Polymeric coatings are traditionally utilized to reduce the attachment of foulants on a surface, however low density and thickness of polymer brushes formed by surface initiated polymerization methods, surface exhaustion by continuous exposure to the foulants, and mechanical vulnerability in harsh environments, limit the antifouling performance of these traditional coatings. Recent trends in bioinspired polymeric coatings combine antifouling properties of super-hydrophobic, and highly hydrated lubricating polymers with mechanical properties of micro- and nano-particles to yield contact active, foulant releasable and stimuli responsive materials with superior antifouling performance. This review specifically highlights the development of next generation bioactive antifouling coatings using nature as an inspiration and a discussion of their benefits, over traditional polymeric coatings. The bioinspired coatings obtained are further evaluated for their potential applications in the marine environment, as delivery carriers, in implants, biosensors, and in urinary catheters.","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":" ","pages":"e2400932"},"PeriodicalIF":4.2,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143603182","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, boehmite nanowires (BhNs) with an aspect ratio up to 60 for the modification of transparent polyimide (CPI) derived from the polymerization of fluorodiamine and fluorodianhydride, are prepared. Due to the unique size and orientation distribution of BhNs in CPI films, the as prepared CPI-BhN composite films show in-plane thermal conductivity up to 5.89 W m-1 K-1, which is almost an order of magnitude higher than that of pure CPI (0.626 W m-1 K-1). Meantime, optimal CPI-BhN composite films show a light transmittance of 52.9% at 550 nm and a haze of 35.3%. In addition, the BhNs form a strong hydrogen bond with the CPI polymer chains, enhancing the mechanical properties of the composite films. Studies on thermal stability, fatigue resistance, and flame retardancy indicate that the CPI-BhN composite films have excellent performances. These findings provide a new idea for the design and fabrication of high-performance composite films for new-generation optoelectronic devices.","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":" ","pages":"e2401040"},"PeriodicalIF":4.2,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143603269","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This issue can be effectively overcome through a pre-melt-stretching process, known as mechanical rejuvenation. However, the underlying mechanisms remain poorly understood due to the intricate multilevel structures in pre-stretched PLA and their evolution during physical aging. Herein, PLA containing 12% D-isomer units is utilized as a model system to eliminate the influence of structures such as mesophase and crystals. The samples remain fully amorphous throughout the pre-stretching and subsequent aging processes. Notably, during physical aging, the pre-stretched samples retain their ductility, while the isotropic samples exhibit increased embrittlement. Thermal analysis is employed to elucidate the changes in the amorphous phase during aging. The results reveal the impact of the amorphous segmental mobility on the ductility change during aging, which is primarily governed by the fraction of mobile amorphous phase (XMAF), with a critical threshold determining the ductile-to-brittle transition. This work would shed light on the toughening of physically aged glassy polymers.","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":" ","pages":"e2401126"},"PeriodicalIF":4.2,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143522259","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While chemical doping enhances the carrier concentration in polymer semiconductors, the dopant molecules also function as extraneous impurities, which hinder the aggregation ordering and crystallization of the polymer chains. Thus, the dopant level and the aggregation ordering should be compromised especially for organic field effect transistors (OFET) application. In this work, the processing-structure-performance relationships in poly(3-hexylthiophene) (P3HT) doped with low levels of 2,3,5,6-tetrafluoro-7,7,8,8-tetracyanoquinodimethane (F4TCNQ) is investigated. A microfluidic and ultrasonic field-assisted solution processing strategy (FU) is employed to enhance the chain conformation order in the solution. By virtue of the UV-vis absorption, X-ray scattering, and X-ray absorption spectroscopy, the FU-processed P3HT solution with 1 wt.% doping level demonstrated the highest conformation order in terms of large chain conjugation length and optimal aggregate packing, which further dictating the highest mobility of the corresponding F4TCNQ-doped P3HT film. The chain conjugation length is found to correlate more directly with OFET performance than the macroscopic crystallinity of the film and thus is proposed to be more intrinsic for understanding the electronic transport physics of conjugated polymers.","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":" ","pages":"e2401069"},"PeriodicalIF":4.2,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143522327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, current PTC materials are often constrained in the thermal regulation within the low-temperature range due to the high Curie temperatures. Achieving low Curie temperatures often requires small-molecule polymer matrices, which can compromise mechanical properties and lead to phase change material leakage. To overcome this challenge, this study innovatively proposes a generalized design strategy for bi-continuous phase thermally controlled PTC composite materials (PTCCM) based on polyimide aerogel (PIA) encapsulation. PIA forms a continuous backbone structure, while 1-Tetradecanol serves as a fibrous phase change matrix. Additionally, multi-doped conductive fillers construct an efficient fiber bundle-like network. In the temperature range of 10-50 °C, the PTC strength achieves 3.55, with a low resistivity of 1.5 Ω m. Thanks to its stable PIA skeleton and perfect conductive network, PTCCM can accurately stabilize the device temperature at 29.5 ± 1.5 °C under different low-temperature environments and voltages. The temperature control accuracy is as high as 0.03 °C, presenting excellent cycling stability. These characteristics make it promising in meeting stringent thermal management demands.","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":" ","pages":"e2401064"},"PeriodicalIF":4.2,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143522317","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this challenge, an agent system that integrates large language models (LLMs) and knowledge graphs is proposed. By leveraging LLMs' powerful capabilities for extracting and recognizing chemical substance names, and storing the extracted data in a structured knowledge graph, the system fully automates the retrieval of relevant literature, extraction of reaction data, database querying, construction of retrosynthetic pathway trees, further expansion through the retrieval of additional literature and recommendation of optimal reaction pathways. By considering the complex interdependencies among chemical reactants, a novel Multi-branched Reaction Pathway Search Algorithm (MBRPS) is proposed to help identify all valid multi-branched reaction pathways, which arise when a single product decomposes into multiple reaction intermediates. In contrast, previous studies are limited to cases where a product decomposes into at most one reaction intermediate. This work represents the first attempt to develop a fully automated retrosynthesis planning agent tailored specially for macromolecules powered by LLMs. Applied to polyimide synthesis, the new approach constructs a retrosynthetic pathway tree with hundreds of pathways and recommends optimized routes, including both known and novel pathways.","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":" ","pages":"e2500065"},"PeriodicalIF":4.2,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143522321","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
