Systems far-from-equilibrium self-assemble into spatiotemporal structures. Here, we report on the formation of calcium alginate gardens along with their inorganic hybrids when a sodium alginate solution containing sodium phosphate in various compositions is injected into a calcium chloride reservoir. The viscoelastic properties of the membranes developed are controlled by the injection rate, while their thickness by the amount of sodium phosphate besides diffusion. Inorganic hybrid membranes with constant thickness are synthesized in the presence of a sufficient amount of sodium phosphate. The electrochemical characterization of the membranes suggests that the driving force is the pH-gradient developing along the two sides; hence, the cell potential can be controlled by the addition of alkaline sodium phosphate into the sodium alginate solution.
系统远离平衡自组装成时空结构。在这里，我们报告了海藻酸钠花园的形成及其无机杂化体的形成，方法是将含有不同组成的磷酸钠的海藻酸钠溶液注入氯化钙储层中。膜的粘弹性性质由注入速率控制，而其厚度由磷酸钠的量以及扩散共同控制。在有足够量磷酸钠存在的情况下，可以合成具有恒定厚度的无机杂化膜。膜的电化学特性表明，驱动力是沿两侧发展的 pH 梯度；因此，可以通过向海藻酸钠溶液中添加碱性磷酸钠来控制电池电势。
