Abstract
Adhesive constructions include a mammalian skin surface and an adhesive article in contact with the mammalian skin. The adhesive article includes a substrate and an adhesive layer. The adhesive layer in contact with the mammalian skin is a microstructured surface with channels. At least one channel extends to at least one boundary of the adhesive layer. The microstructured surface is a permanently microstructured surface, such that the channels in the surface of the adhesive layer permit transport of fluid.
Claims13
A method of providing fluid transport from an adhesive article attached to mammalian skin comprising:
- providing an adhesive article comprising:
- a substrate with a first major surface and a second major surface;
- an adhesive layer with a first major surface and a second major surface, wherein the second major surface of the adhesive layer is in contact with the first major surface of the substrate, and wherein the first major surface of the adhesive layer comprises a microstructured surface comprising at least one channel that extends to at least one boundary of the adhesive layer, wherein the adhesive layer comprises a pressure sensitive adhesive or a gel adhesive and wherein the microstructured surface comprises a permanently microstructured surface;
- and
- a release liner comprising at least one structured release surface configured to impart the permanently microstructured surface in the adhesive layer;
- removing the release liner from the permanently microstructured surface of the adhesive layer;
- and
- attaching the permanently microstructured surface of the adhesive article to mammalian skin, wherein the channels of the microstructured surface permits the transport of fluid.
