However, such materials are usually in powder form and not convenient to separate from an aqueous media after adsorption, challenges remain in the development of cyclodextrin polymer adsorbents with both efficient adsorption capacity and flexibility. Here, we design a kind of β-cyclodextrin polymer (PCD) functionalized adsorbent via the polymerization of β-cyclodextrin and hexamethyl diisocyanate accompanied by the casting of the mixed solution of polyurethane (PU) and PCD. The flexible adsorbent (PU/PCD) is composed of PU matrix and PCD dispersed phase, which presents remarkable mechanical properties and can be folded 100 times without breaking. Since the surface enrichment of abundant PCD components in the PU/PCD blends could provide numerous accessible adsorption sites, the maximum adsorption capacity of organic pollutant phenolphthalein (PHP) by PU/PCD could reach 235.85 mg/g, which is superior to many other reported adsorbents containing β-CD. Density functional theory (DFT) is employed to understand the interaction mechanism between β-CD and PHP, demonstrating that the supramolecular complex formed is relatively stable. In addition, PU/PCD exhibits good water stability and reusability, and the removal efficiency remains above 96 % even after 5 consecutive cycles of adsorption-desorption. This work thus provides a new insight into the fabrication of PCD surface-functionalized efficient adsorbent with good flexibility and complex affinity for small organic molecules in aqueous media.</div></div>","PeriodicalId":20916,"journal":{"name":"Reactive & Functional Polymers","volume":"211 ","pages":"Article 106194"},"PeriodicalIF":4.5,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143465243","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study evaluated the mechanical, morphological, physical, and biodegradability properties of the NRL composites, both before and after exposure to thermal and gamma aging conditions. Based on the results, the addition of gamma-irradiated MPP significantly enhanced degradation resistance under both thermal and gamma aging. Notably, NRL films containing 9 phr of MPP irradiated at 10 kGy had the highest aging coefficients and the least physical changes for both aging conditions. Additionally, biodegradability assessments on samples that had been buried in soil for 8 weeks indicated that weight loss increased with a higher MPP content and gamma irradiation dose, suggesting a synergistic effect of MPP and gamma irradiation in enhancing the biodegradability of NRL films. Overall, based on the findings, the incorporation of gamma-irradiated MPP not only improved the degradation resistance and biodegradability of the NRL films that sufficiently improved durability of the NR products and reduced industrial waste, but also produced an environmentally-friendly bio-filler that offered a sustainable alternative to conventional, hazardous chemical additives used in the rubber and polymer industries.</div></div>","PeriodicalId":20916,"journal":{"name":"Reactive & Functional Polymers","volume":"210 ","pages":"Article 106198"},"PeriodicalIF":4.5,"publicationDate":"2025-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143455059","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
