator, for in situ construction of a sponge-like polymer foam as hemostatic bandage material. Two formulations kept separately in a dual container device react instantly with each other when forced to mix, and as a result, decomposition of hydrogen peroxide occurs to generate a blowing gas O2 and heat, and consequently siloxane polymer curing occurs to form polymer foam inside the dual container device. When the blowing foam is applied to a bleeding wound, it forms a sponge plug within a few minutes to control hemorrhage. This portable hemostatic bandage system can be easily used at ambient temperatures, and it is a cost-effective method to control hemorrhage.

Abstract: Disclosed is a coating composition that includes at least one silane or functionalized silane, and at least one electroactive or electroconductive polymer, and optionally a solvent. In particular, the coating composition comprises a mixture of octadecyltrichlorosilane and poly(3,4-ethylenedioxythiophene):polystyrene sulfonate.

Abstract: This invention relates to a biodegradable hydrophobic or omniphobic coating with tailorable properties for various applications. The technology's hydrophobic modifications, surface functionalization, and surface roughness modifications enable low contact angle hysteresis for easy roll-off and self-cleaning properties. The composite is based on polymer substrate(s) or functionalized polymer substrate(s), filler(s), inorganic(s), binder(s), Lycopodium, or a combination of materials. The Lycopodium may be functionalized with suitable end groups for better adhesion or to impart beneficial properties. The polymer(s) and other constituents may be deposited on the substrate by various methods including spin coating, dip coating, spray coating, sputter coating, electrospinning, solvent casting, or extrusion. Binders and chemicals are incorporated in suitable chronology with or without the solvents of choice.
