HIGH-SURFACE AREA ELECTRODES FOR WEARABLE ELECTROCHEMICAL BIOSENSING
20230050906 · 2023-02-16 ·

The present invention is directed to the production of stretchable wrinkled film electrodes for use in wearable/portable ROC systems using electrochemical analysis techniques. A polymer layer is disposed on a conductive substrate and a sacrificial layer is disposed on said polymer layer. An electrode shape template is cut out of adhesive and disposed on the sacrificial layer. A metallic film is disposed on the sacrificial layer by the electrode shape template. The disposed layers are removed from the conductive substrate and placed in an oven to allow said layers to shrink. The shrunken metallic film is treated with a solution to promote bonding between the film and an elastomer. The elastomer is drop-cast onto the shrunken film and the sacrificial layer is dissolved to detach the shrunken polymer layer. The shrunken film and elastomer are placed in a chemical bath and dried, producing the stretchable wrinkled film electrode.

Heat bonding of low energy surface substrates

A method comprising providing a polymeric substrate having a melting point of from about 130° C. to about 190° C., and locating a material layer onto the substrate, wherein the material layer comprises one or more polymeric materials that liquefy upon exposure to temperatures of at least about 100° C., to blend with a softened portion of the polymeric substrate. Upon exposure of one or more of the substrate and the material layer to a stimulus, the temperature is increased in a predetermined temperature zone of one or more of the substrate and material layer to cause blending of the one or more polymeric materials of the material layer with the softened portion of the polymeric substrate.

BONDING OF COMPOSITE MATERIALS
20180001572 · 2018-01-04 · ·

A method for surface preparation of composite substrates prior to adhesive bonding. A curable surface treatment layer is applied onto a curable, resin-based composite substrate, followed by co-curing. After co-curing, the composite substrate is fully cured but the surface treatment layer remains partially cured. The surface treatment layer may be a resin film or a removal peel ply composed of resin-impregnated fabric. After surface preparation, the composite substrate is provided with a chemically-active, bondable surface that can be adhesively bonded to another composite substrate to form a covalently-bonded structure.
