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.

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.

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.

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.

These byproducts were useful for the understanding of reaction behaviors of reactive intermediates, such as the O/S exchange reaction and the backbiting reaction. The time course of the terpolymerization reaction indicated that phenyl isothiocyanate was consumed much faster than CO₂.

This opposite trend is due to the difference in the selectivity-determining step in the catalytic cycles. The ring-opening of oxetane is the selectivity-determining step owing to the small ring strain of oxetane in the present case, while the reaction of an alkoxide ion with heteroallene (CO₂ or isothiocyanates) is the selectivity-determining step in the previous case with the epoxide.
