    • Certain polymer materials, including perfluorosulfonic acid ionomers, have been found to be capable of being deformed from an initial permanent shape into three or more temporary shapes. An article thus formed from such a polymer material may be used initially in a final temporary shape. As the article is progressively heated, the polymer composition reverts successively from its final temporary shape through its intermediate temporary shapes. If a suitable temperature is reached, the original permanent shape is recovered. The article may be devised to serve successive functions in each of its several shapes.
    • 已经发现某些聚合物材料,包括全氟磺酸离聚物,能够从初始永久形状变形成三种或更多种临时形状。 这样由这种聚合物材料形成的制品可以最初以最终的临时形状使用。 随着制品逐渐加热,聚合物组合物通过其中间临时形状从其最终的临时形状连续地回复。 如果达到合适的温度,则恢复原始的永久形状。 可以设计该物品以在其几种形状中的每一种中提供连续的功能。

    • A shape memory polymer microfiber material coupled to a base portion and coated with a dry adhesive in which the tips of the microfibers may be modified to achieve superhydrophobicity. The resultant surface of the material may be altered between to an adhesive state from a superhydrophobic state as the shape memory polymer transforms from its permanent shape to a temporary shape. The shape memory polymer microfiber material may be reversibly coupled to one or more substrates when in the adhesive state and uncoupled when in the superhydrophobic state.
    • 形状记忆聚合物微纤维材料,其耦合到基部并涂覆有干粘合剂,其中微纤维的末端可以被修饰以实现超疏水性。 当形状记忆聚合物从其永久形状转变成临时形状时,所得材料的表面可以在从超疏水状态到粘合状态之间改变。 当处于粘合状态时,形状记忆聚合物微纤维材料可以可逆地耦合到一个或多个基底,并且当处于超疏水状态时,形状记忆聚合物微纤维材料脱离。
