在酸性聚合物存在下，CaCO3的三维浮雕结构是通过在聚合物基质上自发的两步晶体生长而形成的。第一步是薄膜晶体的自组织，其平面显示出周期性变化的结晶学取向。在第二步中，将由针状晶体组成的浮雕结构自发组装在第一步得到的薄膜晶体上。这种方法可能在控制无机/聚合物复合材料的复杂结构方面具有很大的潜力。
Three-dimensional relief structures of CaCO3 are formed by spontaneous two-step crystal growth on a polymer matrix in the presence of an acidic polymer. The first step is self-organization of thin-film crystals with flat surface displaying periodically changing crystallographic orientations. In the second step, the relief structures consisting of needlelike crystals are spontaneously assembled on the thin-film crystals obtained in the first step. This approach may have great potentials to control the complex structures of inorganic/polymer composite materials.
