With that in mind, editing the polymer backbone composition offers exciting opportunities to transform the plastics economy; yet, few examples of such transformations utilize commodity plastics as starting materials. In this work, we describe the development of a tandem C–H oxidation/hydroxyalkyl azide mediated rearrangement strategy that converts polyethylene into “polyethylene-like” materials with iminium ethers, esters, amides, and other pendant chemical functionality. Control over formation of esters or amides is achieved by variation of the hydroxyalkyl azide reagent, as well as processing conditions. By targeting specific functionalities, a variety of thermal and mechanical properties can be accessed. For example, incorporation of iminium ethers decreases the Young’s modulus of post-consumer PE from 196 MPa to 69–83 MPa, but conversion of the iminium ethers to esters and amides produces materials with moduli of 212–287 MPa—values higher than the original material. Thus, the demonstration of a modular backbone editing methodology for polyethylene showcases the broader value of this emerging strategy for polymer modification.","PeriodicalId":100,"journal":{"name":"Polymer Chemistry","volume":null,"pages":null},"PeriodicalIF":4.6,"publicationDate":"2024-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142452353","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}

Due to the restriction of the crosslinking network, traditional thermosetting polymer materials exhibit insolubility and immiscibility. Therefore, reprocessing of thermosetting polymer materials is a great challenge. With the depletion of petroleum-based resources, the utilization of natural resources for the preparation of bio-based thermosetting polymer materials is a major trend. In this study, eugenol-based covalent adaptable thermosets were prepared by UV curing and thermal curing according to thiol click chemistry. The mechanical properties of the eugenol-based covalent adaptable thermosets could be regulated according to the components, which were better than those of the control sample. The eugenol-based covalent adaptable thermosets exhibited excellent transparency and UV shielding properties. The introduction of dynamic covalent boronic ester (BSH) promoted the formation of residual char and enhanced the fire safety of eugenol-based covalent adaptable thermosets. Because of the dynamic borate ester bonds in the cross-linked network, the eugenol-based covalent adaptable thermosets exhibited significant stress relaxation behavior, excellent shape memory function and self-healing properties. The samples could be reprocessed at 100 °C several times. After three cycles of pulverizing and hot pressing, the recovery ratio of the tensile strength for the reprocessed samples remained above 85%. This study provides a novel strategy for preparing self-healable, reprocessable and anti-flammable covalent adaptable thermosets with tunable mechanical properties.","PeriodicalId":100,"journal":{"name":"Polymer Chemistry","volume":null,"pages":null},"PeriodicalIF":4.6,"publicationDate":"2024-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142443937","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}

However, the limited brightness of EUV light source, the distinct exposure mechanism, and the high resolution required for patterns pose significant challenges for resist materials—particularly for conventional polymeric resists, which often suffer from low EUV absorption, high molecular weight, and nonhomogeneous composition. In this Review, we focus on polymer resists for EUV lithography and offer our perspectives on recent exciting advances in the polymer chemistry of these resists. For example, in recent years, there has been significant progress in incorporating high EUV-absorbing moieties and photosensitizers into resists to enhance EUV absorbance and quantum efficiency. Additionally, advancements have been made in developing single-component chemically amplified resists (CARs) with covalently attached photoacid generators (PAGs), as well as in main-chain scission-type resists. Furthermore, the creation of precision oligomeric resists with precisely defined primary sequences and discrete molecular weights has opened new possibilities for EUV resist design. Lastly, we provide a critical outlook on the future opportunities and challenges in the development of EUV resists.","PeriodicalId":100,"journal":{"name":"Polymer Chemistry","volume":null,"pages":null},"PeriodicalIF":4.6,"publicationDate":"2024-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142436336","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}

Herein, to minimize CSPMN potential cytotoxicity, aqueous reversible addition-fragmentation chain transfer polymerization is employed for their synthesis. Initially, “arm-first” star polymers were synthesized in water using poly[oligo(ethylene glycol) methyl ether methacrylate] (POEGMA) homopolymer and, non-degradable ethylene glycol dimethacrylate or acid-labile diacetal-based bis[(2-methacryloyloxy)ethoxymethyl] ether cross-linker. Subsequently, OEGMA addition resulted in preparation of “in-out” star polymers (with higher molecular weights) followed by cross-linker addition to form CSPMNs. Rhodamine B dye encapsulation was performed during CSPMN synthesis and its release was observed in biologically relevant conditions. Having shown the effective breakdown of the diacetal-based CSPMNs, their potential for use in drug delivery in low pH environments (i.e. cancerous tumors) is expected to be high.","PeriodicalId":100,"journal":{"name":"Polymer Chemistry","volume":null,"pages":null},"PeriodicalIF":4.6,"publicationDate":"2024-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142431620","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}

