网络（海绵）和细胞结构常见于各种类型的材料中。具有这种结构的材料一般具有重量轻、机械强度高等特点。例如，骨组织的卓越材料特性凸显了此类材料的有用性，骨组织通常具有高度多孔的结构。在人造材料中，塑料和金属泡沫以及面包都具有这种结构。在这里，我们描述了使用相分离产生网络和细胞结构的物理原理，及其在从软物质到硬物质的材料形态控制中的潜在应用。
Network (sponge) and cellular structures are often seen in various types of materials. Materials with such structures are generally characterized by light weight and high mechanical strength. The usefulness of such materials is highlighted, for example, by the remarkable material properties of bone tissue, which often has a highly porous structure. In artificial materials, plastic and metallic foams and breads have such structures. Here, we describe a physical principle for producing network and cellular structures using phase separation, and its potential applications to the morphological control of materials spanning from soft to hard matter.
