Abstract

In this work, we report a versatile strategy enabling simultaneous regulation of both morphology and pore-surface chemistry in mesoporous materials. By introducing diols as ‘noncovalent cross-linking agents’, microphase separation of polystyrene-b-poly(4-vinylpyridine)-b-polylactide triblock terpolymers can be tuned, inducing the formation of a metastable phase with disordered bicontinuous morphology. After selective etching to remove the polylactide end-block, mesoporous structures are obtained with poly(4-vinylpyridine) midblocks retained on the inner pore walls. We demonstrate that the resulting mesoporous materials exhibit efficient adsorption performance for both organic dyes and metal ions, leveraging the functional P4VP segments and interconnected bicontinuous channels. This work offers a facile approach to fabricating functionalized mesoporous materials and provides new mechanistic insights into the design of nanostructured materials with tailored morphology and surface chemistry.

通过动力学方法有效地获得具有双连续形态的功能化介孔材料

在这项工作中，我们报告了一种多功能策略，可以同时调节介孔材料的形态和孔表面化学。通过引入二醇作为“非共价交联剂”，聚苯乙烯-b-聚（4-乙烯基吡啶）-b-聚丙交酯三嵌段三聚体的微相分离可以调整，诱导形成具有无序双连续形态的亚稳相。在选择性蚀刻去除聚丙交酯端块后，获得了具有聚（4-乙烯基吡啶）中间块的介孔结构。我们证明了所得到的介孔材料对有机染料和金属离子都具有有效的吸附性能，利用了功能的P4VP片段和相互连接的双连续通道。这项工作为制造功能化介孔材料提供了一种简便的方法，并为设计具有定制形态和表面化学的纳米结构材料提供了新的机理见解。

期刊介绍： Macromolecules publishes original, fundamental, and impactful research on all aspects of polymer science. Topics of interest include synthesis (e.g., controlled polymerizations, polymerization catalysis, post polymerization modification, new monomer structures and polymer architectures, and polymerization mechanisms/kinetics analysis); phase behavior, thermodynamics, dynamic, and ordering/disordering phenomena (e.g., self-assembly, gelation, crystallization, solution/melt/solid-state characteristics); structure and properties (e.g., mechanical and rheological properties, surface/interfacial characteristics, electronic and transport properties); new state of the art characterization (e.g., spectroscopy, scattering, microscopy, rheology), simulation (e.g., Monte Carlo, molecular dynamics, multi-scale/coarse-grained modeling), and theoretical methods. Renewable/sustainable polymers, polymer networks, responsive polymers, electro-, magneto- and opto-active macromolecules, inorganic polymers, charge-transporting polymers (ion-containing, semiconducting, and conducting), nanostructured polymers, and polymer composites are also of interest. Typical papers published in Macromolecules showcase important and innovative concepts, experimental methods/observations, and theoretical/computational approaches that demonstrate a fundamental advance in the understanding of polymers.
