However, conventional aerogels exhibit isotropic pore structure, limited mechanical robustness, and poor control over multiscale structures, which constrain their broader development and applications. Directional freeze-casting (DFC) has emerged as an efficient strategy to address these challenges by regulating ice crystal growth to form directionally aligned micro/nanostructures. When applied to aerogel fabrication, this technique can impart anisotropic features and significantly enhance overall performance. This review systematically summarizes recent advances in the fabrication of aerogels using various DFC approaches, including unidirectional, bidirectional, radial, and physical field-assisted techniques. It further highlights how these approaches enable precise structural control, performance enhancement, and functional optimization across diverse material platforms, including carbon-, ceramic-, polymer-, MXene-, and metal-based aerogels.

To address these challenges, sustainable polymers have garnered significant attention because they can be recycled, composted, or biodegraded at the end of their life cycle, while also demonstrating reduced environmental impact throughout their lifespan. Self-immolative polymers, degradable polymers, and reprocessable polymers are different types of sustainable polymers that have emerged as particularly promising candidates owing to the presence of reversible and dynamic bonds in their structures. Accordingly, this review begins by exploring polymer recycling methods and then discusses sustainable polymers, with a particular focus on the incorporation of reversible and dynamic chemistry into these materials. Reversible covalent bonds are broken and formed by induction of different stimuli or different states of one stimulus. Dynamic chemistry provides powerful molecular tools for designing constitutionally dynamic materials capable of self-healing, adaptation, reprocessing, and recycling. Dynamic covalent bonds (DCBs) are divided into five groups (pH-, redox-, photo-, thermal-, and mechano-responsive linkages) based on their responsiveness to external stimuli and are discussed in detail. Additionally, this review highlights emerging technologies, such as light-based 3D printing, printable vitrimers, and sustainable foams, rubbers, and adhesives, that incorporate reversible or dynamic covalent chemistries into integrated systems, opening new avenues across diverse scientific fields. Finally, the review addresses current challenges and future opportunities, emphasizing the transformative potential of reversible or dynamic covalent polymers in advancing a more sustainable polymer industry.</div></div>","PeriodicalId":386,"journal":{"name":"Materials Science and Engineering: R: Reports","volume":"168 ","pages":"Article 101174"},"PeriodicalIF":31.6,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145836421","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This pioneering design leverages the terminal functional groups (Tx = F, OH, O) of MXene to enhance metal-substrate interactions, optimize intermediate adsorption, and minimize the chloride ions adsorption, enabling efficient and durable seawater splitting.
