    • A method for creating or forming a functionally graded 3D ordered open-cellular microstructure, and a functionally graded 3D ordered open-cellular microstructure. In one embodiment, the functionally-graded three-dimensional ordered open-cellular microstructure includes a first three-dimensional interconnected pattern of polymer waveguides having a first three-dimensional pattern; a second three-dimensional interconnected pattern of polymer waveguides having a second three-dimensional pattern differing from the first three-dimensional pattern; and an interface connected with the first three-dimensional interconnected pattern of polymer waveguides and the second three-dimensional interconnected pattern of polymer waveguides. Here, the term “functionally graded” refers to a spatial variation in the physical microstructure—and thus the properties—through the thickness of the material.
    • 一种用于创建或形成功能梯度的3D有序开放细胞微结构的方法,以及功能梯度的3D有序开放细胞微结构。 在一个实施例中,功能梯度的三维有序开孔细胞结构包括具有第一三维图案的聚合物波导的第一三维互连图案; 具有不同于第一三维图案的第二三维图案的聚合物波导的第二三维互连图案; 以及与聚合物波导的第一三维互连图案和聚合物波导的第二三维互连图案连接的界面。 在这里,术语“功能梯度”是指材料的物理微观结构的空间变化,因而是材料的厚度的特性。

    • An ordered ceramic microstructure and a method of making the same. In one embodiment, the ceramic microstructure includes a base structure and one or more ceramic layers. The base structure includes a plurality of first truss elements defined by a plurality of first self-propagating polymer waveguides and extending along a first direction, a plurality of second truss elements defined by a plurality of second self-propagating polymer waveguides and extending along a second direction, and a plurality of third truss elements defined by a plurality of third self-propagating polymer waveguides and extending along a third direction. Here, the first, second, and third truss elements interpenetrate each other at a plurality of nodes to form a continuous material, and the base structure is self-supporting. In addition, the ceramic layers coat a surface of at least one truss element of the first truss elements, the second truss elements, or the third truss elements.
    • 有序的陶瓷微结构及其制造方法。 在一个实施例中,陶瓷微结构包括基底结构和一个或多个陶瓷层。 基底结构包括由多个第一自传播聚合物波导限定并沿着第一方向延伸的多个第一桁架元件,由多个第二自传播聚合物波导限定并沿着第二方向延伸的多个第二桁架元件 方向,以及由多个第三自传播聚合物波导限定并沿着第三方向延伸的多个第三桁架元件。 这里,第一,第二和第三桁架元件在多个节点处相互渗透以形成连续材料,并且基部结构是自支撑的。 此外,陶瓷层涂覆第一桁架元件,第二桁架元件或第三桁架元件的至少一个桁架元件的表面。
