    • An external covering and method of making an external covering for hiding the internal endoskeleton of a mechanical (e.g., prosthetic) device that exhibits skin-like qualities is provided. The external covering generally comprises an internal bulk layer in contact with the endoskeleton of the prosthetic device and an external skin layer disposed about the internal bulk layer. The external skin layer is comprised of a polymer composite with carbon nanotubes embedded therein. The outer surface of the skin layer has multiple cone-shaped projections that provide the external skin layer with superhydrophobicity. The carbon nanotubes are preferably vertically aligned between the inner surface and outer surface of the external skin layer in order to provide the skin layer with the ability to transmit heat. Superhydrophobic powders may optionally be used as part of the polymer composite or applied as a coating to the surface of the skin layer to enhance superhydrophobicity.
    • 本发明提供了一种用于隐藏表现出皮肤质量的机械(例如,假体)装置的内部骨骼的外部覆盖物的外部覆盖物和方法。 外部覆盖物通常包括与假体装置的内骨骼接触的内部主体层和围绕内部体层设置的外部皮肤层。 外部皮肤层由嵌入有碳纳米管的聚合物复合材料构成。 皮肤层的外表面具有多个锥形突起,其使外部皮肤层具有超疏水性。 优选地,碳纳米管在外表皮层的内表面和外表面之间垂直对准,以便使皮肤层具有传递热量的能力。 可以任选地将超疏水性粉末用作聚合物复合材料的一部分,或作为涂层涂覆到表层的表面以增强超疏水性。
