Abstract: Electrodes and methods of creating co-continuous composite electrodes based on a highly porous current collector are provided. In one embodiment, a method for creating an electrode includes depositing a thin layer of material on the polymer template, removing polymer material of the polymer template and depositing a second material. The method may also include controlling internal surface area per unit volume and the active material thickness of at least the second material to tune the electrochemical performance of the electrode. In one embodiment, a composite electrode is provided including interpenetrating phases of a metal current collector, electrolytically active phase, and electrolyte.

Abstract: Infusion sets for subcutaneous drug delivery are described herein. The infusion set integrates a bijel-templated material (BTM) into a cannula such that a portion of the BTM protrudes from the cannula tip into the host tissue. The BTM is a porous, polymeric sponge having a co-continuous architecture with consistent curvature throughout non-constricting, interpenetrating channels, which is critical in mitigation of the deleterious host tissue response, vascularization, and flow redistribution in the implant.

Abstract: A method and material composition of a highly porous material that is applied to an object, such as a biomaterial implant and biomedical device, is described. The method involves forming a bijel mixture that is exposed to at least an outer surface of an object. Thereafter, a precursor is added to the bijel mixture to allow the precursor to transport into a particular liquid phase of the bijel mixture. After at least partial transport, the precursor-containing liquid phase of the bijel mixture is solidified to form a bijel-templated material (BTM) that is bonded to a surface of the object.
