摘要：Since the 1950s, human beings have generated at least 6.3 billion tons of plastic waste. The vast majority of which are buried, incinerated, or discharged into the ocean, causing serious pollution to the natural environment. Seeking a green and sustainable strategy for cleaner production of recyclable bio-based and degradable cross-linked networks composites to replace thermosetting plastic composite materials is a challenge. To address the problem, a series of tung oil based, recyclable and degradable vitrimers based on dual dynamic reversible covalent bonds (dynamic ester and Diels-Alder bonds) were synthesized via UV curing and programmed heating. These vitrimers (PMFVs) demonstrated controllable mechanical properties, ease of processing, recyclability, shape memory capabilities, and chemical degradability. PMFV/MWCNTs composites, created by combining PMFV with multi-walled carbon nanotubes (MWCNTs) through electrostatic self-assembly and hot pressing, exhibited highly sensitive Joule heating performance and are suitable as deicing devices. Similarly, PMFV/GO composites, formed by combining PMFV with graphite oxide (GO) and hot pressing, can be used as effective fire/temperature early warning sensors, providing excellent fire/temperature alarm response within approximately 2 s when exposed to fire. These features provide a rapid, sensitive, and efficient way to prevent temporary fires or high temperatures. The resulted cross-linked networks/MWCNTs/GO composites with significant comprehensive advantages and will provide important inspiration for plastic recycling and reducing plastic pollution. ? 2025 Elsevier Ltd
