Abstract
Methods of forming dry adhesives including a method of making a dry adhesive including applying a liquid polymer to the second end of the stem, molding the liquid polymer on the stem in a mold, wherein the mold includes a recess having a cross-sectional area that is less than a cross-sectional area of the second end of the stem, curing the liquid polymer in the mold to form a tip at the second end of the stem, wherein the tip includes a second layer stem; corresponding to the recess in the mold, and removing the tip from the mold after the liquid polymer cures.
Claims12
A method of forming a dry adhesive with a structure including a backing layer and a stem, wherein the stem includes a first end and a second end on opposite sides of the stem, and wherein the first end of the stem is connected to the backing layer, comprising:
- applying a liquid polymer to the second end of the stem;
- after applying the liquid polymer, forming the liquid polymer by contacting the liquid polymer with a tip shaping surface;
- and
- after forming the liquid polymer, curing the liquid polymer on the second end of the stem.
A method of forming a dry adhesive with a structure including a backing layer and a stem, wherein the stem includes a first end and a second end on opposite sides of the stem, and wherein the first end of the stem is connected to the backing layer, comprising:
- applying a liquid polymer to a first surface;
- after applying a liquid polymer to the first surface, contacting the second end of the stem to the first surface to coat the second end of the stem with the liquid polymer;
- withdrawing the second end of the stem from the first surface;
- contacting the liquid polymer on the second end of the stem to a second surface to form a tip;
- and
- after contacting the liquid polymer to a second surface, curing the liquid polymer on the second end of the stem.
