我们对各种结构的遥爪聚合物进行了简要回顾，重点关注结构、溶质溶剂相互作用、聚集过程、平衡和动力学性质以及应用。遥爪是具有官能化、相互吸引的端基的大分子，其呈现多种构象，具体取决于溶剂质量、溶剂的盐度和 pH 值以及特定的大分子结构。在浓缩溶液中，遥爪聚合物为创造具有独特流变特性的新型材料提供了独特的可能性。根据化学和结构，它们可以产生渗透簇和瞬态凝胶，或者可以显示宏观相分离为稀相和结构化致密相。从外部控制这些结构的形态和材料的伴随物理性质的可能性使遥爪聚合物成为现代材料科学的重要且通用的构建模块。
We present a concise review of telechelic polymers of various architectures, focusing on the structure, solute solvent interactions, aggregation processes, equilibrium and dynamical properties and applications. Telechelics are macromolecules with functionalized, mutually attractive end-groups, which assume a variety of conformations that depend on solvent quality, salinity and pH of the solvent, as well as on the particular macromolecular architecture. In concentrated solutions, telechelic polymers offer unique possibilities to create novel materials with distinct rheological properties. Depending on chemistry and architecture, they can create percolating clusters and transient gels or they can show macroscopic phase separation into a dilute and a structured dense phase. The possibility to externally steer the morphology of these structures and the concomitant physical properties of the materials renders telechelic polymers into important and versatile building blocks for modern materials science.
