α-磷酸锆(Zr(HPO ₄ ) ₂ ·H ₂O,α-ZrP)是一种无机层状化合物。自1964年首次报道结晶α-ZrP以来，由于其合成简单和独特的理化性质，α-ZrP在机械增强、阻隔改进、阻燃、防腐、催化、环境、能源、和药。由于 α-ZrP 易于剥离以获得单层纳米片，以及由于有序排列的表面酸性羟基的高密度而具有丰富的表面化学性质，α-ZrP 单层纳米片是自-组装或与其他化学品组装。α-ZrP纳米片的组装可以形成随机分散的结构（各向同性），大致有序的结构（向列），或液体胶体或固体混合物（包括水凝胶）中的高度有序结构（近晶）。由于组件的独特结构和新颖功能的结合，组装材料因其优异的性能而得到了广泛的应用。本文综述了α-ZrP的合成方法、剥离α-ZrP的途径和机制、将α-ZrP纳米片组装成各种结构的策略以及组装材料的应用。设想了 α-ZrP 纳米片作为下一代功能应用中的关键材料的新兴前景。组装材料因其优异的性能而得到了广泛的应用。本文综述了α-ZrP的合成方法、剥离α-ZrP的途径和机制、将α-ZrP纳米片组装成各种结构的策略以及组装材料的应用。设想了 α-ZrP 纳米片作为下一代功能应用中的关键材料的新兴前景。组装材料因其优异的性能而得到了广泛的应用。本文综述了α-ZrP的合成方法、剥离α-ZrP的途径和机制、将α-ZrP纳米片组装成各种结构的策略以及组装材料的应用。设想了 α-ZrP 纳米片作为下一代功能应用中的关键材料的新兴前景。

Assembly of exfoliated α-zirconium phosphate nanosheets: Mechanisms and versatile applications

α-Zirconium phosphate (Zr(HPO₄)₂·H₂O, α-ZrP) is an inorganic layered compound. Since the first report of crystalline α-ZrP in 1964, thanks to its simple synthesis and unique physiochemical properties, α-ZrP has found widespread application in many fields including mechanical reinforcing, barrier improvement, flame retardancy, anticorrosion, catalysis, environment, energy, and medicine. Because of the ease of exfoliation of α-ZrP to obtain single-layer nanosheets, as well as its rich surface chemistry thanks to the high density of orderly arranged surface acidic hydroxyl groups, α-ZrP single-layer nanosheets are ideal building blocks for self-assembly or assembly with other chemicals. The assembly of α-ZrP nanosheets could form a randomly dispersed structure (isotropic), roughly ordered structure (nematic), or highly ordered structure (smectic) within liquid colloids or solid hybrids (including hydrogels). Thanks to the combination of the unique structures and the novel functions of the components, the assembled materials have found a wide verity of applications due to their excellent properties. In this article, the methods to synthesize α-ZrP, the approaches and mechanisms to exfoliate α-ZrP, and the strategies to assemble α-ZrP nanosheets to form various structures, as well as the applications of the assembled materials are reviewed. The emerging prospects of α-ZrP nanosheets as a key material in next-generation functional applications are envisioned.
