The incorporation of supramolecular interactions as sacrificial bonds for energy dissipation is an effective strategy to enhance the mechanical performance of polymers. However, this approach can result in a loss of resilience due to excessive energy consumption. In this study, we developed a kind of noncovalently supramolecular and covalently dual-cross-linked fluorinated acrylic polyurethane (PU-PFOMA) by incorporating adipic acid dihydrazide and acrylate-modified cyclodextrins into the polyurethane main chains and polymerizing perfluorooctyl methacrylate (PFOMA) in the polyacrylate side chains. The resulting PU-PFOMA demonstrated superior mechanical properties (54.36 MPa), elongation at break (1150%), and toughness (248.05 MJ/m³) due to the multiple H-bonds formed by adipic acid dihydrazide and the stable covalently cross-linked structure achieved through radical copolymerization. Furthermore, PU-PFOMA exhibited excellent resilience, attributed to the stable interchain cross-linking and the driving force generated by the poly(oxytetramethylene) glycol (PTMG) and PFOMA segments to reform their respective aggregates, owing to their thermodynamically incompatible nature. PU-PFOMA also demonstrated exceptional low-temperature resistance, including high strength (265.62 MPa), high toughness (648.44 MJ/m³) at −70 °C, and excellent resilience at −60 °C. More importantly, the PU-PFOMA elastomer has good solvent resistance that compared with PU because of the introduction of fluoroalkyl chains and could be reprocessed by hot pressing (130 °C, 10 MPa) and recover more than 70% of its toughness after reprocessing procedure.

Fourier-transform infrared spectroscopy, X-ray photoelectron spectroscopy, and solid-state nuclear magnetic resonance were used to demonstrate the presence of the grafted PVAc chains on the surface of the CNCs. Transmission electron microscopy images revealed the structure of the modified CNCs, which formed closely packed clusters due to the grafted PVAc chains. The thermal properties of the CNCs and their composite films were assessed by using differential scanning calorimetry, determining the appropriate temperature for the healing of the composite film. On this basis, the film was cut into two pieces and rejoined and healed in an oven heated at 40 °C for 6 h. The healed sample was viewed under an optical microscope and electron microscopy, demonstrating the efficacy of the healing process. An array of microindentation tests across the surface of the healed specimen was conducted to quantify stiffness, revealing no detectable differences between the healed and intact regions. This healing was found to only occur for the grafted-to samples and was not evident for the composites made of PVAc and ungrafted CNCs.

These materials feature a dynamic network structure, allowing them to behave like traditional thermosets at operational temperatures while exhibiting fluid-like properties at elevated temperatures. In this study, a space-grade epoxy thermoset matrix was transformed into a high-<i>T</i>_g vitrimer (<i>T</i>_g ≈ 200 °C) for potential use in composite applications.

These measurements enabled the development of time–temperature transformation diagrams, providing precise insights into the polymerization process.

Herein, we reported a facile and green process for fabricating biodegradable and flexible gold ion (Au³⁺)-coordinated cellulose-based light filters with diverse UV- and HEBL-screening capacities via adsorption of Au³⁺. The incorporation of Au³⁺ results in superior UV- and HEBL-screening performance, especially almost 100% absorption of UVA and UVB. Meanwhile, the films could block 67.9–98.8% of HEBL in the 400–450 nm region. By absorption of light, these films can efficiently filter blue light emitted by lighting systems, computer and mobile phone screens. The films maintained exceptionally high transmittance (83.2–86.9%) and low haze (2.1–2.4%). Furthermore, the films exhibited stable UV and HEBL screening under thermal treatment or UV irradiation. Quite encouragingly, the incorporation of Au³⁺ facilitates films in achieving desirable flame retardancy, evidenced by a significant increase in the limiting oxygen index from 19.2% to 39.2%.
