Upcycling of Carbon Fiber/Thermoset Composites into High‐Performance Elastomers and Repurposed Carbon Fibers

Angewandte Chemie International Edition, Journal Year: 2024, Volume and Issue: 63(22)

Published: March 16, 2024

Recycling of carbon fiber-reinforced polymer composites (CFRCs) based on thermosetting plastics is difficult. In the present study, high-performance CFRCs are fabricated through complexation aromatic pinacol-cross-linked polyurethane (PU-AP) thermosets with fiber (CF) cloths. PU-AP exhibit a breaking strength 95.5 MPa and toughness 473.6 MJ m

Upcycling waste commodity polymers into high-performance polyarylate materials with direct utilization of capping agent impurities

Nature Communications, Journal Year: 2025, Volume and Issue: 16(1)

Published: March 12, 2025

Commodity polymers are ubiquitous in our society, having replaced many inorganic and metal-based materials due to their versatile properties. However, functionality heavily relies on the addition of various components known as additives, making it challenging recycle polymer fraction plastic effectively. Thus, is crucial develop efficient chemical recovery strategies for commodity additives facilitate direct utilization recovered monomers without additional purification. Here, we a strategy co-upcycling two types waste polymers, polycarbonate, polyethylene terephthalate into polyarylate, high-performance transparent engineering plastic. By incorporating highly active metal-free ionic liquids catalyst methanolysis two-stage interface polymerization technique with variable temperature control, successfully prepare polyacrylate film from real end-of-life plastics capping agent impurities monomers. These exhibit excellent thermal performance (Tg = 192.8 °C), transmittance (reach up 86.73%), flame-retardant properties (V-0, UL-94), equivalent those commercial polyarylate (U-100, about $10000/ton), could be further easily close-loop recycled. Demonstrated kilogram-scale experiments life cycle assessments, this approach offers low-carbon, environmentally friendly, economically feasible pathway upcycling polymers.

Synthesis of UV-Filtering, Self-Healing, and Self-Adhesion Multifunctional Ionogel for Multimodal Sensation Ionic Skins by Electron Beam Irradiation

ACS Materials Letters, Journal Year: 2025, Volume and Issue: unknown, P. 1250 - 1259

Published: March 4, 2025

As an ion-conductive material, multifunctional ionogels are crucial for the development of i-skin materials. However, current designs face significant challenges in simultaneously achieving mechanical properties, along with self-healing capabilities, multimodal sensing, and high sensory precision. In this work, we propose a strategy situ electron beam irradiation-induced copolymerization highly soluble acrylic acid (AA) poor-solubility 4-allyloxy-2-hydroxybenzophenone (AHBP) to prepare phase-separated ionogels. AHBP not only enables tunable transparency by adjusting degree phase separation but also improves properties ionogel modulating soft/hard domains caused solvent-rich polymer-rich phases. Additionally, efficiently absorbs UV light through conformational changes. Combined its excellent conductivity, thermal stability, outstanding self-adhesive ionogel-based demonstrates sensing capabilities strain, temperature, pressure, showing great potential applications wearable strain sensors multisignal arrays.
