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.

1-26. (canceled)
A selective reversible adhesive material comprising:
- a) a coated engineered surface having pores formed by imperfect packing of particles;
- and
- b) a compliant member comprising a polymer having a hardness in a durometer scale that is 55 Shore A or lower, wherein the compliant member deforms to fill in the pores forming a selective adhesivity toward the coated engineered surface when the compliant member is in physical contact with the coated engineered surface.
An adhesive material comprising:
- a) a liquid coated surface having pores formed by imperfect packing of particles;
- and
- b) a compliant member having a hardness in a durometer scale that is 55 Shore A or lower, wherein the compliant member deforms to fill in the pores forming a selective adhesivity toward the liquid coated surface when the compliant member is in physical contact with the liquid coated surface.
A method of forming a selective reversible adhesive material comprising:
- a) coating a surface forming pores by imperfect packing sprayed particles;
- b) forming a polymeric compliant member having a hardness in a durometer scale that is 55 Shore A or lower;
- and
- c) forming a selective adhesive bonding by deforming the polymeric compliant member to fill in the pores.
