We reported a novel method of producing the cross-linked polybutadiene elastomer which could be thermally recycled like plastic materials without sacrifice functional utility. The commercial was first attached with furan via thiol–ene reaction, and network then built Diels–Alder click reaction between bismaleimide groups from polybutadiene. obtained polymer had good solvent resistance ambient temperature to 100 °C. mechanical properties modified tailored by amount ratio bismaleimide....

Pristine carbon nanotubes (CNTs) were activated to exhibit Diels–Alder (DA) reactivity in a polymer matrix, which was modified with monomers containing furan groups. The DA-active matrix transferred into dynamic reversible cross-linked inorganic–organic network via reaction CNTs, where pristine CNTs used as dienophile chemicals and furan-modified SBS acted the macromolecular diene. In this system, mechanical properties well resilience solvent resistance greatly improved even presence of only...

Abstract Polymers are ideal materials for information printing and storage encryption through multiple channels. In this study, the visible color, fluorescent, stress‐color combined to print information. Stress‐color is achieved using an acid‐tunable dynamic reaction between a β‐diketone amine group via light‐induced transformation of spiropyran (SP), which also directly prints color The fluorescent patterns stable SP released from enaminone structure. By achieving coding, data further...

Significance Camouflage has broad applications in nature, engineering, and the military. This work demonstrated a feasible strategy for adaptive visible camouflage based on light-driven dynamic surface wrinkles. The multiwavelength light–driven wrinkles photothermal effect–induced thermal expansion of substrate could tune light scattering visibility film interference color. Consequently, color captured by observer switch between exposure state that is distinguished from background similar to...

Though possessing advantages of durability and exceptional performances profit from cross-linked structure, it is challenging to recycle reuse thermoset polymers. Here, reprocessability in industrially relevant polyurethane polyurea thermosets unveiled. Unlike prior methods, this strategy does not require the complicated design monomer structures suitable for a variety systems. With enaminoneamide structure inserted, PU possesses reprocessing performance without affecting mechanical...

Abstract BRD1 encodes a protein containing bromodomain, which is an essential component of histone acetyltransferase (HAT) complexes. These complexes play crucial role in the regulation gene transcription and modification chromatin structures. The aberrant expression frequently observed across range cancer types, including hepatocellular carcinomas (HCC). However, precise mechanisms through contributes to tumorigenesis, especially HCC, remain unclear. In our investigation, we have uncovered...

Thermosetting materials exhibit advantages such as dimensional stability and elasticity but lack reprocessability due to their permanently cross-linked internal structure. Introducing a reversible network endows with often compromises resilience mechanical properties. Hence, it is still significant challenge develop recyclable elastomers high traditional thermosetting remolding ability thermoplastic materials. Based on this, this work incorporates both irreversible networks into polyurethane...
