Here, we report the preparation of dynamically disulfide (S-S) cross-linked polycaprolactone grafted CO<sub>2</sub>-based poly(ester-co-carbonate) through a combinatorial way. This polymer is characterized by a degradable poly(ester-co-carbonate) as backbone, polycaprolactone (PCL) side chains, and dynamic S-S linkages formed by ring-opening polymerization (ROP) of cyclic disulfide groups induced by heating as cross-linking junctions. A series of cross-linked graft copolymers with varied lengths of semicrystalline and flexible PCL side chains were synthesized. These copolymers crystallized effectively, with mechanical strength and extensibility varying with the side chain lengths. Crystallization, synergistically with dynamic S-S cross-links improved mechanical strength, compared to molten or non-cross-linked systems. The S-S cross-linked network was introduced through thermoplastic processing, endowing polymers with reversible network transitions. Specifically, dynamic dissociation of S-S can occur through thiol-disulfide exchange guaranteeing the cross-linked polymers with reversible de-crosslinking properties. Furthermore, these de-crosslinkable and recyclable polymers could undergo transition from sol to gel state, based on thiol-disulfide exchange facilitating the generation of new S-S intermolecular cross-links. Notably, these cross-linked graft copolymers could undergo efficient base-catalyzed alcoholysis-induced degradation forming oligomers (590 g/mol) due to the presence of abundant aliphatic ester or carbonate ester groups. This strategy offered an effective method to obtain cross-linked graft copolymers with thermal processability, crystallization, mechanical performance, reversible de-crosslinking, and degradability. These desirable properties indicate the promising application prospects of the cross-linked graft copolymers prepared in recyclable and degradable flexible devices, degradable thermoforming packaging, flexible degradable drug controlled-release membranes and highly deformable degradable soft robots, etc.</div></div>","PeriodicalId":315,"journal":{"name":"European Polymer Journal","volume":"234 ","pages":"Article 114026"},"PeriodicalIF":5.8,"publicationDate":"2025-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144147974","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A thorough investigation of the various experimental parameters influencing the brush growth, initially performed under limited air conditions, finally enabled successful SI-photoATRP under fully open-air conditions, without using any additional chemicals for oxygen consumption. The method can operate efficiently at low catalyst concentrations (10–400 ppm) under ambient conditions using simple custom-made polymerization setups. Temporal control can be achieved under open-air conditions, while continuous polymerization is possible in complete darkness after brief UV exposure under limited air conditions. This approach offers potential economic benefits by significantly reducing energy consumption. The reusability of the reaction mixture for up to at least 6 cycles was demonstrated.

To overcome this limitation, a novel dual-wavelength photo-initiating system (2959-EDB/CQ) was developed in this study. 2959-EDB initiator incorporates an α-hydroxy ketone moiety at one end and a tertiary amine group at the other, enabling sequential activation under 465 nm (via camphor quinone-mediated hydrogen abstraction) and 275 nm (C–C α-bond cleavage) irradiation to produce distinct radical species for the controlled polymerization of different monomers. In contrast to conventional bisacylphosphane oxide (BAPO)-based systems, which are prone to photolytic interference, the proposed system allows for the efficient synthesis of well-defined diblock copolymers. Notably, the residual α-hydroxy ketone groups on the initially polymerized surface can be reactivated to initiate UV-induced graft polymerization, as demonstrated by attenuated total reflection infrared spectroscopy, morphological analysis, and contact angle measurements. 2959-EDB/CQ system combines high radical reactivity with procedural simplicity, overcoming the cost-related drawbacks of RAFT-based strategies for diblock copolymers synthesis while retaining the industrial practicality of conventional photopolymerization.

These materials are capable of binding glucose molecules with high specificity, facilitated by their tailored functional groups and advanced design. Optical chemosensors provide several advantages over traditional electrochemical sensors, such as immunity to electromagnetic interference, label-free detection, and potential for remote sensing. Furthermore, they offer enhanced reproducibility and internal calibration, making them suitable for continuous and non-invasive glucose monitoring.
