Eddings and Maohong Fan","doi":"10.1039/D5IM00110B","DOIUrl":"https://doi.org/10.1039/D5IM00110B","url":null,"abstract":"<p>Carbon fibers (CFs) are valuable in applications such as aircraft, automobiles, wind turbines, and energy storage devices. However, the production cost of CFs is high due to the use of conventional precursor polyacrylonitrile, and an affordable substitute is imperative. For the first time, this work combined cheap coal and waste plastic material to fabricate CFs. Currently, conventional disposal methods for waste plastics lack sustainability and profitability. Despite its unpopularity as an energy source, coal can serve as a feedstock for chemicals and materials. High-density polyethylene (HDPE), a commonly used plastic, was hydrogenolyzed into a plastic-derived liquid (PDL). PDL served as an effective solvent during mild solvolysis liquefaction of coal, and the acquired coal–plastic liquid was modified into mesophase coal–plastic liquids (MCPLs). MCPLs were melt-spun and heat-treated into CFs through different heat treatment conditions. The diameters of the CFs were 8.2–45.8 μm, and the Young's modulus and tensile strength were 75–759 GPa and 0.54–4.03 GPa, respectively. The CFs belong to the categories of general-purpose and high-performance CFs. The high-performance CFs (diameter: 8.2 μm, Young's modulus: 759 GPa, and tensile strength: 4.03 GPa) are comparable to commercial and laboratory CFs whose precursors are coal–tar pitch featuring low coal-to-pitch yield, or coal liquefied by conventional, costly solvents. Analysis shows the PDL enhances hydrogen transfer, stabilizes radicals, and promotes mesophase development during thermal treatment. The mechanisms valorizing coal and plastics simultaneously to high-performance CFs are proposed. This work demonstrates a novel and sustainable valorization pathway for waste plastics and coals. Future work will explore industrial-scale plant design, techno-economic analysis, and life-cycle assessment to quantify the economic and environmental impacts.</p><p>Keywords: Environmentally unfriendly polyacrylonitrile; Valorization of waste plastic and coal; Low CO<small>₂</small>-emission; High-performance carbon fiber.</p>","PeriodicalId":29808,"journal":{"name":"Industrial Chemistry & Materials","volume":" 2","pages":" 184-199"},"PeriodicalIF":11.9,"publicationDate":"2025-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2026/im/d5im00110b?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147558282","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We systematically discussed how tailored IEFs construction <em>via</em> heterojunctions, doping, surface modification, and strain engineering can dramatically enhance charge separation, transport, and surface redox kinetics in photoelectrocatalysts. By elucidating the underlying mechanisms (<em>e.g.</em>, band bending, dipole effects, and interfacial screening), we summarized universal principles for IEF manipulation across diverse materials, including metal oxides, chalcogenides, and 2D heterostructures. Furthermore, we critically evaluate performance breakthroughs in solar-to-hydrogen conversion enabled by IEF optimization.

The NPCEs maintain structural integrity after 24 h of continuous shear at 5 °C, with droplet size variation within 20 nm.

Ionic liquids (ILs), with their unique combination of tunable molecular structures, negligible volatility, broad electrochemical windows, and strong solvation capabilities, offer a promising route to address these bottlenecks.

In field-effect transistors and flexible electronics, ILs improve charge transport efficiency, reduce operating voltages, and enhance interfacial stability, while their compatibility with heterogeneous integration addresses reliability challenges in scalable manufacturing.

Building knowledge on prior optimisation of a CO<small>₂</small>–H<small>₂</small> feed, this work extends modelling of SEDMES to a design study for four distinct industrial feeds, with progressively higher CO content. The trade-offs between DME productivity and carbon distribution over the products were studied. The impact of process parameters such as cycle duration, feed flow, operating pressure, temperature, reactant stoichiometry, amount of inert gases and the presence of CO was analysed in detail, including the impact of flexible operation and turndown.
