摘要:
A thermo-reversible dry adhesive, having shape memory polymer characteristics, introduces one or more particles of micro- or nano-particles to at least one layer of the at least one layer of shape memory polymer. These particles may be remotely activated to induct heat sufficient to transform the dry adhesive material from its temporary shape to its permanent shape in the absence of load, which allows the dry adhesive to be reversibly coupled to one or more substrates, wherein the degree of adhesion is greater when the dry adhesive is in the temporary shape than in the permanent shape.

A method of reversibly connecting two substrates includes positioning an electrically conductive adhesive connector including a shape memory polymer (SMP) between the substrates, heating the connector to a temperature higher than the SMP transition temperature, applying a load and cooling the connector below the transition temperature to transform the connector to a conforming shape to form an adhesive bond attaching the substrates and providing an electrical connection therebetween. The method may include disconnecting the connector from the substrates by heating the connector above the SMP transition temperature, which may disrupt the electrical connection between the substrates. The connector may be a battery tab connector configured to connect a battery cell to another battery cell or a terminal. The connector may be releasable from the battery tab such that the battery tab is reusable after removal of the connector. The connector may be multi-layer and generally arcuate in a permanent shape.

A device for concealing a seam between a first and second surface includes a seam concealment body having a body surface, the body overlaying and attached to a first surface and a second surface, the body surface being substantially co-planar with a portion of the first and second surfaces, the seam concealment body configured to transition between a first shape and a second shape, wherein the transition permits movement of one or both of the first surface and the second surface such that the seam concealment body forms a hinge. The device also includes an active material in operative communication with the seam concealment body, wherein the active material is configured to undergo a change in at least one property upon receipt of an activation signal, wherein the change in at least one property is effective to transition the seam body from the first shape to the second shape.

摘要:
A fluid includes a liquid medium having iron particles mixed therein. An organic phosphonate based coating is established on the iron particles. The organic phosphonate based coating does not substantially include phosphonic acid groups at an outer surface thereof, and increases oxidation resistance of the iron particles. A method of making such a liquid medium is also disclosed herein.
