Abstract
A selective adhesive mechanism comprises an engineered surface structure or substrate and a compliant member. The compliant member is able to be a dry and non-tacky substance. The compliant member is selectively adhesive to the engineered surface when the compliant member is in contact with the engineered surface. The compliant member shows adhesion to the engineered surface when the compliant member is within a pre-selected range of hardness. In some embodiments, the compliant member comprises a polymeric member, a thermoplastic elastomer, silicone, polyurethane, or a combination thereof.
Claims26
A reversible adhesive mechanism comprising:
- a) a first member having a spray-coated engineered non-tacky surface, wherein the spray-coated engineered non-tacky surface comprises nanopores formed by imperfect packing of sprayed nanoparticles;
- and
- b) a second member comprising a non-tacky compliant member, wherein the non-tacky compliant member deforms to fill in the nanopores forming a selective adhesivity toward the engineered non-tacky surface when the non-tacky compliant member is in physical contact with the spray-coated engineered non-tacky surface.
A set of reversible adhesive material comprising:
- a) a first surface comprising a non-tacky polymeric material;
- and
- b) a second spray-coated non-tacky surface containing nanopores formed by imperfect packing of sprayed nanoparticles, wherein the second non-tacky surface is selectively adhesive to the non-tacky polymeric material by deforming the non-tacky polymeric material to fill in the nanopores when the second non-tacky surface is in contact with the first surface.
A fastening device comprising a first surface containing a non-tacky polymeric material and a second non-tacky surface containing a spray-coated engineered non-tacky surface, wherein the fastening device is able to fasten an object when the first surface is in physical contact with the second non-tacky surface, wherein the fastening results from selective adhesion due to the non-tacky polymeric material deforming to fill in nanopores on the spray-coated engineered non-tacky surface, wherein the selective adhesion is reversible and the nanopores are formed by imperfect packing of sprayed nanoparticles.
A reversible adhesive mechanism comprising:
- a) a first member having a spray-coated non-tacky engineered surface, wherein the spray-coated non-tacky engineered surface comprises fumed silica or fumed alumina nanoparticles and pores, wherein the pores contain nanopores formed by imperfect packing of sprayed fumed silica nanoparticles or sprayed fumed nanoparticles;
- and
- b) a second member comprising a non-tacky compliant member to be selectively adhered to the spray-coated non-tacky engineered surface by deforming the non-tacky compliant member to fill in the nanopores, wherein the non-tacky compliant member comprises a polymeric material and forms an adhesive bond with the spray-coated non-tacky engineered surface when the non-tacky compliant member and the spray-coated non-tacky engineered surface are brought into physical contact, further wherein the polymeric material comprises polyurethane and is selectively adhered to the spray-coated non-tacky engineered surface when a hardness of the polymeric material is within a preselected range of Shore A scale of a durometer.