Traditionally, antifouling coatings are covalently bonded to substrates, a process that can be time-consuming or substrate-dependent. In this study, we synthesized both block and random copolymers using poly(ethylene glycol) methyl ether methacrylate (PEGMA) and methacryloxyethyltrimethyl ammonium chloride (METAC) through reversible addition-fragmentation chain transfer (RAFT) polymerization. These copolymers can be adsorbed onto metal-phenolic network (MPN)-modified substrates based on cation-π interactions, rapidly forming antifouling coatings in about 6 min. Due to the wide surface modification ability of MPN, the antifouling coatings could form on various substrates. The antifouling coatings can effectively resist against the adhesion of protein, cell, and bacterial. Moreover, block copolymers exhibited superior antifouling abilities compared to random copolymers. Notably, the antifouling performance of copolymers can be promoted by increasing the amount of PEGMA and METAC. The advantage of the reported method is rapid preparation of antifouling coatings on various substrates. In addition, the study provides an insight into the factors influencing the strength of cation-π interaction.","PeriodicalId":100,"journal":{"name":"Polymer Chemistry","volume":null,"pages":null},"PeriodicalIF":4.6,"publicationDate":"2024-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142431621","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 novel trinuclear cyclohexane-bridged tetradentate Schiff base chromium complex 1 was synthesized as a catalyst for the ring-opening copolymerization (ROCOP) of CO2 and cyclohexene oxide (CHO), resulting in the formation of poly (cyclohexene carbonate) (PCHC). The impact of polymerization temperature, CO2 pressure, reaction time, and catalyst loading on complex 1's polymerization activity was systematically investigated. It was observed that, with the addition of the co-catalyst PPNN3 (PPN= bis(triphenylphosphine)iminium), complex 1 exhibited enhanced catalytic activity for the ROCOP of CO2 and CHO under mild conditions. In contrast, the mononuclear tetradentate Schiff base chromium complex 2 system showed low activity under the same conditions. Compared to complex 2, complex 1 achieved a higher CHO conversion rate (70%) and 85% PCHC selectivity, with a turnover frequency (TOF) of 419 h-1, which is 5.3 times greater than that of complex 2. Additionally, the polymer produced by complex 1 had a molecular weight of 13790 g/mol, which is higher than that produced by complex 2 (8800 g/mol) and the commercial Salen CrCl catalyst (9610 g/mol). By varying the amounts of complex 1 and CHO, PCHC with different molecular weights (6000 g/mol to 14000 g/mol) and low dispersity can be easily obtained. Notably, the activation energy barrier for polycarbonate formation in the complex 1 system was 21.63 kJ/mol, compared to 32.88 kJ/mol in the complex 2 system.","PeriodicalId":100,"journal":{"name":"Polymer Chemistry","volume":null,"pages":null},"PeriodicalIF":4.6,"publicationDate":"2024-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142431623","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}

Incorporating various boron-containing dyes into porous organic polymers effectively addresses the issue of small boron-containing molecules, which are difficult to separate and prone to photobleaching. Nevertheless, the integration of boron-containing dyes into vinylene-linked conjugated porous organic polymers (POPs) remains unexplored. This study reports the synthesis of two distinct vinylene-linked fully conjugated POPs by reacting difluoroboron β-diketonate complexes with reactive methyl groups and a carbazole-bearing aldehyde. The formation of effective D–A interaction between the difluoroboron complexes and the carbazole subunit enhances charge transport and separation, thereby improving photocatalytic efficiency. CTBA-B2, with a higher content of the difluoroboron complex, exhibits superior catalytic activity in both oxidation and reduction reactions, and is capable of efficiently catalyzing sulfide oxidations as well as dehalogenation reactions in green ethanol solvents.","PeriodicalId":100,"journal":{"name":"Polymer Chemistry","volume":null,"pages":null},"PeriodicalIF":4.6,"publicationDate":"2024-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142405328","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}
