    摘要: The present disclosure is generally directed to hydrogel-fibrous web composites that can be used various heat transfer applications. For instance, the thermally conductive hydrogel-fibrous web composite can be used as a skin-contacting layer in a thermal energy transfer pad used to control patient body temperature. The hydrogel polymer is integral to the fibers of the web. Thus, the hydrogel-fibrous web composite provides good thermal conductivity and skin adhesion properties. The present disclosure is also generally directed to methods of preparing the hydrogel-fibrous web composites.

    摘要: A coated porous substrate composed of a hydrophobic polymer which is substantially uniformly coated with a hydrophilic polymeric material. The substrate may be a sheet-like material, examples of which are foams, fibers, and fibrous webs. The fibrous webs desirably will be nonwoven webs. The coating on the substrate is durable to an aqueous medium at a temperature in a range of from about 10.degree. C. to about 50.degree. C. and does not significantly suppress the surface tension of an aqueous medium with which the coated substrate may come in contact. The hydrophobic polymer may be a polyolefin, such as polyethylene or polypropylene. The hydrophilic polymeric material with which the polymer fibers are coated may be a polysaccharide or a modified polysaccharide. Also provided is a method of preparing a coated porous substrate which involves providing a porous substrate composed of a hydrophobic polymer. At least a portion of the substrate then is exposed to a field of reactive species. At least a portion of the porous substrate, including the portion exposed to the reactive species, is treated with a mixture which includes water and a hydrophilic polymeric material under conditions sufficient to substantially uniformly coat the porous substrate with the hydrophilic polymeric material.

    摘要: Electrically conductive adhesive hydrogels formed from a composition which generally includes a monomer, an initiator, an organic solvent, and a cross-linking agent are suitable for use as skin contact adhesives and, particularly, suitable for use as an electrical interface for disposable medical devices. The present hydrogels provide for reduced skin irritation and/or malodor properties, hydrate a subject's skin, readily wet around a subject's skin surface hair, and protect against burning of a subject upon or due to electrical stimulation through the hydrogel.
