    • This disclosure relates to a method for making a polymeric article mold, a method for making a polymeric article with that mold, and improved surface topography features for a polymeric article. A prototype article is formed and then coated with a thin conductive layer. The coated prototype article is then electroformed until nickel plated to a sufficient depth to define a nickel plating tool. After the prototype article has been removed from the mold face of the nickel tool, the tool can be used as a mold for forming finished polymeric articles which replicate the original prototype article. The use of fine topography features such as a dense upstanding stem array on the surface of the prototype article facilitates accurate and complete electroforming by increased surface area presentation. The disclosure also presents improvements to microreplicated surface structures such as stem arrays. The improvements include the formation on a stem array having separate zones of stems of differing heights, and the formation of directional microreplicated features (e.g., stems) which are oriented and shaped to promote or restrict frictional interaction in one or more particular directions.
    • 本公开涉及制备聚合物制品模具的方法,制备具有该模具的聚合物制品的方法以及用于聚合物制品的改进的表面形貌特征。 形成原型制品,然后涂覆有薄导电层。 然后将涂覆的原型制品电铸成直到镀镍至足够的深度以限定镀镍工具。 原型制品已经从镍工具的模具表面上移除后,该工具可以用作复制原始原型制品的成品聚合物制品的模具。 使用精细的地形特征,例如原型制品表面上密集的直立杆阵列,可以通过增加表面积来实现精确和完整的电铸。 本公开还提出了微复制表面结构如茎阵列的改进。 改进包括在具有不同高度的茎的不同区域的茎阵列上的形成,以及定向微复制特征(例如茎)的形成,其定向和成形以促进或限制在一个或多个特定方向上的摩擦相互作用。

    • A heat exchanger utilizing active fluid transport of a heat transfer fluid has multiple discrete flow passages provided by a simple but versatile construction. The microstructured channels are replicated onto a film layer which is utilized in the fluid transfer heat exchanger. The surface structure defines the flow channels which are generally uninterrupted and highly ordered. These flow channels can take the form of linear, branching or dendritic type structures. A cover layer having favorably thermal conductive properties is provided on the structured bearing film surface. Such structured bearing film surfaces and the cover layer are thus used to define microstructure flow passages. The use of a film layer having a microstructured surface facilitates the ability to highly distribute a potential across the assembly of passages to promote active transport of a heat transfer fluid. The thermally conductive cover layer then effects heat transfer to an object, gas, or liquid in proximity with the heat exchanger.
    • 利用传热流体的主动流体输送的热交换器具有由简单而通用的结构提供的多个离散的流动通道。 微结构通道被复制到用于流体传递热交换器中的膜层上。 表面结构定义了通常不间断和高度排序的流动通道。 这些流动通道可以采用线性,支化或树枝状结构的形式。 在结构化轴承膜表面上提供具有良好导热性能的覆盖层。 因此,这种结构化轴承膜表面和覆盖层用于限定微结构流动通道。 使用具有微结构化表面的膜层有助于跨过通道组件高度分布电势以促进传热流体的主动输送的能力。 然后,导热覆盖层对热交换器附近的物体,气体或液体进行热传递。
